632625 Hot Surface Furnace Ignitor

Key Features

  • Direct replacement hot surface ignitor designed to safely and consistently ignite the gas burner assembly in residential heating systems.
  • Constructed from high-density, temperature-resistant materials to withstand rapid heating cycles and prevent thermal shock cracking.
  • Includes a factory-crimped, high-temperature ceramic wire harness and plug block for a secure, plug-and-play electrical connection.
  • Engineered to exact original equipment resistance specifications for optimal heat-up timing and immediate gas ignition.

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.

FAQs

Based on the available cross-reference information, this ignitor is commonly used on furnaces from Nordyne, Intertherm, Broan, Miller, and Gibson. Compatibility can vary by exact furnace model and serial range, so the safest match is to confirm your original ignitor part number before ordering.
This ignitor is associated with part numbers 632625, 1016290S, 632625R, N1016290S, ACI1000-16, and 151026-1539. Matching your existing part number is the best way to confirm fit.
A failed hot surface ignitor often causes a furnace that starts the draft or inducer motor but never lights the burners. Common symptoms include no heat, intermittent ignition, burners failing to ignite after the startup sequence begins, or a visibly cracked ignitor element. In some cases, the furnace may shut down and retry ignition several times before locking out.
Yes. The 632625 is a hot surface furnace ignitor. During a call for heat, the control board sends power to the ignitor, which heats up until it can ignite the gas at the burner. If the ignitor is weak, cracked, or electrically open, the furnace may go through part of its startup sequence without lighting.
Replacement is usually a straightforward repair for someone comfortable working inside a furnace cabinet. In many cases, the job takes about 15 to 30 minutes. Typical steps include shutting off electrical power to the furnace, turning off the gas supply, removing the burner compartment panel, unplugging the old ignitor, removing its mounting screw or bracket, and installing the new one in the same position.
Before replacing the ignitor, disconnect power to the furnace and inspect the old part for a visible crack or an open circuit. Also check the wiring plug, harness condition, burner cleanliness, and whether the control board is actually sending power during the ignition cycle. If the burners are dirty or the flame path is disrupted, a new ignitor alone may not solve the ignition problem.
Yes. Furnace ignitors are fragile and should be handled carefully. Avoid touching the heating element area with bare fingers if possible, do not strike it against the burner assembly, and make sure it is mounted exactly as the original was. Misalignment or contamination can shorten ignitor life or cause ignition failure.
