Question about Frigidaire Ovens
Lower oven turns on (at least digital displays shows it's starting the process) but digital display never shows a temp. and oven never heats. Upper oven works and digital panel works. Any ideas before I call for a repair??

Remove the oven from the wall. Remove the rear panel.
The upper and lower ovens have a non-resettable thermal fuse that has blown.
Use a VOM to verify which fuse. After repair use Easy Off, not self clean.

The F2 Error code means the oven has detected an excess temperature condition. Most often this is due to a bad temperature sensor - the sensor costs about $75 from an online repair site.
How to remove and replace the temperature sensor. In most GE ovens, when you open the door, you'll see the rod-shaped temperature sensor sticking out of the back wall at the upper left. It's about six inches long and a bit more than 1/8" in diameter, held in place with two screws.
Turn off the circuit breaker (built-in ovens) or unplug the range before attempting the replacement.
The replacement sensor will come with instructions, but basically it's a matter of removing the sensor, pulling out the wires to where they are connected and disconnecting them. You may have to snip. The replacement sensor will come with high-temp wire nuts to hold the new connection. Polarity doesn't matter; it's a straight resistance thermocouple. Hook it up, be sure you poke the connections back far enough so that they're on the other side of the thermal insulation and not resting against the back of the oven.
If you continue getting the F2 error after replacing the sensor, then the problem is likely in the control module - this is the circuit board behind the keypad and clock.
You'll need to remove the decorative bezel to get behind the control panel. Remove screws and set off parts in order - it's not complicated. Once the bezel is off there are two more screws that hold the panel in place. Then you can lift the panel up about a half inch and pivot it forward toward you. You'll see a bunch of wires going to a circuit board.
On the panel you will notice some black plastic boxes that say "Potter & Brumfield" on them. These are relays. Check the relays - slide the black plastic cover straight up to expose the coil and the contacts. The coil, when energized, closes the contacts - look at all the relays. You can manually close the contacts with your finger (be gentle). If the contacts of one of them are stuck, they might be welded together. You can fix the problem by prying apart the welded contacts gently with a knife blade. Take some time to gently polish the relay contacts with a folded bit of fine grain sandpaper - this will get some more life out of them. Be gentle and careful - the relays aren't complicated but if you bend the contact or rip it out, you'll have to replace the controller, which will set you back a couple hundred dollars. If you unstick and burnish the relays, they will probably eventually weld together again as the rough spot will spark, but when you burnish them with sandpaper they should be good for some more life before they need to be replaced.
If the problem isn't the temp sensor or welded relay contacts then the problem is obviously somewhere else, but temp sensor and relay contacts will account for the lion's share of F2 errors.
Once again, be safe, be careful, be gentle. Ovens are not very complicated and they're tough, but always exercise care. Always disconnect electricity before messing with them.

If your electric oven is not heating then you probably have a bad heating lelement in your oven. This is not that hard to fix yourself...

PROCEDURE: Before proceeding, press OFF, OFF, START to enter Diagnostic
mode and verify the error codes. Ensure AM software, UI software and EEPROM
CHECKSUM versions appear on the lower text line. If AM software and EEPROM
versions do not appear, UI and AM may not be communicating. Verify this for the
lower oven UI and for the microwave (upper oven) UI. The lower oven UI will show
the AM software version for the lower oven appliance manager, and the microwave
UI will show the AM software and EEPROM versions for the microwave appliance
If the lower oven UI is not displaying the AM software version, go to UI IS NOT
DISPLAYING AM SOFTWARE VERSION.
If the upper oven UI is not displaying the AM software and EEPROM versions,
go to UPPER OVEN UI IS NOT DISPLAYING THE AM SOFTWARE AND
If lower oven UI and microwave UI are both displaying an error, go to LOWER
OVEN UI AND MICROWAVE UI ARE BOTH DISPLAYING AN ERROR.
UI IS NOT DISPLAYING AM SOFTWARE VERSION:
A. Unplug oven or disconnect power.
B. Open the back panels and make sure the P6 and P2 connectors are fully
inserted on the appliance manager and on the lower oven user interface board.
- If they are not plugged in, plug in connectors and go to step F.
- If they are plugged in, go to step C.
C. Visually inspect all wires between P6 on the appliance manager and P2 on the
lower user interface.
- Make sure wires are not cut or pinched.
- If the wires appear to be intact, perform a continuity check between
P6-1 of the appliance manager and P2-1 of the user interface board.
Complete for P6-2(AM) to P2-2(UI), P6-4(AM) to P2-4(UI) and P6-5(AM) to
P2-5(UI). All the measurements made should be less than 5 ?. If any of
these measurements exceeds 5 ?, go to step E.
D. Replace the appliance manager. Ensure all connectors are properly inserted.
E. Replace the wiring harness (signal). Ensure all connectors are properly inserted.
F. Replace all parts and panels before operating.
G. Plug in oven or reconnect power.
H. Observe for longer than 1 minute to determine if error has been repaired.
I. If error does not appear, initiate a bake cycle. Let the cycle run for at least
- If no error occurs, cancel the cycle, the problem has been repaired.
- If error occurs again, restart the troubleshooting procedure at step A.
At step D, replace the lower oven user interface board if appliance
manager has already been replaced.
- If both are replaced the problem has been repaired.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
