Furnace Repair Services › Furnace Igniter Replacement
Furnace Igniter Replacement in Portland, ME
The hot surface igniter is the ceramic element that glows red-hot to ignite the gas burner each time your furnace starts. When it fails, the furnace tries to start, the gas valve opens, nothing ignites, and the control board shuts everything down as a safety measure. You get no heat and usually a blinking error code. Igniter replacement is one of the more common furnace repairs we make — and one of the more straightforward when it's actually the igniter causing the problem.

When to Call
When You Need Furnace Igniter Replacement
- Your furnace runs the blower but you hear no ignition and the house won't warm up.

- Your furnace worked this morning and stopped this afternoon with no obvious cause.
- A previous tech told you the igniter was cracking and you want it replaced before it fails completely.
How It Works
Our Process for Furnace Igniter Replacement
- 1
Confirm the Actual Fault
We check the control board error code and test the igniter's resistance with a meter. A failed igniter has a distinctive reading — we confirm before we replace.
- 2
Igniter Removal and Inspection
We pull the igniter carefully — they're fragile. We also inspect the burner assembly and flame sensor while we're in there, since they fail in sequence sometimes.
- 3
Replacement and Startup
We install the correct igniter for your furnace model, cycle the furnace through a full startup, and confirm the burner lights on the first attempt consistently.
- 4
System Check
Before we leave, we verify the flame sensor is reading correctly, heat exchanger shows no visible cracks, and the control board has cleared all fault codes.
Portland Context
Why this matters in Portland
Portland's winters mean furnaces here run hard from November through April — sometimes beyond. That's a lot of ignition cycles per season, and igniters in systems over eight years old are often near the end of their reliable service life by the time they actually fail.
Straight Talk
About pricing & scope
Igniters are inexpensive parts, but the diagnostic work to confirm that's actually what failed is where the time goes. If we find the flame sensor or gas valve is also contributing to the problem, we'll tell you before adding anything to the repair.
