bpenny added a question in WorkshopTruma Ultraheat staying onHi
The Ultraheat electrical heater in my van has stopped responding to the thermostat. It used switch on and off correctly but now just stays on. Yes, could be worse, but I'd like to fix it. I've replaced the control knob switch and thermostat combo control, but the problem remains. Any ideas, or preferably, experience with the same problem?
