Buttons will not work

The PF is a power failure code and it indicates the control is not sensing any line voltage
Check the circuit breaker for the dryer is not tripped. The PF could be caused by a voltage drop during a storm but you should be able to clear it and run the dryer

As you probably know the PF code indicates Power Failure has occurred! To reset press the ON/OFF buttons, then make sure the time is set correctly! Should be good then!

Do the buttons beep when pressed if so bad control do know the model number the keypad and control might all be in one the PF is normal indicated Power Failure

The "PF" on any appliance indicates a power failure. So if you lost power in a recent storm, this would cause your problem. Pressing the cancel button should clear up your problem, and put you back in business. If not, unplug the unit, plug it back in and try the cancel button again. If trouble persists, your board is probably at fault.

The problem is on the control panel, which can be repaired economically.

There is a a YouTube video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

The lights can can be inoperable or stuck on or stuck in "night light" mode. Sometimes this will similarly affect the fan operation or inside light, too.

"PF" CODE USUALLY INDICATES A POWER FAILURE CLEAR CONTROL PANEL---RESET, CLOCK, OR TIMERS AND SET TO BAKE 350' IF EVERYTHING RESPONDS O.K. YOUR LIGHTS MAY HAVE BLINKED OR SOME OTHER POWER INTERUPTION

"PF" indicates the electronic control detected a Power Failure.
This could have been caused a brief power outage OR may be an indication that the connections to the oven, either at the stove or at the plug are loose.

Replace the clock.
