Hi F3/F4 error in your GE microwave
means that the keypad/touchpad is bad and should be replaced. However, before
replacing it you can follow these step by step instructions to clean the
touchpad assembly and see if it works: 1) Unplug microwave 8) After this put the keypad back
if its not solved then replace it. Hope this helps...please post back
for further assistance. Daniel
2) Remove two small screws from upper face plate
3) Remove screw on upper side of control panel
4) Life panel and pull out
5) Identify flat tape-like harness connecting
circuit card to keypad
6) Wipe down harness with an all-purpose wipe
7) Use hairdryer to dry remaining leftover moisture
It sounds like the magnetron may have
either failed or is not being supplied with the extremely high
voltage required to run it.
YOUR
SAFETY IS PARRAMOUNT
This is a job for a professional but if
you are safety clued up, here's instruction.
Make sure the
!!!!capacitor is discharged!!!!! before attempting any
sort of repair.
Check the door interlock switches first then the
high voltage diode with either an AVO model 8 or moving coil meter on
high resistance range for short circuit, (DVM's won't show the
fault!), the capacitor can fail and go short circuit, the feed fuse
on the primary of the high voltage transformer and then finally, the
magnetron is best checked by substitution.
Hope that helps.
