Temperature not accurate on GE truetemp oven

Model JTP28w0f1ww double oven
Lower oven seems fine but upper oven temperature control is suspect as follows:
@ 350 on the digital pad the oven temp measures 325
@ 400 on the digital pad it measures 375
@ 450 it measures 450
I opened the oven to cool below 450; closed and it recovered to 450 and held.
I opened the oven again to cool below 400; adj the pad to 400 and it recovered and held to 400;
I then opened the oven to cool below 350; adj the pad to 350 and it recovered and held to 350.
Would you suspect the probe or the main board?
Can I check the probe without pulling out the oven from the wall?
Any help is appreciated.

SOURCE: Oven won't heat accurately

Brad, your right on track. But I'd look toward the sensor first (The computer only does what the sensor tells it to do). I'll need the model number to find part numbers to help you further. The model number is on a sticker located on the oven body behind the lower drawer. It'll start with 3 digits then a decimal point the more digits (xxx.xxxxxxxx).

SOURCE: oven tempture

The solution I am proposing here only applys to electric ovens and not micro wave ovens.
The usual reason for fluctuating oven temperatures is a faulty or out of calibration thermostat.
Some thermostats can be recalibrated, but in my experience, it is better to replace it.
Another reason for fluctuating temperatures is a badly fitting oven door, or a worn or faulty door seal, the door should be a good firm fit agaist the seal.
Plz rate my solution.
Thanks.

SOURCE: Jenn-air JJW9630CAS - double wall oven -door won't close, even after hinges replaced

On my double oven the bottom door was not closing by at least 21/2 inches the upper door would allow the light to stay on . Upon close examination this problem appeared to be the door was too low which did not allow the gasket to seat in the oven cavity, holding the door open. new hinges and receptors did not resolve this condition.This is how I corrected this condition. 1 open the doors one at a time and lock the hinges.2 remove the doors from the receptors (be careful they are heavy) and set aside. 3 remove mounting screws holding oven in cabinet. 4 slide oven forward enough to hold onto receptor sockets on left and right sides lower and upper 5 remove receptor sockets by removing the screws in front of oven(be careful to hold on to the receptor so it doesnt fall behind oven into cabinet)7 with a center punch punch a start point 1/8 inch above the existing screw holes and drill appropriate size hole for screw THE HOLES MUST MATCH UPPER AND LOWER RECEPTOR OR THE SCREWS ON THE LOWER DOOR WILL SCRATCH THE UPPER DOOR .8 attach receptors to oven in new holes 9 slide oven back into cabinet and replace screws removed in step three 10 attach doors into receptors and push locks forward into receptor cavity attach lower door first and check for operation then upper door open slowly and check enough clearance exists for the screws on the lower door miss the upper door . If more clearance is needed elongate the holes drilled earlier(repeat steps 1 through 5) and slide receptor up on upper door. NOTE The receptors are not in a sealed space in the oven cavity and are not exposed to any heat. Periodically check the screws for tightness. After performing this procedure Both doors close all the way and the light is no longer a problem Now 20 minutes cook time MEANS 20 MINUTES COOK TIME.
HOPE THIS RESOLVES YOUR PROBLEM !!!!!

SOURCE: Superba convection oven probe display problem

I had a similar problem today with my KitchenAid Superba wall convection oven (2002 model). I was roasting tomatoes at 225 degrees F for 3 or 4 hours when the control pad changed and showed that the probe was in use (never have I used it and had to look for it). I, too, tried to plug in the probe and take it out, but nothing changed. My worry was that I could no longer use the timed bake function. After trying to reset by turning off the oven at the breaker, with no change, I turned on the oven to 400 F and left it on for 10 - 15 minutes hoping that the high temperature would dry out whatever moisture that must have gotten in the place where the probe connects. Then I turned it off and just waited. After a half hour or so the control pad cleared and nothing showed (that is what you want when the oven is off!). Everything is back to working now.

Have a ge truetemp double oven model jkp27boa2bb. The control panel does not work. Turn the temp knob for lower oven and upper oven lite comes on. Is the control panel bad? Lower oven heats up only


The heating element on the top part off oven might be bad or a fuse that's located on back of oven either on or behind back panel.

I have GE model#JKP45WOP2WG double oven wall unit. Lower oven isn't heating up properly. Bottom of lower oven doesn't seem as hot as the top of the oven... replaced oven sensor, not


Most double wall ovens are technically two separate oven boxes. The lower oven box has its bake, boil elements, high limit thermostat and ofcourse its own oven sensor. If the lower oven box boil is working good and less heat on bake feature may suggest that the bake element is burned out and only getting preheated with boil element. Just a suggestion here

I have a GE double wall oven model JKP45WOA2WW and the oven will not bake or broil. Pulled one of the elemeents and it had continuity. The upper unit has not worked for some time. The lower oven just...


It is possible that there is a bad relay in the control board. This will shut off the power to your burner elements. The control board has a relay for the bake and broil element and one for the common for both. This is usually the one that goes bad. Unfortunately the board will need to be replaced or repaired. The control board will show temperature rise from the sensor but generally it doesn't show the cool down temp. This again is normal from my experience.

Top oven turns on for 5 sec and then goes off. Neither top or bottom coil in top oven gets hot. Does not work in Bake or Broil mode. Lower oven works fine.


On the following web page, part #238 is the temperature sensor for the top over, and would be a suspect component, but it could also be a bad oven control unit:
http://www.appliancepartspros.com/partsearch/model.aspx?model_id=216508&diagram_id=21205725#d21205725
Since the top and bottom oven both have the temperature sensor, you coud swap them out to check or verify the suspected bad sensor.
Otherwise, unfortunatey, it could be the expensive control unit. You could contact GE support- it's worth a shot- sometimes there are recalls, and they may be able to help. Here's their site:

Good luck, and hope this helps.

How do I find the part number for replacing control board for GE?


WB27T10290
I would not be so sure about that the problem is in the control board. Check switches on the door lock assemblies first.

Temperature is wrong


Many ranges show a beginning temperature that is higher than actual temperature, then the gap closes as it heats up.
Use a accurate oven thermometer to check your temps.
If it is faulty, it will not recalibrate to offset 200 degrees. You will have to replace the ERC.

Heating element on upper oven of a wall Thermador Oven


The control switch may be bad on it. If there are 2 elements on the top, they both are not bad at the same time.Check to see if the wires have not burned off the control switch first. Check to see if your breakers are O.K. Turn them both(maybe 3) off and then reset.

Electric Oven doen't heat


cdkd, there should be a TC0, on the back of the oven. Thermal cut out. You want to check to see if it is open. You will have to pull the oven out enough that you can remove the back panel cover and check it. The lower and upper oven should have one. It's a very cheap part to replace. If this TCO fails, no heat. Check this first before buying a new board. Catriver..post back.
