Do you have a meter where we can do some step by step troubleshooting?Also give me full model from label inside unit
Lest go one step at a time. With door switch held in check between Line-H black and white LINE -N for 120 volts.Then from XFMR-H black and XFMR-N white and make sure we have 120 volts.
AC volts. Lowes setting above 120 (Probably will be 200)
Try meter in a known powerlocation like a receptacle to make sure we have it set right and meter is working
If 120 on both Next lets check for 24v from transformer back to board.
If not120 on both let me know
Lets check at the disconnect supplying power to unit. (Both in and out)
Main power coming in.Usually a disconnect or switch outside on unit
Yes also check the actual circuit breaker in main panel that provides power to furnace
OK locate the wires where they come into the unit.If they are connected with a wire nut, check there. Now one note here. While doing these tests, you will have to have door switch held in to have power where I told you to check, (L1 and Neutrals). If you did not have switch held in, hold in and re check.
Did you have door switch in earlier?Now one note here. While doing these tests, you will have to have door switch held in to have power where I told you to check, (L1 and Neutrals). If you did not have switch held in, hold in and re check
OK find where the wires enter the furnace and check here. If we do not have 120v at the board we are loosing it somewhere between board and circuit breaker.
