If you continue to receive the PF error code, the control board may need to be replaced

Hello & Welcome to FixYa

PF error means power failure which is generally caused when the control board inside the unit goes bad. You can try unplugging the unit for 15-30 minutes, if the issue returns then the control board needs replacement. Please get back to me if you have any other questions.

The PF on your control indicates a power failure and should be removed by pressing the cancel button. The 5ab code indicates the range is in the SABBATH mode.

If a power failure occurs when the SABBATH mode is set, the oven will return to the OFF mode and will turn the power OFF to the oven.

To ENABLE SABBATH mode:

* Open the oven door
* Press STOP/CLEAR
* Press both the HOUR "UP" and "DOWN" arrow pad at the same time - and hold for 5 seconds.
SAB ON will disappear from the display.

To disable SABBATH mode: Repeat the steps above and SAB OFF will appear.



To set the SABBATH mode for use during the SABBATH/Holidays:
* Press BAKE
* Pres TEMP "UP" and "DOWN" Arrow pad to enter a different temperature other than 350 degrees. (Between 170F and 500F)
* Press COOK TIME
* Press HOUR/MIN "up" or "down" arrow to set cook time
* Press DELAY START to set a delayed cook time (optional)
* Press and hold TIMER OFF for 5 seconds
SAB will appear on the display indicating it is ready.

PF simply means power failure, not really a fault as much as a visual indicator to let you know that you've experienced one. i would check your electrical outlet,sounds like a loose connection

Seen This before Main control board fixed it It would go through most of the wash cycle and just quit no errors but PF
