How to Troubleshoot My Thermostat
A thermostat is a heat-activated switch. It has a temperature sensor that causes the switch to open or close which in turn completes or disrupts the electrical circuit that runs your heating and cooling system.
Always the first thing to check if your HVAC system is not working, is your thermostat.
Things to check
- Is the thermostat set to “On” and for the appropriate setting?
- Does it need new batteries?
- Is it a programmable thermostat? If it is confirm that the overrides or settings are not programmed to an operation counter to what you are trying to do.
- Is it excessively dirty? Dust and dirt and other indoor pollutants can clog the thermostat. They can coat the inside and interfere with both electrical and mechanical components of the thermostat. Use a small brush, like a paintbrush, or a can of air cleaner for electronics, and bush or blow away the dust from the inside.
- Shift the anticipator one way or the other to cause your furnace to click on or off. Have a friend listen at the furnace as you adjust the settings to hear when the unit turns on and off. When adjusting the settings, wait and hour or two for results before consulting a technician for further help.
