When I put dryer on 140 min cycle it will work for about 30 mins then stop, I press restart and it will go for 10 mins and stop and so on, however, if I then put it at 80 mins it will continue until end of cycle. I dont think its overheating, I have cleaned all filters and condenser unit, could it be the time switch thingy?
