The oven was on and the clock and everything when off and smoke started to come out of the top panel. We disconnected everything and took out the panel. The circuits were burned. Do you know what may have caused this? Can we safely install a new one?
ANSWER Hello Anne,
This could have been caused by a short to ground, a power surge from the utility board, or simply a defective board. To check for a short unplug the unit and check from each prong to the units' chassis. With the exception of the center prong, (or two center prongs depending on whether you have a two or three prong power cord), you should read no contact. If you read contact to chassis ground from either of the two side prongs on the cord, you will need to trace the circuit to locate the short. This is done by following the harness up to the next connector and disconnecting it. If the short goes away, the problem is in the connector you just dis-connected. Continue up the harness in this fashion until the short is located. If no short is evident, you will have to assume the issue was in the board and all that can be done is to replace the part.
