Greetings,
I have a KitchenAid drop in range/oven that will not maintain a constant temperature. For example, if I set it to bake at 350, the chime will sound in a few minutes to indicate it is up to temp, the display will read 350, but in reality it is only 200 or so, according to an oven thermometer. I can then increase the temp to 450 and it will climb to more than 475. If I then lower it back to 350 it will drop back down to below 300.
I replaced the hidden bake element 2 years ago because it was bad, and it has worked fine until recently. Can someone please point me in the right direction?
Thanks,
Norman

Hi. You should check the oven sensor and it's connector plug. At room temperature the resistance should be about 1100ohm. Replace if needed Part number: 9782081

Ok, I checked resistance on the oven sensor and got a value of 1790 ohm (sensor was still mounted in oven chassis). Am I to assume this is too far out of spec and I need a new sensor? Please advise.
Thanks

Hi.
The resistance is way off. Can you describe, please how did you check it.Was it at room temperature?
Simon.

Yes, at room temperature. Removed panel on rear of the range, isolated the sensor by unplugging it, set the meter at 2K ohms and plugged the test leads into the back side of the sensor plug. I did not remove the sensor from the range. Checked it several times and consistently got 1791 on the meter.

Thank you, I have ordered a new sensor and will post the results when it arrives and I get it installed.
Thanks again.

New sensor arrived in only 2 days, but didn't seem to help.
Replaced the sensor, set to 350. In 20 minutes the oven only got to 325. Set it up to 450, 4 minutes later it had only reached 350, then 12 minutes after that, it finally got to 450. I tried setting it back down to 350 and in 15 minutes it was at 385, 15 minutes after that it was at 330. These temps are all checked by an oven thermometer, which I have no way of verifying, so it's hardly scientific.
I was really hoping the new sensor was the answer, but the original problem seems to remain. Any more ideas?
Thanks for your help.
Norman
