I checked my circuit breakers and they are fine. The 3-prong outlet works and is fine. My dryer runs and runs and never gets hot and never turns off. It has to be shut off manually. I have replaced the following
and cleaned out all lint from everywhere. Am I missing something? Please help.
AP3094244 (279816) - Thermal cut-off for dryer heating element 309 degrees (includes high-limit thermostat)
AP3132867 (3392519) - Thermal fuse (disposable, one time fuse)
AP3131941 (3977767) - Thermostat, fixed
AP3094254 (279838) - Dryer heating element
AP3131939 (3387134) - Dryer cycling thermostat, L155-25

Try starting the dryer on the time cycle around let,s say the 30 min mark. While running hold the timer knob and press in down or up holding it there for a few minutes open the door a check to see if there is heat . If so you will need a timer. good luck.

Mell you check almost everthing on the dryer,but this going to sound funny but the trouble could be in the motor.The motor has a centrifugal switch on it.This switch consists of one single-pole double-throw[spdt]and a single-pole single-throw switch.What could be happening is the [spst] switch may be opened.Normally when the motor is up to speed,the[spst]switch closes a separate power circuit to the dryer heating element. To check this there should be continuity between terminals 4 and 5 and between 2 and 3. ..GOOD LUCK.

OH YOU MEAN READINGS FOR THE CENTRIFUGAL SWITCH infinity would be good...lol NOW if your testing the motor protector in the centrifugal switch[2 to 4.5 ohms lets say +/-10% across terminals1 and 4 does this sound ok...

You will need to jam a flat bladed screwdriver to activate the centrifical switch. Jam it between the housing and the black plastic ring in the motor.Then test the switch pins 1-2, should be a red dot for both on the switch.
We all depend on meter data for these electrical items, without it we are left helpless.

Yes that's what you can do, but I find it easier to just move the internal motor centrifical switch black washer over, thus activating the switch.
