Amana: Ignition Lockout
What this fault means
The furnace ran through its ignition trials, never proved a flame, and locked out for safety. Many boards retry automatically after about an hour.
Likely causes
- Dirty or failed flame sensor
- Weak or cracked hot-surface igniter
- Low gas pressure or a closed manual valve
- Vent or condensate restriction on high-efficiency models
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
Ignition Lockout 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.
