What is included
What our furnace ignition repair includes
Every ignition call covers the full light-up sequence, not just the part you called about. Here's what's included in the standard diagnostic and repair, and what we treat as an add-on only if you approve it.
Full ignition sequence test
We run the furnace through its call-for-heat sequence and watch the inducer, pressure switch, igniter, gas valve, and flame sensor in order. That tells us exactly where the sequence breaks instead of guessing at the part.
Igniter resistance and continuity test
A multimeter checks the igniter for the resistance range your furnace expects. A cracked or shorted element reads out of spec, and we show you the reading before we replace it.
Flame sensor cleaning or replacement
The flame sensor gets cleaned with steel wool and tested for microamp output. If it won't hold a steady reading, we replace it. Dirty sensors cause the same lockout as a bad igniter.
Control board voltage verification
We confirm the board is sending 120 volts to the igniter circuit. If it isn't, the board is the problem, not the igniter. This step prevents you from paying for a part you didn't need.
Combustion and CO safety check
A combustion analyzer reads the flue gas for carbon monoxide and efficiency. We verify CO stays under 9 ppm and check the heat exchanger for cracks before we call the job complete.
One-year parts and labor warranty
Every igniter, flame sensor, and control board we install is warrantied for one year. If the same part fails next season, the replacement is on us, including the labor to swap it.

Service overview
What furnace ignition repair Lima OH actually involves
Furnace ignition repair Lima OH is the diagnostic and replacement work that restores the spark or hot-surface element lighting your gas burners. Modern furnaces don't use a standing pilot; they use a silicon nitride or carbide igniter that glows orange at roughly 1,800 to 2,500 degrees Fahrenheit, or a spark electrode that fires at the burner. When that part cracks, shorts, or drifts out of resistance spec, the control board locks out after three failed tries and your blower never gets the signal to push heat.
Lima winters hit single digits, and a furnace that won't fire turns a bad morning into a frozen-pipe emergency fast. If you're searching for furnace igniter repair near me Lima, the usual culprits are a cracked igniter from thermal stress, a dirty flame sensor reading false, or a control board that stopped sending 120 volts to the igniter. We see this most in older homes around Cercado de Lima and San Martín de Porres, where furnaces run hard from October through April.
- Heat back the same day — We stock igniters for Carrier, Trane, Lennox, Goodman, Rheem, Bryant, York, and Amana on the truck, so most furnace ignition repair in Lima OH near me calls finish in one visit. Average diagnostic plus replacement runs two to three hours, and you're warm before dinner.
- Full safety inspection included — Every ignition repair comes with a combustion analyzer check on the heat exchanger, a flame sensor reading, and a limit switch test. We verify carbon monoxide stays under 9 ppm in the flue before we call the job done. That's OSHA safety compliance and ACCA standards in practice, not a sales pitch.
- Affordable furnace igniter repair Lima Ohio — A universal igniter kit runs less than a manufacturer-specific part, and we tell you which one your furnace actually needs. Typical 2026 pricing for igniter replacement lands between $180 and $420, including the diagnostic. No surprise add-ons after the fact.
- Licensed, insured, code-correct — Our techs hold Ohio HVAC license credentials and NATE certification, and we pull permits when a gas valve or control board swap requires it. Work is warrantied for one year on parts and labor, so if the same igniter fails next winter, you're covered.
- Stocked trucks, fewer return trips — Our vans carry igniters, flame sensors, thermocouples, and control boards for the ten most common furnace brands in Lima. That means same day furnace ignition repair Lima is realistic, not a promise we walk back when the part isn't on the shelf.
- Straight pricing before we start — You get the diagnostic fee and the repair range up front. If the igniter is the only failed part, you pay for the igniter. If the control board also failed, we tell you before we order it. No surprise line items on the invoice.
- We test, we don't guess — A furnace ignition fix Lima starts with a multimeter reading, not a hunch. We check igniter resistance, flame sensor microamps, and board voltage. If the readings say the part is fine, we keep looking instead of selling you a part you don't need.
- Emergency and 24/7 availability — When your furnace quits at 2 a.m. in January, we answer. Emergency furnace ignition repair Lima OH calls get dispatched overnight, and we prioritize homes with infants, elderly residents, or frozen-pipe risk. Call (419) 287-8289 any hour.
