I have a KING KP130 pellet stove i've had for about 4 years now with no issues until today. Ran it for a few hours in the morning with no issue, let it cool and cleaned it out. Went to turn it back on and the board lost power, opened it up to find the main 8A fuse blown, replaced it with another 8A fuse and it blew about 10 seconds after turning back on. Replaced with a 3rd 8a fuse and left the back off and watched as the stove started up. The 2 resistors immediately above the auxiliary fuse caught fire and burned up. Are these resistors tied into the ignitor/aux fuse? Could a bad ignitor cause this issue? I've attached a picture with the resistors that burned up circled

Which fuse blew?
More than likely they are tied to the igniter. But the resistors popping means there is a dead short somewhere, could be igniter. Hard to diagnose without a multimeter. I would guess the resisters have now either sent power and popped to someplace it wasn’t meant to or they are open and something isn’t getting power. Damage may have occurred to other devices also.

sorry for the late reply, the main board fuse originally blew, the 8amp. Wierd part about the whole situation is, i disconnected each thing, exhaust, blower, auger, ignitre, so forth and hooked them back up one at a time. The 2nd fuse had blown immediately after startup but the 3rd one held until i reconnected everything and then these 2 resistors blew? I'm so confused on whats going on and there are no local techs that deal with these in my area
Well the thing with fuses is to kill power so damage cant go any further. But you cant troubleshoot with out it. I use a poor mans dim bulb tester that allows 120vac but limits amperage (board killer) in your case i would recommend a new board just because it more than likely damaged components in the circuits.
yeah 100% figured i need a new board, trying to trace down what caused this failure to begin with is the trouble i'm currently having..
Igniters have been notorious killers for years if they fail to ground. Most just fail open now, but still can fail badly
Ok the fuse that blew. The fuses are labled what they go to, so if the resistors by the ingniter triac burned that fuse near them should be your igniter fuse. Is that the one that blew?
