Top-rated independent heating and cooling across central Arkansas and the Arkansas River Valley
Ignitor & Flame Sensor Repair
We repair and replace furnace ignitors and flame sensors for homeowners across Arkansas, Louisiana, Missouri, Mississippi, Oklahoma, Tennessee and Texas. If your furnace hums, clicks and tries to light but the burners shut back down after a few seconds, or the blower runs cold air and the system locks out after several attempts, that is usually one of these two parts. Set the thermostat to heat, check the breaker and change a loaded filter, then call us for heating repair. Do not open the gas train or burner compartment yourself.

What ignitor and flame sensor work actually involves
Both parts sit in the burner area and both are wear items. A hot surface ignitor glows to light the gas, and over years of cycling it cracks or loses resistance until it stops glowing. The flame sensor is a thin metal rod that proves flame is present. When it films over with oxide, the control board never sees flame and closes the gas valve as a safety measure. That is the short flame followed by a shutdown. We pull the parts, test them properly and replace what has failed.
What we check and install on the visit
We start at the control board and read the fault code, then watch a full ignition cycle so we can see whether the ignitor glows and how long the flame holds. We measure ignitor resistance, check flame signal in microamps against the manufacturer spec for that board, and inspect the sensor rod, ceramic insulator and wiring. If gas pressure, a dirty burner or a blocked flue is the real cause, we tell you that instead of selling a part. Replacements are matched to your furnace model.
How we decide replacement is the right call
Numbers decide it. An ignitor that reads open, or one that glows weakly and delays light-off, gets replaced. A flame sensor with a low microamp reading that does not come back after cleaning gets replaced, because a marginal signal will drop you out again on the coldest night. If the readings are healthy, we keep looking at pressure switches, the inducer, the board and venting. Across the region we see plenty of furnaces where a lockout was really a drainage or airflow problem, and swapping parts would not have fixed it.

Can a dirty flame sensor be cleaned instead of replaced?
Often yes. Light oxide comes off with the right abrasive and the flame signal returns to spec. If the reading stays low after cleaning, or the rod is pitted or the insulator cracked, replacement is the reliable fix.
Why does my furnace light and then shut off after a few seconds?
That pattern usually means flame is lighting but the sensor is not proving it, so the control board closes the gas valve. It can also be grounding or wiring. We test the flame signal to confirm which.
How long do ignitors last?
It varies with how often the furnace cycles and how clean the airflow is. Many go several heating seasons and then fail during a cold snap. A restricted filter causes extra cycling and shortens ignitor life.
How it works
- Step 1
Tell us the symptom
Call or fill out the quote form and describe what the system is doing. Warm air, short cycling, water on the floor, a smell, a noise. That detail tells us what parts to load on the truck.
- Step 2
We diagnose on site
A technician checks the thermostat, the electrical side, airflow through the filter and coil, refrigerant behaviour and the ductwork. You hear what we found in plain language before anything gets replaced or repaired.
- Step 3
You approve the fix
We explain the repair, what it costs and what happens if you wait a season. Nothing gets done without your go-ahead, and we tell you honestly when a repair no longer makes sense.

Why homeowners call us
- We know humid-climate systemsAcross the region the real enemy is moisture. Systems here run long hours pulling water out of the air, and that shows up as frozen coils, clogged drains and mildew smells. We diagnose for humidity, not just temperature.
- Mixed gas and heat pump workPlenty of homes we visit run a heat pump with gas backup, and the two have to hand off cleanly. We troubleshoot both sides, including defrost boards, reversing valves, ignitors and heat exchanger concerns.
- Attic ductwork is our daily breadMid-century homes often have ducts running through attics that hit brutal temperatures. Crushed runs, disconnected boots and leaking joints steal cooling before it reaches the room. We find them instead of blaming the equipment.
- Repair before replaceA capacitor, a contactor, a blower motor or a clogged drain line fixes a lot of the calls we take. We would rather fix what you have and tell you plainly when the numbers stop working.
