Troubleshooting
This list will suggest situations that might cause this symptom.
1. Check the 3 lights on the back of the Circuit Board. These 3 lights are connected to 3 different
controls in this order - #1 - High Limit. #2 - Thermal C/O. #3 - Pilot Valve.
2. If the Pilot Valve light is Off, check the wiring from the circuit board to the module - Red wire
should be attached to the MV terminal - White wire should be attached to the MV/PV terminal
- Blue wire should be attached to the PV terminal and the Orange wire should be attached to
the #6 Terminal. There will be 2 Ground wires attached to the Module. #4 Ground wire to the
Gas Valve. #5 Ground wire to the cabinet.
3. If all the wiring is correct and still no Pilot Valve light, pull the Orange wire off of the #6 Terminal at
the Module and test the wire for 24VAC - if there is 24VAC, that means the Board is O.K. and the
Module is defective. If you do not see 24VAC at the wire, the Board is defective.
4. If the Thermal C/O Light is out - the Thermal C/O is defective.
5. If the High Limit Light is out - the High Limit is keeping the Heater off, (see Service Light).
