Replaces / Cross-Reference Part Numbers

• 632625
• 632625R
• 1016290S
• N1016290S
• CMF95 M7RL
• CMF95/M7

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.
