PF = Power failure. Try and push the clear or cancel button (or start, or clock etc) You may have missed one. If that doesn't work try and unplug it for 10 seconds or so and retry.

One day the microwave just showed PF on the screen, unplugged and plugged in tried to use it, worked for 30 seconds, stopped and showed PF again. Any ideas? It is only a few years old and used in our...


PF is Power Failure. Check and see if the Oven has a reset switch or power button. Try and hook up an extension cord, plug one end into a usable output (wall plate) and the other into the 110VA line plug attached to the Oven. Turn on....if it works then the problem is a circuit breaker or wall interface. If it fails with the extension, then it is an electrical problem with the microwave device itself. If there are no Reset features on the oven, an internal fuse may blow, or other shorts are occurring. The cost to fix is more than a new unit. Lowes has them as low as $150.00.

My over the stove microwave flashes pf and none of the buttons work


You have a defective membrane keypad.

On some models, you can replace just the keypad itself.

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.

On other models, you can order a new control panel assembly, which comes with a new keypad already installed.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

You can find links to helpful exploded view diagrams and part ordering help here.

I recommend that you bookmark that link to your favorites.

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

Microwave does not work at all. Shows "PF" in display.


"PF" on the display is an indication that your oven experienced a power interruption. Normally, the error code can be cleared by pressing the CLEAR/OFF button. You may have to reset the time. This is accomplished by pressing the CLOCK button, entering the time on the keypad, then pressing CLOCK again. If this does not clear your problem, please let me know. I hope this helps you.

Have a PF and not one button works, even after holding e clear/off for three seonds......not one button works?


This is a keypad controller issue, behind it there is the microprocessor ic mounted on a board with several other components. The only way to fix this is replace the keypad along with the processor board and the cost would be more than a new microwave.

PF ?


Not actually dead, just apparently unresponsive.

PF means power failure. It either got reset or unplugged, etc.

If it's not responding to the keys, then you likely have a shorted keypad or trouble on the control board.

If you or a friend decide to look into it, we have critical information on safety, disassembly and door switches at our site, linked here on Fixya: http://tinyurl.com/yzjozk

Microwave won't work; timer word stuck on screen


The problem is almost certainly on the control panel, which we regularly repair nationwide for $39.95 postpaid.
