The next winter it didn’t work and under warranty, it was changed again, and the tech said he changed the limits on when heat would come on and go off. Since he did, the heat doesn’t come on until it gets pretty cold in the house (when set close to 70, it wont come on at 68° and it should), and when it does, usually in the middle of the night/early morning, it runs from 17-23 minutes, so either the blower or getting too hot wakes us up. This is wasting my oil and making us too hot, as it goes to 74 or 75 degrees, when I have it set on 69 or 70. I want to know what that is called and how to change my limits back. My furnace didn’t do this until he changed the limits and I shouldn’t have to pay for the company to fix what they did, and for no reason that I was told.
