PHCAB50 issue

[heymax81]

My PHCAB50 stopped working and I had blown the 5 amp fuse on the Circuit Board. I replaced it and the light on the thermostat turned on but the minute I tried to turn the thermostat up the fuse blew again. I’ve checked as much as I know and the fuse keeps blowing. Any suggestions would help. I have replaced the Auger Motor, Thermostat , Circuit Board, Room Fan. Snap Disc with no luck the Exhaust Fan has continuity as well. There seems to be a short somewhere. As I have already stated. Once I replace the fuse and shut the Thermostat off and plug the stove in. The light on the thermostat comes on and is green. The second I turn the thermostat up it blows the fuse. I’m clueless. Help

I'd start by pulling all of your wires off of the control board, assuming you can do this. Unplug the stove, first. The check for continuity on all of the devices. When you get it, you found your problem. You might need to go around your vacuum switches as they may create a break in the circuit and hide a short if it is down stream of the switch.
When you say the exhaust fan has continuity, are you saying it is shorted? If so, there's your problem.

It was the igniter that was shorted. I replaced it and the Stove works but the Igniter won’t shut off. If you plug in the stove with the Thermostat in the off position, the igniter still starts glowing red and won’t stop. ?????

Almost sounds like you've fried something in the control board?

I’ve tried a New Motherboard. Something seems backwards. Everything is working now except the Igniter staying on all the time. I’m almost wondering if it could be the exhaust probe or the Temp probe might be bad. ?
