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
open?
4. To assist you in troubleshooting this furnace, it is equipped with an integrated
ignition control with diagnostics. These diagnostics evaluate what malfunction
the control system has experienced and will activate a flashing light on the
control in different sequences to help pinpoint the failure.
