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.
Try resetting the microwave by unplugging it for a few minutes and then plugging it back in. If you are comfortable working with appliances, you can check internal components like the fuse or thermal fuse. If these are blown, they will need to be replaced. Note: Always unplug the microwave before opening it.
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.
The PF error code means there was a power failure. This may have been caused by a power outage or a power spike. You can usually resolve this error by pressing the Cancel or Clear button. Or you can reset the oven by switching it off at the circuit breaker and waiting one minute before turning it back on.
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.
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.
One of the more common causes of microwaves not heating up is a faulty magnetron. This is what generates all those microwaves in the first place. If this burns out, or there is an electrical fault in the machine.
PF indicates power failure: First leave the unit unplugged for about 30 minutes as this will help to reset the unit. If it still doesn't work, then you need to make sure that the plug the dryer is plugged into is a good 240 current, as it may not be getting enough voltage to run the dryer.
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.
* Fuse blows when microwave shuts off (during or at end of cook cycle). * Oven heats on high setting regardless of power setting. * Oven immediately starts to cook when door is closed. * Oven heats but power seems low or erratic.
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.
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.
A PF (Power Failure) error code indicates that a power failure has interrupted the drying cycle. Touch and hold START to restart the dryer cycle or press POWER to clear the display.
To reset the microwave, unplug it or power cycle at the circuit breaker for 60 seconds.
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 your microwave isn't heating food, it's likely that the magnetron in your appliance is broken. Unfortunately, a burned-out magnetron can't be repaired, it has to be replaced. Other issues that can lead to food not being heated, includes a broken diode or a faulty door switch.
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.
PF means "power failure" and it has absolutely nothing to do with the thermistor. If you get a PF on your screen, it means that your control board attached to the left side panel of your dryer under the top panel is bad, or you're getting bad power from your house.