The service timeline
How our ignition repair process works
Phone triage
You describe the symptom: clicking with no light, short cycling, or cold air from the vents. We ask for your furnace brand and ZIP, then dispatch the closest tech. Most Lima calls get a two-hour arrival window, and emergency furnace ignition repair Lima OH requests get priority overnight.
On-site diagnosis
The tech pulls the burner door, checks the igniter with a multimeter for resistance and continuity, then tests the flame sensor with a flame sensor tester. A clamp meter confirms the control board is sending voltage. This takes 20 to 30 minutes and tells us exactly which part failed.
Part replacement
We replace the failed igniter, flame sensor, or thermocouple with an OEM or universal part rated for your furnace. Gas valve and manifold connections get leak-tested with a manifold gauge set. Most swaps take 45 to 90 minutes depending on cabinet access.
Combustion and safety check
After the part swap, we run a combustion analyzer on the flue, verify the flame sensor reads steady microamps, and check the limit switch and heat exchanger for cracks. If carbon monoxide reads high, we stop and walk you through options before anything else runs.
Test run and walkthrough
We cycle the furnace through three full ignition sequences to confirm it lights every time, then show you the old part and the readings. You get a written summary of what failed and what to watch for next season. Payment is due on completion, and the one-year warranty starts that day.
Tools and methods01 02 03 04 05 06 07 08 09 10 11
Tools and methods we use on ignition repairs
Multimeter
Reads igniter resistance and continuity, and verifies control board voltage output to the ignition circuit. This is the first tool out of the bag on every no-light call.
Flame sensor tester
Measures the microamp signal the flame sensor sends back to the board. A reading below spec means the sensor needs cleaning or replacement.
Combustion analyzer
Reads flue gas for carbon monoxide and combustion efficiency. We verify CO stays under 9 ppm before we call any ignition repair complete.
Manifold gauge set
Checks gas manifold pressure and leak-tests connections after any gas valve or burner work. Essential when ignition problems trace back to fuel delivery.
Clamp meter
Measures amp draw on the inducer motor and blower motor. A weak inducer won't prove draft, and the igniter never gets the signal to fire.
Inspection camera
Lets us look inside the heat exchanger for cracks without pulling the whole cabinet. Important when ignition problems come with a CO reading above normal.
Thermocouple tester
Used on older standing-pilot furnaces to check the thermocouple's millivolt output. If it won't hold a signal, the pilot won't stay lit.
Sequence-of-operation testing
We follow the furnace's call-for-heat sequence in order: thermostat, inducer, pressure switch, igniter, gas valve, flame sensor. The first step that fails is where we focus. This method prevents part-swapping and keeps your repair cost down.
Resistance and microamp verification
Igniters and flame sensors have published spec ranges. We compare your part's readings to spec with a multimeter and flame sensor tester. If it's in range, we keep looking instead of replacing it.
Combustion safety verification
Every ignition repair ends with a combustion analyzer reading and a heat exchanger inspection. We follow ACCA standards for combustion testing and OSHA safety compliance for gas appliance work.
OEM and universal part matching
We match the replacement igniter to your furnace brand and model, using OEM parts when available and universal kits when they meet spec. Carrier, Trane, Lennox, Goodman, Rheem, Bryant, York, and Amana are all stocked or readily sourced.
Where this service helps
When to call for furnace ignition repair
Your furnace quit on the first hard freeze of the season and the house is dropping below 60 degrees overnight.
We dispatch an emergency ignition tech with igniters and flame sensors on the truck. The diagnostic takes about 20 minutes, and most repairs finish the same visit. Heat restored the same night, with a CO check to confirm the furnace is burning clean.
You're a landlord with a tenant calling about no heat and you need it fixed before the weekend.
We prioritize rental no-heat calls and carry parts for Goodman, Rheem, and other common rental-grade furnaces. One trip usually covers diagnosis and repair. Tenant has heat, you have an invoice with the part and warranty documented for your records.
Your furnace is 12 years old and the igniter has failed twice in three winters.
We test the board voltage and check for power surges or short cycling that's burning through igniters. Sometimes the fix is a board replacement, not another igniter. You stop paying for repeat igniter swaps and get a furnace that lights reliably through the season.
You smell gas near the furnace and the igniter is clicking without lighting.
We treat gas smell as an emergency. The tech checks the gas valve, manifold connections, and igniter, then leak-tests with a manifold gauge set before restoring operation. Leak isolated and repaired, ignition restored, and the system verified safe before we leave.
