We have a speed cook microwave that showed the F3 code about a month ago, so we looked on your forums and noted some of the feedback. We sprayed down the control boards with electronic parts cleaner and it fixed the problem for about 2 weeks. Now it is completely DEAD. No power to it at all.
Can you suggest our next move to fix the problem and have a microwave that works again?

Regards

I am hoping that someone out there can get back to me today and help me determine what might be the cause of my DEAD microwave.

When we were getting the F3 code the power still worked even though the key pad was not working, but now there is no power.

Fuse? Board? What can I try?

PLEASE HELP!

:confused:

The "F3" error code means a shorted key panel.

Inside the control panel suppose to be a wiring diagram which should help you to diagnose the power failure. Besides the line fuse there are two more thermal fuses - one to control the magnetron temperature and another one to control the cavity temperature.

- The part number for the key PCB assembly is AP3792788

- The part number for the inline fuse is AP2631556
