Troubleshooting Guide

Symptom	Possible Cause	Corrective Action
No heat	Power outage, thermostat setting, safety lockout	Check power supply; verify thermostat setting; reset primary control.
Burner won't ignite	No fuel, ignition failure, cad cell dirty	Check oil supply; verify ignition system; clean cad cell eye.
Frequent cycling	Dirty filter, limit switch, airflow restriction	Replace air filter; check limit switch; verify ductwork clear.
Smoke or odors	Dirty burner, improper combustion	Shut down immediately; call for professional service.
Unusual noises	Motor bearings, blower wheel, combustion issues	Identify noise source; schedule professional inspection.

Reset Procedure: Press RESET button on primary control once only. If problem persists, call for service.
