Whirlpool Duet Dryer PF error

[Gomotomoto]

I have a GGW9250PW1 Whirlpool Duet Dryer giving me a PF code. I replaced the thermistor (which tested faulty with OM meter) with a new one and still getting the PF meter. I also tested continuity of the fuse located right next to it and it's fine. 

Any idea what else it might be? If it's a whole control board, I might just start with a new dryer. Thanks and any help appreciated before I spend $800. 

Thank you!

Press cancel on the interface panel to clear out the code.  you could possibly be having an electrical issue  with the L1  or Neutral line going to the dryer , There is also a belt switch connected to the motor cradle that may be acting up also.   I would first try and get a good extension cord and plug that into a different  outlet and breaker line than the one its presently plugged into.  Then plug the dryer into that  cords power source.  Run the dryer to see if the error code issue goes away. if it does then you know there is a problem with that outlet its been plugged into.  If the error code does come back up again then that would mean the issue will be with the dryer and a possible electrical issue with the dryer itself.  this way at least you can eliminate the dryers input power from the wall receptacle back to that outlets breaker in the panel as being the problem.   As I mentioned its possible your losing the power source some where
