My clock is no longer working. The oven has power because the light comes on when I open the top oven door. Yet nothing else is working at all. When I try to start either oven, the start button beeps, but nothing else happens. What needs to be replaced?
Based on the information, this issue sounds like it is caused by a faulty control transformer. You can test the transformer at the control board by checking for 120 vac on connector P16 from pins 5 to 7. If there is 120 vac there then test for 12-24 vac at the same p16 connector from pins 2 to 3. If there is not power then replace the transformer 9760587.
Whirlpool oven GMC275PRS01 does not hold steady temperature.
I may vary 20+ degrees above and below set temp. ie....set to 350 degree and it may go to 370 and then go to 320 and start back up to 370 again. What control board effects this??
Answer Hello Leo. The main board W10438710 is the board that turns the element on and off based on the reading from the oven temp sensor W10131825. However, the temperature inside the unit should fluctuate above and below the setting on the board. You can take the upper and lower numbers and add them together and divide by 2 and you should have a number around the setting you programmed the board to.
