I have a Jenn Air Electric Double oven Model JJW9830DDP. When baking it takes a long very time to heat up and once it gets up to the temperature setting it sometimes stops heating and does not hold the temperature. Broil seems to work ok. Display works ok. I have tried preheating with the broiler and this works as long as I set the bake temperature above the preheated temperature. If I set the bake temperature below the preheated temperature then the oven stops heating.

Hi,

If your electric oven is taking too long to heat or just not heating up right, then check out this tip that will give more detail about your problem.

Looking at the schematic I see 2 possibilities:

1. I think the most likely cause is a failed "limit switch" aka "thermal fuse" aka "temperature cutout". For each oven there is a limit switch that feeds power to both elements. So the upper limit switch is probably tripped which would kill power to the upper bake and broil elements. The limit switch is usually located on the back wall of the oven cavity.

2. There are a relay board for each oven. Be sure you changed the right one.

Put a thermomiter in the oven and set oven to 350. Once oven says it has reached temp. Give it about 15 min and check the thermomiter you placed in the oven to see if it maches.

This is where I would start.

There are 3 things that can cause this:

1. Bake or Broil element faulty. The oven cycles these on and off to reach and maintain the average setpoint temperature. If the elements heat poperly during the time they are ON, then they are OK (may be able to see them glow).

2. The temperature sensor probe is faulty. This can cause the oven to think it's hotter than it actually is.

3. The above two causes can be easily diagnosed by a technician with an ohm-meter. If they are both OK, then the problem is in the controller itself. If this is the case you may want to have us repair the controller. We see this fault quite often.

Hope this helps you out.

Hi, this will happen over a period of time and its just heat related. the control panel isn't insulated properly and , there has been a larger than normal transfer of heat to the inside of the control panel where the circuits are housed.

If this is a problem, i recommend replacing the control board. it will fix the dim issue.

I just tried the suggestion to cut the power to the oven from the box for 1 minutes, and it worked! I feel like I just earned a day's pay!

Good Morning!
What youre experiencing could be a result of a faulty oven temperature sensor, a faulty oven control board or relay board. Youre more than welcome to send both the main control board and relay board for evaluation. Fixyourboard will test and repair both as needed for less expensive than buying new, and include a two year warranty.

This means that the Power to element relay energized during time of day display. You have a problem with the wiring harness and it is shorted or you need to change the power relay board (PRB). If it is a double oven, you need to change second oven board.

It's not dumb, it's the oven. You simply hit bake, temperature and then bake again. Of course you have to choose whether to bake or convection bake and you choose this when you hit the first and last bake command.
