Troubleshooting

Symptom	Possible Cause	Corrective Action
Furnace won't start	Power/thermostat/switch	Check circuit breaker, thermostat setting, service switch position
No heat	Gas supply/ignition	Verify gas valve on, check pilot/igniter, inspect filter
Short cycling	Filter/limit switch	Replace dirty filter, check high limit switch operation
Blower won't stop	Thermostat/fan limit	Check thermostat fan setting, inspect fan limit control
Unusual noises	Motor/bearings/ductwork	Inspect blower wheel, motor bearings, check for loose panels
Lockout condition	Safety device tripped	Reset power, check diagnostic lights, call for service if recurring

Reset Procedure: Turn power off for 30 seconds, then restore.
