Whirlpool oven has an intermitting prob. the temp is not consistent. have changed the temp. sensor and the main control board. originally the oven would not work at all changed out the part above in Aug. Worked for some time and now the temp is not accurate. sometimes it cooks well, sometimes it burns the top of the food, sometimes it burns the bottom of the food. one time it did not work at all pushed it hard to the wall and it started working. could this be an issue with the panel control. does show f3e2 codes sometimes.:confused:

need help, Peytonjane
