Have HVAC Questions? Ask an HVAC Expert for Answers
It sounds like the problem may be with the heating element in your unit has went bad which can cause this to happen. Have you checked the heating element?
So do those units not have heating elements?
is your unit getting power at all?
You can check the board to see if its getting power. Did the lighting hit your unit?
It sounds like the control board is fried and will need to be replaced. That is the only thing that makes sense.
Why was it missing one connection and two wires? That may very well be your problem was it not the same board? Did you have to replace the new board with old parts?
It can if all the parts were not there that were supposed to be. That means something is wrong with the electrical aspect of it. That is why it keeps blowing the fuses.
I am going to go ahead an open this up to other experts to see if anyone else can assist you with this. I believe the problem is with the control board but I cant be certain of course.
Hi there happy to help.
How old is the unit? What specific parts have you replaced, and are you qualified to safely work on electrical equip?
