I have a jenn aire JGR8875RDB oven. The control panel is partially out. The numbers beep. The clock displays and all the oven controls do NOT work.

Good Afternoon,
The control boards in your appliance may have failed. There is a display board, part number 71001799 and relay board part number 12001693. Commonly we see transformers on these relay boards fail with power surges. Luckily, we do test and repair these parts. Remanufacturing these controls will save you the high cost of buying new, and each rebuild will come with a 2 year warranty-- which is three times longer than new. Email me if you have any questions!

HI,

The problem is with the faulty relay board or wire harness harness.
There are no home remedies for this problem.The only solution is to get it repaired.

Check out www.appliancetimers.com They can rebuild your clock for around $100. A new Jenn-Air is like 2 grand.

Oven keeps beeping:
As there is no reprogramming of most control boards try this, disconnect the power and wait 30 seconds and then reconnecting the power.

If it's an "F1" fault code this generally implies an electronic oven control (EOC) failure. Disconnect the power, wait 30 seconds or longer and then reapply power. If "F1" returns upon power-up, replace the electronic oven control.
The oven control can be accessed and replaced from the rear of the control panel.

NOTE:Disconnect the power cord from the power source before removing the panel from behind the console.
If its an F2 ERROR CODE, The F2 error indicates an open circuit in the oven temperature probe.

if Your range has a resettable thermostat in series with the oven temperature probe. If this thermostat opens the clock will display F2 and the oven won't heat.
You can reset the thermostat by pushing in the reset button on top of the thermostat.
Some ovens have an alarm that will beep continuously every six seconds to alert you that the oven is still on. Usually, a kitchen timer that you have set will cause the beeping, but occasionally it can be an error with the oven's settings. If it is the kitchen timer, you can simply push the "Kitchen Timer On/Off" button to end the continuous beeping. If that does not stop the beeping, it is probably beeping due to an error. You can turn the continuous beeping off but you may still need to troubleshoot the issue that is causing the beeping noise.

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.

More then likely your electronic clock control board is going bad. After turning the power off, you can also try cleaning the connectors on the clock board and make sure the connectors are tight. 
 

You will need to replace the display assbly.
It is a very common problem with maytag/Jenn Air

can you hear audible tones form the machine when trying to set?? and just hte display has dimmed( amore normal complaint). all functions are working just the clock/display has dimmed to non readable state. if thats the issue youll need to replace the display part number 71003424 retails for about $165

I have the exact same problem with an F5 fault code. I also have a new clock assembly. RepairClinic.com said "Jenn Air fault code F5 = Hardware and watchdog circuits disagree / Replace clock assembly (also called the ERC)

Jenn Air Fault code for newer models F5 = Power to element relays disabled in cook mode
1. Intermittent oven temperature sensor or wire harness or,
2. Intermittent contact on power relay board"
This doesn't help since it is too technical. What should I do next?
