Reasons Why the Thermostat May not Work

If your thermostat is having problems, whether it’s new or old, call us to help. Before jumping to the conclusion that your furnace is broken, know that it could be a malfunctioning thermostat, among other things, from heating and cooling systems that seem to have failed to an overworked system or duct work that needs attention. Most thermostat issues aren’t major issues so chances are, that caught early, it’s not going to be an emergency.

Check the power source. Your thermostat may just not be connected right or at all. A blown fuse, tripped circuit breaker or dead batteries will prevent the thermostat from turning on your furnace. Clean up any dust, dirt, spider webs and other debris. Any of these things can coat the inside of the thermostat and interfere with both electrical and mechanical functions of the thermostat. Put this on your get-ready-for-winter cleaning list. Just use a soft, clean brush to clean the inside components gently. Don’t get anything wet. Also you can use a can of compressed air, such as is used for electronics, to clear debris.

Check for any loose wires or terminal screws inside the thermostat. Make sure wires aren’t corroded or detached. Never remove the thermostat cover without removing the batteries or turning off the power at the fuse or breaker box. Tighten screws and secure loose wires if needed.
