Thank you for your question.
I can understand wanting to know why you keep getting the PF code on your range.
The PF code indicates loss of power to the range.
It sounds like you are either getting an interruption of power to the range or there is a loose connection at the outlet and is causing the PF code.
I would suggest check to see if the outlet behind the range is secure.
It would seem unlikely that you would have that many power outages.
