This code typically points to
- Inducer not starting within 20 seconds
- Inducer RPM out of valid range
- Lost inducer RPM signal for 5 seconds
- Vent restriction
- Failed inducer
- Wiring fault
Next checks to confirm
- Verify inducer operation and RPM
- Inspect venting/combustion-air path
- Inspect motor wiring
Escalation
Repeated code with free venting and correct power points toward inducer or board failure.
