Hi when this occurs it is usually a fault on the I squared bus? and is also usually associated with a microprocessor problem too. it is NOT DIYable. Accordingly it needs to be repaired, this should only be done by a professional. To this end what you should do to get the best possible results, is to contact the manufacturers local or head office, and ask them for a referral to an authorised service center, then take the unit there and when in face to face contact simply ONLY ask for a "Quote" as to prospective costings, and go from there, this way you can at least make up your mind as to repair or replace?

Error code e1 f2



1.
Check keypad connector for firm connection (keypad connects to control
board).
2. Press CANCEL. If error code returns after 60 seconds, replace
keypad (also called touch pad or membrane switch). Some models incorporate
keypad in to control board as one unit. In this case, replace control board
(also called ERC or clock).

Microwave Oven

I report from owner manual.

F3 means : Short circuit on key panel (your touch pad).
You get F3 error if a shorted key panel is detected for more than 60 seconds.
Solution: . Replace key panel (touch pad).

Try first unpluggign power cord for five minutes.

If you think that the problem may had been caused by water inside the keypad you can try using an hairdryer on the keypad, taking care not to melt the keypad plastic.
If that does not work, then replace the keypad.

You can buy replacements here. or Order GE Microwave Ovens Parts Here
