My furnace runs and blows heat until the desired temperature is reached, but then it will stay off until the house cools another 15-20 degrees before kicking back on. What to do?
First , make sure thermostat is level on the wall. If o.k. try adjusting the anticipator at the thermostat. remove cover and you should see same as in picture. Move arm away from longer slightly, and try it a few times, each time before going more. If that doesn't help, it may be time for a new thermostat.
