My lower oven does not warm up to the indicated temp, the heating element doesn't work at all.
Answer Hello John. You need to test the element in the unit. If it reads closed for continuity, then it is good. If not, it is bad. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
My display is not working and neither is the oven. I hear the beeps when I press buttons on the display panel. The lights come on when I open the oven doors. Tested the fuse and the oven just beeped a few times. Is this a problem with the control panel/board? What would be the correct part to replace and the part number?
With the display not working, the first thing to check would be the control transformer. You will want to access the control board and test on the P16 connector which will be a 7 pin connector with 4 wires, 2 red and 2 blue. You will check across the 2 red from pin 5 to pin 7 for 120 vac and will test the 2 blue wire pin 2 to pin 3 for 12 to 24 vdc. If there is 120 vac into the transformer but not 12 -24vdc coming out then the transformer is faulty and would need to be replaced. If there is no power to the transformer then the control board is faulty and would need to be replaced. The control board part number for the unit is W10438751 and the transformer is part number 9760587.
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.
