When your heat cuts out overnight, furnace pilot light repair Ashland OH gets your system firing again without the guesswork. We handle furnace pilot relight, thermocouple swaps, and flame sensor cleaning for homeowners in Downtown Ashland, Ashland Heights, and the University District. One call, one visit, and your furnace is back online.
Furnace pilot light repair Ashland OH is the diagnostic and repair service that restores a standing pilot flame or electronic ignition sequence so your furnace can fire and heat your home. A pilot that won't stay lit usually points to a failed thermocouple, a dirty flame sensor, a weak gas valve, or a draft pulling the flame off the orifice. We test each component with a thermocouple tester and multimeter before we replace anything.
In Ashland, most pilot failures show up during the first hard cold snap in October and November, when furnaces that sat idle all summer fire for the first time. Older homes near Historic Ashland and the Riverfront District often still run standing-pilot systems with 20-year-old thermocouples. If your pilot light won't stay lit in Ashland OH, we can usually diagnose it in under an hour and have parts on the truck for Carrier, Trane, Lennox, Goodman, Rheem, York, Bryant, and American Standard units.
Every pilot light call includes a full ignition-system diagnosis, not just a relight. Here is what is covered in a standard visit, and what we treat as an add-on if we find it.
We test the thermocouple, flame sensor, igniter, gas valve, and control board with a multimeter and thermocouple tester. You get millivolt and pressure readings, not just a verdict, so you know exactly what failed.
We pull the pilot assembly, clean the orifice and thermocouple tip with a wire brush, and clear any rust scale or dust blocking the flame. A dirty orifice is one of the most common reasons a pilot will not hold.
If the thermocouple reads under 20 millivolts or the flame sensor is fouled, we replace it with an exact-match part for your Carrier, Trane, Lennox, Goodman, Rheem, York, Bryant, or American Standard furnace.
We leak-test every gas connection at the valve and union and verify inlet and outlet pressure with a manometer. If pressure is off, we adjust it to the manufacturer spec before relighting the pilot.
We inspect the heat exchanger with an camera and run a combustion analyzer at the supply plenum. If we find a crack or elevated carbon monoxide, we shut the unit down and walk you through the next step.
We run the furnace through a complete heat cycle, watch the flame for stability, and check temperature rise. The job is not done until the pilot holds and the house is warming up.
We ask three questions: what brand is the furnace, what does the pilot do when you try to relight it, and is there any gas smell. That tells us whether to send a standard van or an emergency truck. Most calls are booked within a two-hour window.
The technician checks for gas leaks at the valve and union, verifies the thermostat call, and inspects the heat exchanger with an inspection camera for cracks. This takes 10 to 15 minutes and happens before any repair work begins.
We pull the pilot assembly and test the thermocouple output in millivolts, check the flame sensor with a flame sensor tester, and verify gas pressure at the valve with a manometer. Each reading gets written down so you see the numbers, not just a verdict.
We replace the failed part, clean the pilot orifice with a wire brush, and relight the pilot. On electronic ignition systems we verify the igniter spark and confirm the control board is sending the signal. This step runs 30 to 60 minutes depending on access.
We run the furnace through a full heat cycle, watch the flame for stability, and check the temperature rise at the return and supply. Then we walk you through what failed, what we did, and how to keep it from happening again next winter.
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Reads millivolt output from the thermocouple under load. Anything under 20 millivolts cannot hold the gas valve open, and this is the fastest way to confirm it.
Traces the ignition circuit from the thermostat through the control board to the gas valve. We use it to find where the signal stops, so we replace the right part.
Measures inlet and outlet gas pressure at the valve and checks pressure switch operation. Correct pressure is what keeps the pilot flame steady and blue.
Reads carbon monoxide and combustion efficiency at the supply plenum. Every pilot repair ends with a reading so we know the burner is burning clean.
Confirms the flame signal on electronic ignition systems. A weak microamp reading is why a burner lights and then shuts down seconds later.
