Can you give a approximate temperature the the thermostat should operate at & does it activate the timer at the same point that it deactivates the heater?Bob
Already Tried: Build up of fluff on the thermostat removed, but running an empty load still does not result in the timer advancing on the Auto mode.
Hello BobThanks for using JA
There is normally about a 11-15 degree differential on an operating thermostat, more on a high-limit t-stat'So look at the numbers on the thermostat. The stated number like L120 is the cutoff point 120-15=105 cut-in
If the thermostat does not cut out the timer will not run. Check your air flow thru the vent. Take off the vent pipe and see if the timer advances
Any other issues just come back hereor if thats all you need please rate my question for my helpThanksDon

Don, Thermostat is L150 which I assume is Farenheit. Digital probe thermometer in the air flow indicates76C or 168F at min for heater off/timer on. Then about 60C back on. Sounds too high for a decent cycle of the timer?Bob
Should turn off the heat at 150-155 then go back on around 130-135Thats what I normally find on your model.Check all the felt seals around the drum. If you cold are leaking INTO the drum the thermostat will not function properly. The thermostat just will not trip.
