Since new, the console Temperature Switch has to be turned to a lower position than should be necessary for the type of drying required. Even then, sometimes the items get way too hot.
I'm assuming either the Temperature Switch is not sending the correct signal, or the Thermostat is bad. The only reason I don't think it's the Thermostat is the temperature fluctuation seems controlled.
What do you think might be the problem?? What is the part number for the needed item??
