I'm having an issue with my GE JDP36 oven.
When I try to set the baking temperature or broil, it will appear to start preheating (ex: I enter 350 degrees, the display panel will read 100 degrees as though it is preheating), then w/in about 30 seconds, it shuts off. Power is still on, but the temperature set cuts off and the oven does not preheat.
I'm thinking it has to be in the control panel, and I have the front panel pulled apart. But this is a costly part, so I'd like some advise before trying this. Also, if this is it, I would like to know how complicated this is to replace as it appears all the wires from the new control panel will need to be rewired.
Any help is appreciated.
Thanks!

It is not that hard to rewire if you have the right tools and parts, like high-temp leads and a Klein tool to crimp the leads on. Here is a manual that may be some help: https://dl.dropboxusercontent.com/u/8010163/GE%2024%20inch%20Self%20Cleaning%20Range%20Service %20Manual.pdf

Thank you for sending this.
Do you know much about this oven? Do you think it is likely the control panel? This is a pricey part so I want to be fairly certain before spending the money.
Thanks you again for your response.

I would not recommend replacing anything unless the meter says that it is bad. Fix the wiring and see what it does. Check the oven out with the meter, which is an easy task, and you will know if anything needs replacing.

OK - I'll check it out with the meter.
Thanks for you help! Happy holidays to you!

Dr. Tom,
I'm finally getting around to taking these measurements.
I hate asking a really stupid question - obviously I'm not very electrically savvy and have no business messing with this stuff but for lack of money have to make an attempt.
I'm looking at the manual you sent and when it tells you the ohm measurement I should be getting, for example for the bake unit (pg 15 of the manual you sent) - I should get a reading of 21 ohms - when I do this - do I leave the wires connected or disconnect? If disconnected, am I taking the reading across the wire connections or the control panel component?
Also, I assume power is off - for resistance, I can get the readings when the power is off, right? I'm leary about any power being on, for obvious reasons.
Same questions for all these components - broil, sensor connection...

Also, how much deviation is allowed in a measurement for the component to be considered 'good'?

I have tried to look at your dropbox link on how to use testing equipment, but I only am able to see the 1st couple of pages for some reason.
I'm sorry for the elementary questions.
Thanks!

First, turn the breaker off. Resistance is measured across the calrod itself, @ the screw terminals, wiring can be left on. Never measure resistance across any hot wires or you will blow the safety fuse or the meter. 5-10% variance is acceptable. 21 ohms = 18-23

Thanks for your reply.
Another stupid question... What is a calrod? Are you talking about the contact on the component? What I really want to check is the components on the control panel.
Thanks again!

Calrod is the heating element.

But if I'm measuring across the calrod, that won't tell me if the component on the control panel is bad which is the component I'm suspecting is faulty.

Your earlier post referred to testing the bake element. That was my reference.
