While baking my oven appeared to short out making a popping sound with bright blue and white light shooting out the top vent of my Kenmore double oven. The breaker tripped. I turned it back on and the lower oven works fine but no matter what the top oven is set on it will not heat. I don't see any obvious burned relays or other parts. Any ideas on where to start? Thanks!
Answer Hello Wayne,
You should turn off the power and pull the bake element from the unit. Disconnect the wire from one side and make sure you can get test meter leads on the wire and the element end without shorting anything to ground. Make sure 120Vac is on both sides. If only one side has the voltage present, the other side of the circuit needs to be troubleshot for the4 trouble. Most of the time this turns out to be the relay on the control board but there is, in some cases, a thermal cutout that could be open. It appears that this one 318004900 is resettable so you should try pressing the button, (be sure the power is off since 120Vac will be on one side at all times power is supplied to the unit). Sometimes the button has to be wiggled to get it to reset. If this shows continuity, the board 316429800 will be the issue.
Neither lower, or upper elements get hot, the thermostat is good. Would the relay board be bad?
Answer Hello Mike. You need to make sure the thermal switches 318004900 are not tripped on the unit. If it is good, replace the control board on the unit.
The upper oven on my double oven does not heat at all. The bottom one works fine. Is there any easy way to tell if the problem is with the control panel board or the relay board?
Answer Hello Keith,
You should first check the safety thermostat 318004900 which is manually re-settable and opens the circuit to the heating elements. It is recognized by a dark red button in the center of it. Be aware that the power to the unit should be off before attempting to reset this thermal cutout since power will be on one or both sides of it on the naked terminals. If it has not tripped and the element checks out good, the issue is now most likely the relay on the control 316429710. There will be one safety thermostat for each bake compartment. These are normally on the back of the unit.
