When does a / C shut off when set temp?
When does a / C shut off when set temp? Except that it doesn't stop running when it gets to the set temp. Thanks again for any help or insight the community might have. Why does my a / C keep turning on and off? That's attached to a bimetallic strip (coil of wire), when it tilts enough, the mercury rolls to the other side of the switch, making contact. This turns your 'appliance' on or off (heating, cooling). You should be able to activate this by hand (gently push it). Can you see something wrong here? What to do...
