Signs Your Programmable Thermostat Is Broken

Before calling GAC to replace your thermostat it is important to perform a couple tests to determine if your thermostat is the cause of your HVAC troubles, or if another piece of equipment may be malfunctioning. To determine if your thermostat is broken:

  • Set your thermostat five degrees higher or lower than your normal setting (depending on the season). If your HVAC system does not turn on after raising or lowering your setting, your thermostat may be broken.
  • Check the setting of your thermostat. Make sure the thermostat is set to “cool” during the summer and “heat” during the winter. An accidental bump from a passerby may have changed the thermostat from your desired thermostat.
  • Check wire connectivity inside the thermostat. To do this, turn off all power to your HVAC system by turning the appropriate breaker to the off position. Then, gently remove the cover to your thermostat and check that all wires are attached and tightly fastened.

If your programmable thermostat is still not working after these DIY tests, contact GAC Services. Our licensed HVAC technicians will diagnose and repair—or replace, if needed—your thermostat and get your system back online as quickly as possible.
