F3 on a GE / Hotpoint microwave means you have a shorted membrane keypad.

If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

On some GE models, the membrane keypad is not available as a separate part, so you would have to order the control panel frame assembly which comes with a new keypad.

If you would like to have us do this repair for you, we do that for $39.95 plus part costs nationwide.

Feel free to contact me via our site (and please mention your full model number from the tag on the unit) for more information & help.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

My microwave keeps beeping when plugged in and shows a F3 code on the screen. What can be done for this?


Possibly a sensor error.
There is a temperature sensor that is giving the wrong voltage to the control panel.

While cleaning it the vent began to open and close and the microwave would not shut the vent down when the keypad was used to end the cycle. Now it only shows F3 on its screen when we try to set it up...


The "F3" error code means "Shorted key panel (touch pad)". The correction is to replace the key panel aka a membrane switch or a touch pad. The control panel in that case is just a plastic frame.

It shows f3 in the screen


This code will occur if a shorted key panel is detected continuously over 60 seconds. Replace key panel (also called touch pad).

Spacemaker beeping loud and f3 message driving us crazy


The error code F3 indicates an oven sensor problem. The oven sensor is most likely the failed part. The oven sensor probe must have the correct resistance readings at specific temperatures. When the electronic range control (ERC) cannot identify the correct resistance of the oven sensor or the resistance is way out of specs F3 will display.
I recommend calling a service technician to diagnose and repair your oven.

On the screen it shows F4, and F3


F4 means an open humidity sensor, but sometimes this error is bogus and can be reset by unplugging the oven for a minute or so.

F3 on a GE / Hotpoint microwave means you have a shorted keypad.

If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

If you would like to have us do this for you, we do that for $39.95 plus part costs.

Feel free to contact me directly (and please remind me of your model number) for more information & help.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Microwave shows F3


microwave quits working and F3 comes up on the readout - along with a series of beeps - pressing any of the buttons on the touchpad does nothing - The F3 stays there and beeps intermittently

Micro beeps 3 times with "F3" flashing on LCD screen. Nothing works.


If it's a GE model, F3 will mean a shorted key panel.

(If it's not a GE, please reply back with your brand and model number so we can help you).
