I am a 73-year-old lady in the boonies of West Virginia. My pellet stoves about 43 years old has new combustion stove, new auger, new circuit board, new sensors, and new circulation fan. Stove was burning merrily this morning all of a sudden I saw a white flash through the vents and the stove went dead. Found the fuse thanks to an earlier post but does anybody have any ideas what could have caused the flash to start with. I looked in the back on both sides and could find no blackened wires could smell no wire burning smell. Would appreciate any help because will probably have to find the problem myself
