Please Help with Thermostat Question
We have a White-Rodgers 1F78-151 Programmable thermostat. We have the thermostat set for 72F. The temp in the house is 62F. The heat comes on but goes off before the programmed temp.
Something is causing the heat to go on and off but it always goes off before 72F. I've checked the date/time and they are correct.
Am I missing something? Shouldn't the heat run until the temp reaches 72F? Help would be greatly appreciated. Thanks all.
