your anwser to pete,regarding the thermal cut off kit is wrong.part #279816 does not contain the correct parts for a mod#wed6200swo the lower piece is part#ap3951297 which is listed separate, from the cutoff kit..i was sent the wrong parts #279816 and got the same results as pete,with 1 exception,i twisted the 2 red wires together,and the dryer seems to be working normally.this modelwed6200swo uses a thermal cut-off on the top of the heat duct,and a inlet thermistor/high limit thermoastat in the lower part of the duct.its mounted in the element housing.the lower cutoff supplied with kit 279816 has no provision for the 2 smaller ga .red . wires.this wil f lash a code to replace other parts,but its because you have the wrong parts ,the lowercutoff, installed.if pete orders part #ap3951297 and installs it in the lower position all should be good. or at least im hoping so because i am in the same dilema, do i need to order more parts??? as in ap3951297???

Maytag Serial#mu500-4010 Dryer getting warm during cycle, but will not get as hot as it should. Will have to run a load more than normal ranges. Please advise if the element or the fuse would be first place to start?

Recieved the thermal Dryer cut off kit # ap3094244. it looks a little different as it does not have the plug for the two red wire harness that went on the old part, # 8577891.. there was also a new part that I placed on the upper setion ot the heating duct. Pugged it in and nothing happened. When pressing the start button, the sensing light on the panel lights up and nothing else happens. While I was out here on the pc, the dryer signaled it was done, and beeped. It was not runing an must have timed out? Anyway, I found the diagnostic sheet and managed to pull some codes: F-23, F-25 and C-5. Checked the Exhaust Thermister, no resistance, same with the Inlet Thermister. Very strange. Checked the P4-3 and P4-6 terminals and the reading was 13.8k Ohms. This tells me to replace the Machine Control Electronics. What is the next step? Help. Tired of going to the laundrymat. Thanks.

We did a load of drying good, and then tried to restart another load and the power on the board comes on but it will not start? Did a diagositic check and it says code F-25 which says its the "inlet Thermistor"? Can that just go out like that with no other warnings?

I checked each element terminal to the casing and there is no short. I checked the heater relay between N.O.Black and COM Red and that circuit is open.(The N.O.Black connector shows signs of overheating.) I checked the inlet thermistor at P4 pin 1 and P4 pin 2 and found 48800 ohms. I also found a Service Tech Sheet when I opened the Machine Control Electronics. Under "Heat will not shut off" troubleshooting, it refers to P4 pin 3 and P4 pin 6 at the connector.(disconnected.) My reading is 9k to 10k ohms. It suggest that I replace the machine control electronics with a reading between 5k and 15k ohms. Do You agree?

I am blowing thermal fuses, When the dryer runs with the back off I can see the the heater coils glow red, but do not cycle off. I have changed AP3951297 (8577891) THRMST-FIX, but this does not help. I get continuity on main spade terminals and when using a lighter the circuit will open. I have also checked the Dryer thermister, it has about 8.5k to 10k ohms at about 79 Deg. When I put my fingers on the sensor the resistance drops quickly.I have also pulled out the heater element to make sure it is not sagging or grounded.
