After 15 or 20 minutes the unit tourns off by it self.

Hi.

E1 and F5 (F5-E1) means that the Self clean latch will not lock. The problem is usually fixed replacing the door latch. If the door latch is working, check wiring to door latch. The control module causing the error is not very common but possible. If the latch and wiring are OK, check control board.

Here troubleshooting from manual:

1. If door latched:

1. Disconnect power from unit.
2. Check wires and connectors from control to door switch, then from door switch to control. If no damage to wires and all connectors okay, proceed to step C.
3. Replace door switch.
4. Re-apply power.
5. Press and hold any key down for 1 minute to clear F5 failure code from memory. F2 will appear. Press CANCEL and observe for 1 minute to ensure operation is correct.

2. If door not latched:

1. Disconnect power from unit.
2. Check wires and connectors from control to latch switch, then from latch switch to control. If no damage to wires and all connectors okay, proceed to step C.
3. Repeat steps A and B for door switch.

3. Measure door switch (door open = switch open small low voltage terminals). Replace switch if defective.
4. Measure latch switch (unlatch = switch open, CAUTION - oven light contacts are closed). Replace switch if defective.
5. If corrections are made in any step, reconnect power to control. Press and hold any key for 1 minute to clear R failure code from memory. F2 will appear. Press CANCEL and observe for 1 minute to ensure operation is correct.
6. If failure remains, disconnect power and replace control.

try powering the unit down for 15 minutes at the unit or circuit breaker,then power it back up and see if it clears these codes,then if not replace the e.c.u.(electronic control unit) and keypad

Hi

Error E1 F5 means that the control has detected a problem with door latch switch. Switch off the power and unplug it from the mains. Check after 5-6 minutes whether the error has disappeared. If the error is still there then once again start the self clean cycle. Press the self-clean button to start the cycle. The panel becomes blank (---), then press the up arrow (^). The panel will appear 3:00 (indication for the duration of self-cleaning). The oven will lock on its own and start the self-cleaning. After self cleaning is done wait for 15-20 minutes and open the door. Try moving the latch manually to unlock it. hope this helps...

HI. This is essentially a board code(EEPROM check-sum error). Use this check procedure to confirm failure.

1. Safely disconnect the power from the affected unit for five minutes.(Shut of the appropriate circuit breaker or unplug from the wall)
2. Re-apply power and observe for at least one minute.
3. If the code re-appears, replace the main control board (also called ERC or clock).

Unplug the unit or shut off the circuit breaker for 5 minutes. Plug the unit back in or turn on the circuit breaker. Set the clock and gently try moving the door lock lever (is so equipped) or opening the door.
or
Set the self-clean cycle again and only allow it to work for 15 minutes. Cancel the self-clean cycle and allow the oven to cool. Gently try moving the door lock lever (is so equipped) or opening the door.
If these procedures fail to correct the condition, the lock must usually be accessed and moved manually to open the door.
Some model ovens require the oven door to be manually unlatched before the controls are returned to the OFF position or else the door may not be able to be unlocked. Check the owner's manual for proper operating procedures.
