GE JVM1190 control pad

see the commentaries and repair:
F3--Shorted key panel(touch pad), will occur if a shorted key panel is detected continuously over 60 seconds.
test the following:
1. Door is not closed (some models).
2. You waited to long (open and close door to wake it up).
3. Controller is confused (pull plug for a minute or two to reset).
4. Defective interlock switches.
5. Faulty controller or its power supply.
6. Touchpad or controller board contaminated by overenthusiastic cleaning.
7. Defective/damaged touchpad.

Hello,
The F3 code means that the Key panel also called touch pad is shorted. This code usually comes up when when the Microwave detects the shorted panel continuously for over 60seconds.

To correct this error, you have to Replace the key panel also called the touch pad.

Thanks.

F3 Shorted key panel (touch pad).
1. Will occur if a shorted key panel is detected continuously over 60 seconds.
2. Replace key panel (touch pad).
What you can first try before replacing the keypad is first unplugging the microwave. Then you can get access to the panel by first removing the top grill and then unscrew the top of the control panel. There is a strip that looks like tape which attaches to the control panel which you need to wipe off and then blow dry. may not work the first time but be patient. also clean the bottom of the door and the latches to make sure the connection is clean. After that is should hopefully work without replacing the touch pad.

Let me know how this works out for you.

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 have a blown actuator. This is the device that creates the microwaves that cook the food. The cost of one of these will be as much as a new unit.
