About This Part
The thermostat monitors temperature and switches heating or cooling to hold it steady. When it drifts or fails you’ll see overheating, no heat, or cycles cutting out early. A new thermostat restores accurate temperature control.
Many owners fit this themselves; if you’d rather not, any local repairer can fit the part you supply.
