Replacing thermostat on miele T430 tumble drier

i don't know. first guess is regular drying cycle makes predetermined heat levels and sensor that shuts off heat and dryer when it decides clothes are dry. 20/40 minute
choices may be fan only unless there is a manual temperature control that you can set eg. off/low/med/high..

Clean all filters on machine this will sort the problem out .

Which model?

could be thermal limiter fuse in the back of the dryer. this can cause it to not heat but still the drum will turn

If the rug was very heavy you could have burnt up the motor. If it will restart after it cools off, replace the motor and clean out the vent system.

Good luck.