Local execution
How ignition repair runs in Lima, Ohio
Lima's climate drives ignition failures harder than most markets. We get single-digit overnight temps from December through February, and furnaces here run six to seven months a year. That thermal cycling cracks igniters faster than in milder regions. The housing stock matters too: a lot of Lima homes were built between 1920 and 1970, and the furnaces in those basements and closets are often older units with less clearance, which makes the repair slower but not impossible. We also see propane furnaces in the rural parts of Allen County, and those need a different orifice and igniter setup than natural gas. If you're searching for affordable furnace igniter repair Lima Ohio, the honest answer is that most jobs land between $180 and $420 because the part itself is inexpensive and the labor is straightforward once we've confirmed the diagnosis. We pull permits when a gas valve or control board swap requires it, and we follow Ohio HVAC license requirements on every gas-side repair.
Cercado de Lima
Older housing stock with basement furnaces and tight clearances. Igniter swaps here often need the burner assembly pulled for access.
San Martín de Porres
Mix of rentals and owner-occupied homes. We see a lot of Goodman and Rheem furnaces with flame sensor issues from dust and pet hair.
San Borja
Newer construction with high-efficiency furnaces. Ignition faults here often trace to the control board rather than the igniter itself.
Lurín
Larger lots and some propane systems. Propane ignition needs a different orifice and manifold pressure setting than natural gas.
Single-digit overnight temperatures from December through February
Igniters cycle more often and crack faster. We stock extra igniters in winter and prioritize no-heat calls overnight.
Aging furnace stock in pre-1970 homes
Older cabinets have less clearance, so repairs take longer. We plan for an extra 30 minutes on these jobs and carry flexible tools.
Rural propane systems in outlying Allen County
Propane burns hotter and needs a different igniter and orifice setup. We carry both propane and natural gas parts on the truck.
Dusty basements and pet hair in return air
Dirty flame sensors are common. We clean the sensor as part of every ignition repair and check the filter before we leave.

Before and after
What a successful service visit changes.
Clicking furnace restored to steady heat
Before
A homeowner in Cercado de Lima had a furnace clicking for two days with no light. The house was at 58 degrees, and the igniter read open on the multimeter. The flame sensor was also dirty and reading low microamps.
After
We replaced the igniter with an OEM part and cleaned the flame sensor. The furnace lit on the first try and held steady through three test cycles. House was back to 70 degrees within two hours of our arrival.
Maintenance: Change the filter every 60 days during heating season and have the flame sensor cleaned annually. A dirty sensor is the most common cause of repeat lockouts.
Control board failure misdiagnosed as igniter
Before
A landlord in San Borja had a tech replace the igniter twice in one winter. The furnace still wouldn't light. The board was sending intermittent voltage to the ignition circuit, which was burning out each new igniter.
After
We tested board output with a multimeter and found the voltage dropping under load. Replaced the control board, and the original igniter design held. No repeat failures in the following season.
Maintenance: If you've replaced an igniter twice in two years, ask for a board voltage test. Repeat igniter failures usually point upstream.
Emergency overnight ignition repair
Before
A family in San Martín de Porres called at 11 p.m. when the furnace quit and the house dropped below 60 degrees. The igniter had cracked from thermal stress during a cold snap.
After
We dispatched an after-hours tech with an igniter on the truck. Diagnosis took 20 minutes, replacement took 50. Heat was back before 1 a.m., and the CO reading was verified at 4 ppm.
Maintenance: Keep the area around the furnace clear and schedule a pre-winter tune-up in October. Most igniter failures show up on the first cold snap.
Problems we solve
Ignition problems we fix for Lima homeowners
A furnace that won't light shows up in a few predictable ways. Here are the ones we see most in Lima and what happens if you let them ride.
Furnace clicks but never lights
The house loses heat fast, and pipes in crawl spaces or exterior walls can freeze within hours when overnight temps drop into the teens. We test the igniter with a multimeter and replace it if it's cracked or out of resistance spec. If the igniter is fine, we check board voltage and the gas valve. Most clicking-no-light calls are fixed in one visit.
Furnace lights then shuts off after a few seconds
Short cycling wears the igniter and board faster and leaves the house cold in cycles. It also points to a flame sensor that isn't proving flame. We clean or replace the flame sensor and verify microamp readings. If the sensor is fine, we check the board's flame-sensing circuit. This is one of the most common ignition-related lockouts we see.
