Question about Dryers
I've looked up the PF code on this site and people say simple power failure. Most people who explain the problem say this trips the breaker. Mine is not tripping my breaker. It happens when I use timed dry over 30 minutes.
The support guy came out, replaced the control board....did not check temp sensors or anything else. Said if the control board didn't fix it, it would be time to call electrician. I think it's an issue with the dryer. The grate on the back of the dyer (the silver one) looks rusted or scorched and I've had temp issues before. Like I said, it's not tripping the breaker either, the machine is resetting itself. Any ideas?
After ranting and raving about similar issues with my own Whirlpool Sport, with no success from a ton of repairs and technicians, I decided to check the exhaust vent from dryer to outside - thinking that the dryer must be sensing an overheating problem to trigger internal shutdowns without tripping the house breaker. Sure enough the vent flap on the outside of the house had become stuck, instead of flipping open when the dryer is working. I fixed the vent flap and the problem was solved. So check all aspects of the venting - a squashed flex hose, stuck or partially closed vent flap, something covering the vent. Sometimes the simplest solutions are the correct ones.

We just had the same problem. have your power company come out and check for a neutral ground problem coming into the house. I know it sounds silly but the machine needs full power. Our machine started doing the same thing the other day. I called the power company and they came out and checked the neutral ground and there was a connectivity problem. the machine would just go to PF during cycle changes. this solved the problem. Had these units for 3 years and this is the first problem but we just moved into a newer house and there you go.

Two technicians have been out (new guy & experienced guy). First tech didn't take lower panel off, but 2nd tech did and found that drying vent tube (4" tubing) had disconnected. I replaced the rigid vent that came with it to vent to the left side instead of the back. That was 6/3 and today is 6/6 and it hasn't happened since. It was happening every load where it would run 3 minutes and shut off, then cool off for 5 minutes, run for 3 ....
Check you vent tube. I'll post again if this turns out not to be the solution.

Yea i would reccomend having a Qualiified Whirlpool tech come out and have a look at that one. PF is def an indication as to a power failure. although ive ***** seen this particular problem on this particular unit.A call to the tech assistance line by the service guy while in home should prove quite helpful.
