Compatibility & Fitment
- Compatible with select residential and mobile home gas furnaces.
- Fits specific furnace units manufactured by Nordyne, Intertherm, Broan, and Miller.
When to Replace
- The furnace draft inducer motor runs and the gas valve opens, but the burners fail to light, causing the system to lock out.
- The ignitor heating element displays visible hairline cracks, structural breakage, or heavy white oxidation spots.
- The furnace diagnostic control board continuously flashes an error code indicating an ignition failure.
- Testing the ignitor wire leads with a digital multimeter displays infinite resistance (an open circuit).
Installation Tips
- Turn off the main electrical breaker to the furnace and shut off the incoming gas supply valve prior to servicing the unit.
- Never touch the dark heating element of the new ignitor with your bare hands; skin oils will create hot spots and cause the part to shatter when energized.
- Carefully insert the new ignitor through the burner box mounting bracket, as the element is extremely brittle and will snap if bumped against the metal housing.
- Route the wire harness exactly as it was originally placed, ensuring it is secured well away from the open burner flames and sharp sheet metal edges.
