If there is a power failure to the electrical supply to your home, when the power comes back on, you may see a "PF", "888" or "8888" code in the display on your Microwave Oven. Depending upon the model, one of these codes will appear in the display to indicate that the power failure has occurred.
Okay - so PF is Power Failure - try a reboot first to see if you can clear the PF from the display. UNPLUG microwave from outlet - or shut off breaker to outlet - for 1 minute - plug back in or turn breaker back on and if PF clears then it was just a reset that was needed.
Reset the microwave: Sometimes, a simple reset can resolve minor issues. Unplug the microwave from the power outlet, wait for a few minutes, and then plug it back in. This action may reset the internal electronics and fix any temporary glitches.
A PF (Power Failure) error code indicates that the wash cycle was interrupted by a power failure. Touch and hold START to restart the washer cycle or press POWER to clear the display.

Depending on your GE microwave model, you will either see a 'PF', '888' or '8888' error code - these all carry the same meaning but can all be dismissed and cleared by simply pressing 'CLEAR' or 'OFF' on the control panel touchpad.
Possible Solutions
The oven will display “PF” when it is powered up for the first time or has experienced a power failure. It can be cleared by pushing cancel or interacting with any button or knob. If a cooking function was in process, dispose of food; it might not be thoroughly cooked.
If the washing machine is installed in a humid environment (bathroom, etc.), the PE error may be displayed as a result of excess moisture. In such a case, disconnect the power plug, connect the power plug again 5 minutes later and operate the washing machine.
Keep the microwave unplugged for 5-10 minutes. The waiting period allows the internal components of the microwave to reset, ensuring a clean slate when you plug the microwave back in and reprogram your desired settings. Check for any evidence of damage on the plug and outlet before plugging them back in.
There has been a power failure or the clock time has been turned off. When power is first supplied to the microwave oven, a colon ( : ) will blink in the display. Touch the "Cancel/Off" or "Cancel" key (depending upon model) to stop the blinking.
If the cost of repairing a microwave comes close to or exceeds the price of a new one, it might make more financial sense to replace it. However, if the costs of repairing are relatively low and the microwave isn't too old, it could be worth repairing the microwave.
PF indicates a power failure. This is the normal indication if the power to the unit is cut, and then restored, as would happen during a lightening storm, or other power failure that is restored at the switching station. To resolve this unplug the unit for a few minuets and plug it back in.
To clear the error code from your microwave: Unplug the unit from the wall outlet or trip the circuit breaker to cut power supply to the machine. Allow the machine to remain unplugged for 10-15 seconds. Restore power to the unit.
If the PF error is due to a brief power outage in your home, fixing the issue should be extremely simple. Try pressing the “off” button on your touchpad, or the “clear” button. If the error code immediately clears, you can resume using your microwave again as normal.
Unplug the dryer from the power outlet. Let the dryer remain unplugged for at least 2-5 minutes. Plug the dryer back into the power outlet and turn it on. See if the PF error has disappeared from the dryer's display.
For most electric ovens, you can try a general reset by disconnecting the oven from power for a few minutes and then reconnecting it. This simple trick can often resolve any issues caused by the power outage. Give it a try and see if your oven springs back to life!

Misset functions or broken parts are often to blame when your microwave is not heating up. Settings like Control Lock Mode, Demo Mode or power levels set too low may be preventing food from cooking, or more complex causes like a broken magnetron, door switch or high voltage diode could be the source of the problem.
