Lennox: Blower or Inducer Motor Fault
What this fault means
The Lennox control cannot run the inducer or variable-speed blower as commanded and shuts down.
Likely causes
- Failed motor or capacitor
- ECM module fault
- Wiring/connector fault
What you can safely check
- Replace a dirty air filter — restricted airflow causes a surprising share of furnace faults.
- Confirm registers and the outdoor unit are clear of snow, leaves and debris.
- Cycle power at the switch once and let the system retry.
Call a technician — don't keep resetting this
Blower or Inducer Motor Fault is a high-severity fault. Repeated resets of a safety lockout can mask a serious problem such as a cracked heat exchanger (a carbon-monoxide risk) or a failing compressor. If you smell gas, leave and call FortisBC at 1-800-663-9911 or 911 first.
