Electronic Ignition Repair in Portland, ME
Electronic ignition replaced standing pilots on most furnaces made after the mid-1990s. There are two types: hot surface igniters that glow red-hot to light the burner, and intermittent pilot systems that spark on demand. When either fails, the furnace attempts to start, comes up short, and shuts itself down — often locking out after a few tries. We identify which ignition type you have, test the components properly, and replace what's actually failed.

When to Call
When You Need Electronic Ignition Repair
- Your furnace clicks repeatedly but the burner never lights on a cold Portland night
- The furnace runs fine for a week, then starts locking out every few days
- You can hear the inducer start up but the igniter never glows
- Your furnace error code points to repeated ignition failure with no other obvious cause
How It Works
Our Process for Electronic Ignition Repair
- 1
Error Code Retrieval
We read the furnace's fault codes from the control board to confirm ignition failure and rule out other triggers.
- 2
Igniter Resistance Check
We measure the hot surface igniter's resistance. A reading outside the manufacturer's range means it's failing even if it still glows.
- 3
Spark System Inspection
On intermittent pilot systems, we check the spark gap, ignition cable condition, and module output voltage.
- 4
Replace and Cycle Test
We install the correct igniter or module, then run multiple heat cycles to confirm reliable ignition before leaving.
Portland Context
Why this matters in Portland
Portland winters put furnaces through heavy cycling from November through March. That repetitive thermal stress cracks hot surface igniters faster than in milder climates. We see a lot of them on furnaces that are otherwise in good shape.
Straight Talk
About pricing & scope
Hot surface igniters are consumable parts and their cost varies by furnace brand. Some older ignition modules are no longer manufactured new, which may require sourcing a reliable aftermarket equivalent.
