I replaced the Control Board (part AP4343818), which I got from you, on my kitchen aid range. It fixed the issue and the oven controls are working again. However, suddenly the oven does not heat fast enough or not at all (only if I turn on broil but if I use the regular bake function it is stuck in preheat). Any idea of what it could be? Thanks a million.
Answer Hello J.W.,
You should go to the bake and the broil out terminals and check from one to the other and there should be 240Vac. If there is only 120Vac, you have dropped a leg and the unit will not operate properly. If this is the case, to isolate the issue, discontinue the power supply to the unit and remove the wire from the terminal, (bake then broil), making sure the wires cannot touch anything before powering the unit back up. Test from chassis ground to the wire while set to bake, then broil, for 120Vac. If there is no voltage present, the bake or broil element would be opened or there is a wiring issue. If it is there but no voltage on the terminal, verify 120Vac input to the board. If it is not present there is a wiring issue on this 120Vac leg of the power supply. If it is, the relay on the board has failed. Diagnosis could be more accurate, with part numbers, if we had the units' model number.
Oven works on convection setting only. Won't heat up or work on bake. what part do I need?
Answer Hello Steve. Check and make sure the element and wiring in the unit is good. If so, then you will need to order and replace the control board W10181438 in the unit. You can test this with a multi-meter TJMA-DMT3.
