Hello, I have a Kenmore he3 electric dryer that runs for 1 minute and then displays f22. What does that code mean please? I have replaced the thermal fuse and thermistor and the dryer runs on air only, timed. When I put the dryer back together after replacing the rollers both front and back, I ended up with two red wires that I do not know where to connect it back to.

In the thermistor video, it says to put the red wire on the left and the black on the right. Why does this matter? Also, can a bad thermistor cause the thermal cutoff to fail? Thanks

Latest Questions

I have replaced the thermal fuse and the gas coils so far. However, when i try to run a load...the ignitor lights the gas...and within a minute or so the flame goes out. I get no reading of continuity on the Inernal Bias Thermister.....could that alone cause the burner to go out if everything else is ok? Or, maybe you could provide another clue to me where to look?

The whirlpool dryer works but does not dry the clothes? It first gave an error message of PF and I disconnected and started working but it does not dry?

The metal plate in the back of the dryer drum is getting very hot (190-210F). It also has a funny smell. I've disconnected the vent hose and airflow seems to be good. I've tested the themister and it has a resistance of 13.6k ohms at room temp and it varies down as it gets hotter. I've also verified the thermostat has 0 resistance when it's at room temp and the coils cycle on and off as it's running. Any idea what the trouble could be?
