A. TROUBLESHOOTING
: When testing electrical equipment, always follow standard electrical procedures
and precautions.
1. Check for line voltage (110-120VAC) to the furnace. If there is no line voltage applied to
the furnace, check that disconnecting switch is “on”, fuses or circuit breakers have not
blown or tripped.
2. Make sure thermostat is “calling for heat”.
3. Check for adequate fuel supply and pressure. Are all the fuel shutoff valves are open?
