Place the oven thermometer in the middle of the upper oven cavity. Set the Bake on 350 degrees and do not open the oven door for about 10 minutes after the oven preheated. Open the oven door, check the temperature and post the result.

thanks gene,

here are the results : ( with thermometer hanging in the middle of the oven )

after 10 minutes at 350 bake the control panel read 165 the thermometer read 100…

after 20 minutes the control panel read 235 and the thermometer read 150…

after 30 minutes the panel read 260 and the thermometer read 180…

after 40 minutes the panel read 285 and the thermometer read 210…

it seems the bake element is not getting hot…

thanks for your help in advance

ira,

Did the Bake heating element get red while it was ON?

If not, remove the Bake heating element, disconnect the wires from its terminals and the heating element for continuity.

If the heating element is open, replace the heating element.

If the heating element is fine, replace the control board.

thanks gene…i am going to order the element as i replaced the control panel last week and the oven wasnt heating prior to that…at least with the new panel i can see how long its taking…thanks again and i will let you know the outcome after the element goes in…need both ovens as turkey day is fast approaching.

gene,
change out the bake elementand still not heating up. after about 45 minutes the panel read 350 but the oven thermometer read only 280. any other suggestion ?

thanks,

Do not open the oven door while the test is running. Open the oven door about 10 minutes after it beeped preheated to read the temperature.

Gene.

P.S. Did the Bake heating element get red while the oven was on?

gene,
i didnt open the door until after it hit 350…and i am not seeing the element getting red…something is getting the oven warm not the element…would love to return it as that wasnt the problem…just would like to figure out what is wrong with the oven and get it working…

thanks again

You said you replaced the control panel. Which part did you cal "control panel" #1 or #3 on the diagram?

You have to have a simple multimeter to perform the troubleshooting to avoid guessing and replacing unneeded parts.

gene,

i replaced both 1 & 3...my clock had been out for a while so i finally replaced it and when i did the touch pad went bad so i replaced that too....the top oven was not heating for a while and now after replacing the bake element i still dont have the oven heating up right. what else could it be ? i hate to call someone in if its someyhing i can do myself.

The heating element has to be checked for continuity.

If it’s fine then the voltage to the heating element has to be measured while the control calls for heat. The normal reading suppose to be about 240 VAC.

If the reading is incorrect and the wires between the heating element and the upper oven relay board (#11 on the (http://www.appliancepartspros.com/partsearch/model.aspx?model_id=49086&diagram_id=652538)) are good, the problem can be a bad upper oven relay board.
