Temp. problems on a GE wall oven

I have a GE wall oven 24" electric jrp20. When I turn it on to any temperature. the readout will climb to what I had set it for, but it the oven is not as hot as it reads, then I set the temp. to 500 and I after a while I got a F2 error that I looked up online and it showed the temp. went over 600. What could be the problem? Thanks!

    If you are sure that the bake element is coming on and you have no problems with voltage to the oven I would replace the oven temp sensor. It can be remove from inside the oven by taking out 2 screws. Pull out harness and all and just plug in the new one. It is # 253 on this diagram cost is $73.49 from this site Part # is WB21X5301.

    You can use an ohm meter to check resistance on the probe. If it checks open then you know it is bad. Normal value is 1091 ohms at 75 degrees F. The problem is the resistance changes at higher temps. and you don't know what it is doing at those high temps. Unless you want to take the time to put a thermometer in the oven and check it according to the scale at different temps. You can use this scale if you want to try that:


    Temperature (°F)
    Resistance (ohms)

    32 ± 1.9
    1000 ± 4.0

    75 ± 2.5
    1091 ± 5.3

    250 ± 4.4
    1453 ± 8.9

    350 ± 5.4
    1654 ± 10.8

    450 ± 6.9
    1852 ± 13.5

    550 ± 8.2
    2047 ± 15.8

    650 ± 9.6
    2237 ± 18.5

    900 ± 13.6
    2697 ± 24.4

    Sorry if the scale looks a little jumbled but it breaks up as follows: (75 degrees F +/- 2.5 degrees = 1091 ohms +/- 5.3 ohms), (350 deg. F +/- 5.4 deg. = 1654 ohms +/- 10.8 ohms) etc.

What's the wiring diagram for a GE wall Ovens digital readout

There should be a diagram somewhere on the oven. Usually on the top or back or if not, inside the terminal block cover where the electrical supply wires go into the oven. Make sure its turned OFF before you remove any covers.

My GE #JRP15WOP2WG wall oven, manufactured in about 1995, only starts heating if I put the temp at 550. It gets extremely hot, then I have to turn it down to 520 in order for it to click off. Unfort

Good Morning! I would check the oven temperature sensor first. There are a lot tutorial videos that can be found by Googleing, "How to test my oven temperature sensor." If the sensor is good, and reads 1100 ohms at room temperature.. then the issue youre experiencing is likely control board related. Given that the part is no longer available new, the oven board will have to be rebuilt. Fixyourboard does this and offers a 2 year warranty with each remanufacture.

It sounds like this is a common occurance among GE ovens.
Shut off the power at the box, then remove faceplate then remove the keypad.
after doing so, remove it from connector, and clean pins with an eraser.
Make sure the terminals are clean of debris, and check for a reset button on the back of the keypad.
I hope this helped you out.
