Replaces / Cross-Reference Part Numbers

  • 62-22868-93
  • 62-22868-02
  • 62-22868-931PK
  • 62-22868-93-1PK

Compatibility & Fitment

  • Engineered for use in most Rheem, Ruud, and Weatherking gas furnaces.
  • Direct fit for models requiring part number 62-22868-93, including the Rheem Criterion furnace series.

When to Replace

  • Furnace blower runs but burners fail to light.
  • Visible crack, break, or burn spot on the ignitor element.
  • Ignitor does not glow at the start of the heating cycle.
  • Intermittent heating or frequent system lockouts.

Installation Tips

  • Disconnect electrical power and shut off the gas supply to the furnace before servicing.
  • Handle the new ignitor by its ceramic base only. Do not touch the silicon carbide element, as skin oils can cause damage and premature failure.
  • Ensure wire connections are secure using the supplied ceramic wire nuts.
  • Verify the ignitor is properly aligned within the burner assembly after installation.

FAQ

This hot surface ignitor is commonly associated with Rheem, Ruud, and WeatherKing furnaces. Compatibility can vary by exact furnace model and serial range, so the safest match is to confirm your original ignitor part number before ordering.
Commonly referenced part numbers for this ignitor include 62-22868-93, 62-22868-01, 62-22441-01, 62-23460-01, 62-22548-01, 62-22868-82, 62-22868-02, 025-32625-000, and Norton-271N. Always verify the original part number from your furnace parts list or the old ignitor when possible.
Typical symptoms include the furnace blower running but no heat, the inducer starting without burner ignition, repeated ignition attempts followed by shutdown, or visible cracking in the ignitor element. A weak ignitor may also glow but fail to get hot enough to light the gas consistently.
For many furnaces, this is a moderate repair that takes about 15 to 30 minutes. Basic tools usually include a screwdriver and possibly a nut driver. Shut off electrical power to the furnace and turn off the gas supply before starting. Handle the ignitor carefully, because the element is brittle and can be damaged by impact or skin oils.
Before replacing it, inspect the ignitor for cracks or a broken element, check the wire connector for heat damage, and make sure the furnace is actually sending power to the ignitor during the ignition cycle. It is also smart to inspect the flame sensor, burners, air filter, and venting, because ignition problems can sometimes be caused by poor airflow, dirty burners, or control issues rather than the ignitor alone.
These ignitors commonly fail from normal thermal stress after repeated heat cycles. Other causes include rough handling during service, contamination from touching the element, voltage issues, burner misalignment, or restricted airflow that causes overheating in the burner area.
Yes. Hot surface ignitors are fragile. Avoid touching the heating surface with bare fingers, do not overtighten the mounting screw, and make sure the replacement sits in the same position as the original so it is properly aligned with the burner flame path. If the connector style differs from your old part, confirm the wiring arrangement before installation.
