Up to this point we have not found anything that is not working. The resistor burned up when my wife was using the bake function just when she pressed the stop button. I checked out the circuit board, found the burned up resistor and had her repeat what she did when the issue occurred. Everything worked. My mother-in-law has had this happen with two ovens in the past when a heating element burned up. Both the top and bottom heating elements appear to be working properly.
I think I can replace the circuit board myself but don't want it to happen again when I don't know what caused the resistor to burn up the first time (replacement board is $150-175)
Okay thank you for the information. One last question about the safety of continuing to use the oven as is until the circuit board is replaced. I know you can't guarantee but in your opinion is there any fire hazard related to continuing to use the oven with the burned up resistor? I am no electrical expert by any means but I would think the fire hazard occurred when the resistor burned up and should no longer be of concern. We may find through more use of the oven that something doesn't function properly but until then do you see a risk?
