My thermostat isn’t working?
If your heat doesn’t want to coming on at all, try replacing the batteries in the thermostat, if it has batteries. Also you may want to try giving the thermostat a good dusting inside with a small paintbrush.
We also recommend you try to reboot it. With the thermostat set to Heat, lower the temperature down to about 60º. Then, set the breaker switch off for 30 seconds and power it back up. Still not working? Call in an professional from Furnace Repair at (888) 320-3544.
