Did you know that most new digital thermostats require batteries? If your thermostat’s batteries die, your heater will not run! Take a look at your thermostat screen and if it is blinking or has gone blank, your thermostat likely requires new batteries. Install fresh batteries and save a repair call! Older thermostats used power from the heating appliance and did not have batteries, so be battery aware and keep your home in comfort all winter long.
