- Turn off the power to the heater and A/C.
- Remove the cover.
- Obviously, change any batteries.
- Clean the bimetal coil with a soft, clean brush. On a round thermostat, you might have to turn the dial for complete access.
- Remove the body from the base on a round model. There are usually screws involved.
- Clean the switch contacts with a piece of bond paper.
- Replace the body on a round model.
- Adjust the anticipator. Start by finding and noting the amp setting; it may be in your manual, on the furnace service panel or on the boiler's transformer. Look at the anticipator setting on the scale. If it's off, adjust it with your fingernail; or you nail-biters (you know who you are), use the point on a pen.
NOTE: On an air heating distribution system set it to the amp setting. On a water heating distribution system set it to (amp setting X 1.4). I have no idea why. - Replace the cover.
