Disconnect the black power wire where it is connected to the furnace with breaker off. Put a wire nut on it and then turn the breaker on. If it continues to trip, the problem is not the furnace and you will have to trace the power wire back to the breaker box to find problem. Next, disconnect the black wire from the breaker (with breaker off) and then snap breaker on. If it trips, bad breaker. If the furnace was disconnected and breaker did not trip, you have a short either on the P C Board or the transformer.
Look on the circuit board for a small fuse. Replace if necessary. take a small piece of wire and with the door safety switch taped down, jump out R and W terminals on circuit board. Unit should power up. You can also jump out R and G terminals and room air blower should turn on. If nothing, replace circuit board.
check the fuse, I believe it is a 3 Amp , there is also a safety switch, when you remove the panel it is on the top you can push it in and the light should light after a few seconds. Hope this helped Tim
Its a simple fix. Follow the cord that plugs into the wall into the furnace. Or if its hard wire, follow the romex wire that goes into your furnace. Inside the furnace, switch the white and black wires that connects to the power cord. www.fastacservice.com
You need to trace the path of electricity. With it unplugged, remove the cover and look at the wiring from the power light on, Its possible that a wire burnt off, you will be able to see it easily if so. If its an internal short, like inside the thermostat or power switch, then you need a meter to accurately find the problem, or change parts and hope to get lucky.
First make sure the thermostat is working right. Make sure the wire connections on the valve are good and tight. If all good, culprit is the thermocouple or pilot generator also called a thermopile. Different style and names, all have the same purpose.
