Jenn-air ove3n flashing a error FR - Jenn-Air WW30430P Stainless Steel Electric Double Oven

FR Second oven error sensed

The unit never detected a sufficient rise in temperature in the second oven.

My 20 year old electric Jenn Air range recently flashed the F7 error code and beeped repeatedly. I shut off the circuit breaker until it cooled. The next day I turned it on and everything seemed fine. We baked a pizza and the
erro repeated when the oven was shut off.
I opened the front panel and noticed the wire ribbon connecting the front panel to the display was slightly askew. How that happened is beyond me. I pulled out the ribbon hold down clips, pushed the ribbon in all the way, and
replaced the hold down clips. The range is now working properly after replacing nothing.
The cheapest fix possible.

F-7 error code means that the Function Key is stuck or shorted out. You will have to replace the touch pad or if the touch pad is part of the clock, you will have to replace the clock (ERC).

F1 - E1
EEPROM checksum error
1.
Disconnect power for at least 30 seconds.
2. Re-apply power and observe for
at least one minute.
3. If code re-appears, replace control board (also
called ERC or clock).

Note: Applies to all F1-E...
codes except F1-E3.

This appears to be a communications error between the control boards. There is a test mode that you can enter from the panel, which might help you diagnose the problem further:

1. Turn power at break off. Wait a few minutes. Turn power back on.
2. Push and hold "Stop Time" key for 10 seconds
3. Now you are in test mode. You can push each button to test it's function while you hold it down.
4. Push cancel to exit test mode.

If you conclude a control board failure is the problem then we may be able to save you some money. If you can have the board removed, we repair them at www.fixyourboard.com

F-2 error for jenn-air means the oven is to hot, it could be the oven temperature sensor is faulty, or the relay board.

It seems you have a stuck button. Here is a list of fault codes:

Slone, F4 is the code for a shorted temperature sensor. This is the temp probe in the oven. There are 2-quarter inch screws holding it on. It should pull out through the insulation until the quick connect comes through. If you want to make sure, the sensor should ohm out at 1143 ohms at 100 degrees. I think you can be pretty sure that this is the problem. The part number I have is 704657. Catriver.
