Whirlpool Oven Not Heating Properly

Oven/Range/Cooktop Repair

Hi,

My Whirlpool Super Capacity 465 (RF380LXKQ) electric range is not heating properly. I used a digital meat thermometer suspended below the middle rack to check temperature. This way I could have the display outside while the door was closed.

When set to a temperature the preheat indicator comes on and the oven counts down the time till ready. However when the time hits zero it is not at the proper temperature. If I set it for 400F it will only be 300F when the time ends. If I raise temperature to 415F it will eventually settle out around 400F.

I tried using the Oven Temperature Control adjustment in the manual but the amount that it is off by changes with temperature. In order to get it to settle around 450F I had to have the oven set to 470F.

Any suggestion on what the problem is / how to troubleshoot it? I really don’t want to buy a new oven.

Hello,

Check the oven sensor for continuity at the control board connector. The normal reading suppose to be about 1100 Ohms at the room temperature.

If the reading is incorrect, replace the oven sensor.

If the reading is correct, replace the oven control board.