Furnace blows cold air with no ignition attempt
No ignition attempt usually means the board isn't getting a signal from the pressure switch or limit switch, so the sequence never starts. We test the inducer motor, pressure switch, and limit switch for continuity and voltage. A tripped limit switch from restricted airflow gets reset after we check the filter and blower.
Burning smell or soot near the furnace
A burning smell on a new igniter is normal for the first hour, but soot or a persistent smell points to incomplete combustion or a cracked heat exchanger. We run a combustion analyzer and inspect the heat exchanger with an inspection camera. If CO reads high or the exchanger is cracked, we stop the repair and walk you through replacement options.
Pricing and expectations
What furnace ignition repair costs in Lima
$180 - $700 depending on parts and timing
Typical 2026 pricing for furnace ignition repair Lima Ohio runs $180 to $420, including the diagnostic and the replacement igniter. A flame sensor cleaning is often under $150. If the control board also failed, expect $450 to $700. The diagnostic fee is credited toward the repair when you approve the work. We quote the range before we start, and we don't add line items after the fact. The part itself is inexpensive; most of the cost is the diagnostic time and the labor to access the igniter.
You're paying for a correct diagnosis, a part that matches your furnace, and a combustion safety check that confirms the system is burning clean. A cheap igniter swap that misses a failing board costs more in the long run.
Igniter type and brand
OEM igniters for Carrier, Trane, and Lennox cost more than universal kits. We tell you which one your furnace needs and whether a universal part meets spec.
Access and cabinet clearance
Older furnaces in tight basements take longer to open up. If we have to pull the burner assembly to reach the igniter, labor goes up by 30 to 45 minutes.
Additional failed parts
If the flame sensor, control board, or gas valve also failed, the repair cost rises. We test each part and quote the additional work before we proceed.
After-hours or emergency timing
Overnight and weekend calls carry an emergency dispatch rate. We tell you the rate on the phone before we send a tech.
Permit requirements
Gas valve and control board swaps sometimes require a permit in Allen County. We handle the paperwork and include the cost in the quote when it applies.

Customer stories
What Lima homeowners say about our ignition repair
Marcus T.Homeowner, Cercado de Lima
Furnace was clicking for two days and blowing cold. The tech tested the igniter with a multimeter, showed me the crack, and had a replacement on the truck. Ninety minutes later we had heat. He also checked the flame sensor and the CO reading before he left. Fair price, no upsell.
Elena R.Homeowner, San Martín de Porres
Called at 6 a.m. when the furnace quit overnight. They had a tech at the house by 8:30. Turned out the control board stopped sending voltage to the igniter, not the igniter itself. He explained the difference and didn't just swap parts. Heat was back before noon.
David K.Landlord, San Borja
I manage four rentals in Lima and use these guys for every no-heat call. They diagnosed a dirty flame sensor on one unit and a failed igniter on another in the same week. Both fixed same day. They know Goodman and Rheem systems well, which matters when you're turning units fast.
How much does furnace ignition repair cost in Lima OH?
Most ignition repairs in Lima run $180 to $420 in 2026, including the diagnostic and the replacement igniter. A flame sensor cleaning is often under $150. If the control board also failed, expect $450 to $700. We quote the range before we start, and the diagnostic fee is credited toward the repair when you approve the work.
Who repairs furnace igniters in Lima Ohio?
Lima Furnace Repair Pros repairs furnace igniters across Allen County, including ZIP codes 45801, 45804, and 45805. Our techs carry OEM and universal igniters for Carrier, Trane, Lennox, Goodman, Rheem, Bryant, York, and Amana furnaces. Call (419) 287-8289 and we'll dispatch the closest van, usually within a two-hour window.
Why is my furnace ignition not working in Lima?
The three most common causes are a cracked igniter from thermal stress, a dirty flame sensor reading false, and a control board that stopped sending 120 volts to the igniter. Lima's cold snaps make igniters work harder, so we see more failures in January and February. A multimeter test tells us which part failed in about 20 minutes.
Can a bad igniter be repaired in Lima OH?
No, a cracked or shorted igniter gets replaced, not repaired. The element is ceramic and can't be rewelded or patched. The good news is the part itself is inexpensive and the swap takes 45 to 90 minutes. We stock the common sizes on the truck, so most Lima homes get heat back the same day you call.
