What This Part Does

The igniter electrode is part of the furnace ignition system. When the thermostat calls for heat, the ignition control board sends voltage to the electrode, creating a spark that ignites the propane burner.

Once ignition occurs, the furnace can begin heating and circulating warm air throughout the RV.

If the electrode fails to spark or properly detect flame, the furnace may shut down as a safety precaution.

Signs Your Furnace Igniter Electrode May Need Replacement

You may need to replace the igniter electrode if your furnace experiences:

• RV furnace clicking but not igniting
• Furnace blower runs but burner will not light
• Furnace tries to ignite then shuts down
• Repeated ignition attempts
• Visible cracks or carbon buildup on the electrode

Replacing the igniter electrode is one of the most common repairs for RV furnace ignition problems.
