Temp Control Temp up arrow causes the temp display to lower in bake or broil mode. Result: I cannot set bake any higher than 350

There is no such thing as a hidden heating element.

First of all, most oven thermometers move very slowly compared to the electronic sensors and controls on the oven. To make sure you are getting an accurate reading, the thermometer should be in the center of the oven, the oven should be preheated, then wait another 20 minutes after the preheat beep. If the temperature is less than 35 degrees higher or lower at this point, it can be adjusted via the controls. Usually on GE ovens you press and hold bake and broil at the same time until SF comes up in the display. Then press bake, then use the arrow keys to raise or lower the temperature setting. If the temperature is more than 35 degrees off, you may have a bad sensor, bad control board, or other problem.

Good Afternoon! If your Whirlpool oven isn't heating to temperature, and your temperature sensor is reading good, the control board may be the issue. Fixyourboard.com can test and if necessary repair the control board in your oven. We back all control board rebuilds with an industry leading two year warranty.

Thank you!

There's a few things that can cause this.

1. Check to see if the both that Bake and Broil elements (burners) are heating up. Check the Broil element in Broil mode.

- during pre-heat the Broil element gets cycled on and off for short time durations to speed up the heating. If the Bake element is not working, then the oven will heat, but very slowly and never reach high temperature.

2. If the elements are both working, then it's possible that you have a bad temperature sensor.

- this is a temperature dependent resistance device that should measure 1080 ohms at 70 deg F (room temp).

3. If #1 and #2 are ok, then the problem is with your oven clock/control unit. We rebuild these at fixyourboard.com.

replace the electronic control board.the power surge may have damaged the boards circuits.

HI. an F-2 during a baking cycle is the result of an out of control oven temp that has reached Temperatures above 615F-630F

If this actual over temperature condition occurred, Look for welded relay contacts on bake or broil relays. If this happens, replace oven control (also called clock or ERC).

If no over temperature condition occurred, Look for a high resistance connection or any other cause of high resistance in the oven temperature sensor circuit. Check sensor, sensor harness and sensor harness connection at sensor and oven control. Replace sensor if found defective.

Remember: Oven control (ERC) measures resistance of sensor circuit , not actual oven temperature.

I found the manual online. Apparently my unit is malfunctioning and should work by just pressing bake temp and then selecting the temp...

After you hit the function you want...bake or broil...click the up arrow.  That should give you the default temp of 350 and the unit should light.  Now adjust to the temp you want.

after cleaning the oven the bake temp would not go any higher than 350. when you press the temp button to go lower or higher it only go down. could you tell me what is wrong or what to do.

The 350 as you stated is a default set point that you see before you start the cycle. What you should see afterwards (start bake) is the current temperature - which would normally be lower than the set or desired temperature - it will eventually get there