Lets us look inside the heat exchanger for cracks without pulling the whole furnace apart. Cracks are a carbon monoxide risk and a stop-work finding.
Cleans rust scale and dust from the pilot orifice and thermocouple tip. A dirty orifice is one of the most common causes of a pilot that will not hold.
A homeowner in South Ashland spent three nights relighting a pilot that dropped out by morning. The thermocouple read 11 millivolts under load, well below the 20 millivolt threshold needed to hold the gas valve open.
We replaced the thermocouple, cleaned the pilot orifice, and verified the flame held through four full heat cycles. The house went from 58 degrees to 70 in about two hours. Total job time was 75 minutes.
An emergency call came in at 11 p.m. from Brookside. The pilot lit fine but the burner never fired, so the house was blowing cold air. The gas valve was getting voltage but not opening.
We replaced the gas valve, leak-tested every connection with a manometer, and confirmed outlet pressure at manufacturer spec. The furnace was running full heat by 12:45 a.m. Carbon monoxide reading at the plenum was zero.
A rental near the Ashland University District was short cycling every 30 seconds. The tenant thought the pilot was failing, but the burner was lighting and then shutting down on a weak flame signal.
We cleaned the flame sensor, verified the microamp reading, and replaced a clogged filter that was overheating the furnace. The unit ran full 15-minute cycles with a temperature rise of 42 degrees, right in spec.
Most pilot calls fall into a handful of failure patterns. Here are the ones we see most often in Ashland County, and how we handle each one.
Ask a pro →We test thermocouple output in millivolts and inspect the pilot orifice for blockage. Nine times out of ten it is a thermocouple under 20 millivolts or a dirty orifice. We replace or clean the part and verify the flame holds through a full heat cycle.
We test valve voltage and outlet pressure with a multimeter and manometer. If the valve is not getting the signal, we trace back to the control board. If the valve is getting voltage but not opening, we replace the gas valve and leak-test every connection.
We inspect the venting, test the pressure switch with a manometer, and check the pilot tubing for cracks. A combustion analyzer reading at the plenum tells us if draft is pulling the flame off the thermocouple. We correct the root cause, not just the symptom.
We check gas pressure at the valve, clean the orifice, and verify the pilot flame is blue and steady. If the flame stays yellow after cleaning, we test the gas valve and adjust pressure to manufacturer spec. We also run a carbon monoxide test before we leave.
“Our 1920s furnace kept dropping the pilot every cold night. The tech tested the thermocouple, showed me it was reading 12 millivolts, and swapped it in about 40 minutes. He also cleaned the orifice and checked for gas leaks. Two months later the pilot has not gone out once. Straight answers and no upsell.”
Dana R.Homeowner, Historic Ashland
✓ Verified“Called at 11 p.m. on a Sunday when the pilot would not stay lit and the house was down to 58 degrees. A technician was here in about 90 minutes. Turned out to be a failing gas valve. He had the part on the truck and we had heat before 1 a.m. Fair price for an emergency call.”
Marcus T.Homeowner, South Ashland
✓ Verified“Our flame sensor was dirty and the burner kept shutting off, which I thought was a pilot problem. They cleaned the sensor, tested the whole ignition sequence, and explained what to watch for. Also flagged that our filter was clogged. Honest work and they cleaned up after themselves.”
Priya S.Homeowner, Ashland University District
✓ VerifiedTurn the gas valve to Pilot, press and hold the reset button, and hold a lighter to the orifice for 30 to 60 seconds. If the flame will not hold after two tries, stop and call us. A pilot that drops out repeatedly usually means a failed thermocouple or a dirty orifice, and forcing it can push unburned gas into the chamber.
The three most common causes are a worn thermocouple reading under 20 millivolts, a dirty pilot orifice, or a draft pulling the flame away from the thermocouple tip. In older Ashland homes we also see failing gas valves and cracked pilot tubing. We test each one with a thermocouple tester and multimeter so you get the real cause, not a guess.
