Circuit Breaker

One of the first things you want to check is the circuit breaker. A circuit breaker may simply have tripped and cut off power to the thermostat. Go to the circuit breaker box and see if there are any tripped. If so, reset them and go back to check the thermostat. It may be on as simple as that!

Dead Batteries

Did you know batteries typically power a thermostat? The thermostat may have dead batteries. While older thermostats are hardwired, the new ones are not.
