Zanussi double oven switches off during cooking. It can be restarted without a problem so fault can not be detected. It displayed error 3 message once.

An F9 error code on a General Electric (GE) oven indicates that the oven's electronic control system has detected a problem with the automatic door lock. The automatic door lock mechanism prevents the oven door from being opened when the oven is set for "Clean" mode. The malfunction may be a jammed door lock mechanism, a pinched or broken wire, a faulty lock switch or a fault in the control board itself

Check your power loose connection. No.# 1 cause of EOC board failing may be in ground return to power hook up

Here is Frigidaire's suggestion to your problem:

Oven Control Beeps

and Displays an "F"

Error Code

Electronic control has detected a fault condition. Push CANCEL pad to clear the display

and stop the display from beeping. Reprogram the oven. If a fault reoccurs, record the fault
number, push the CANCEL pad and contact an authorized servicer.

It's an error code that will not go away until a technician resets it. Quote straight from the manual :

"The oven may detect a fault during programming or during operation. If a fault is
detected, the message "Fault detected - press power to clear" or "Fault detected -
press enter to try again" may appear. Follow directions in the display. If the fault
reappears or does not clear, call an authorized servicer or the toll-free number in the
display.
• If the same operation is attempted before having the wall oven repaired, the message
"Feature not available" will appear. The feature will remain inoperable until service
is obtained":

F3: Magnetron Current Low

Fault is displayed when the current transformer

(CT) on the I/O control board does not detect

enough current. The fault is monitored when the

microwave is on during a cook cycle or self-test.

The fault is cleared from the display at the onset of

a cook cycle if the CT detects current or when the
magnetron is successfully energized in Test Mode

This code is displayed when the user attempts to restart the appliance after an
error code 001 or 002

Hello,F9 error means there is a problem with the lock switch.Check the wiring to the door lock switch (the wire harness may be connected wrongly).Check for stuck lock switch.
Thanks

Hi. Has a fault code been displayed and a continuous beeps? press and hold the cancel & cook & hold buttons together for about 3seconds then door should open.
Hope this helps.

there is a casing stat which senses overheat. this can be due to lack of ventilation if a built-in type or a fault with the fan
