You need a new control board. not hard to repair but it be about even to get a new unit... take it to a repair shop and will be more than a new microwave and use a a small surge protector for the microwave. cheaper than a new ckt, board next time.
F3 on a GE / Hotpoint
microwave means you have a shorted membrane keypad (aka membrane switch).
If and when an oven is coming on or doing anything by
itself, this is very dangerous and can result in a fire.
So until it is repaired,
please leave it unplugged or leave the door
open when it's not in use, and of course one should never leave a microwave unattended while cooking.

know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically

That error means the oven sensor is open. You can test it with an ohm-meter. Then it is either the oven sensor that needs replacement or the control board itself, even if its both replacing them yourself should be cheaper then a repair call. Thanks, Lee
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.
I had the same problem. I removed the grill and opened the control panel as I read an answer from "GENE" on APP (Appliance Pros) that this indicated a short in the circuit board (TouchPad). I was going to replace the faulty circuit board but when I opened the control panel there it was......One wire harness had just came unplugged!! I plugged it in, reassembled and the microwave works again!
