Our top oven has stopped working but the bottom oven works fine?
Answer Hi Steve. There are 3-limit switches inside the top of the unit. One is near the lt. front on top of a square cover it is part # WB24K5033. There is another to the lt. of the fan. It is part # WB24K5085. The other one has a red button (reset) in the middle and is on the back. It is part # WB24K5049. If you need to reset this then it is advised to replace it. Use a volt/ohm meter part # TJMA-DM1 to assist you in your diagnostics. They all normally read closed -0-ohms. If open (infinity) then replace them. You can temporarily bypass the thermostat for testing purpose only. Put the two wires together (tape them W/elect. tape)and does it come on now? Check the oven sensor part # WB21X5301 for 1100 ohms. Usually with high temperatures that shut the u8nit down (after cleaning) will wipe out the sensor as well. Thank You.
