How to Troubleshoot Your Thermostat That’s Not Keeping Its Schedule

The thermostat that controls your HVAC system could be described as the brain for your heating and cooling. Without those temperature settings, your HVAC won’t know what you want it to do. So whether your thermostat is an old-school mercury/analog model, a simple digital type, or a newer programmable thermostat, or even the latest and greatest Wifi thermostat, you need it to work right so you can set it, leave home and trust that the system will go on and off as you need it to.

Here’s some advice on thermostat troubleshooting:

Thermostat Troubleshooting

Thermostats, like everything else, don’t last forever. Within four to five years, no matter what type you have, it may be time for replacement. With that in mind, in the event of a malfunction, do undertake some minor troubleshooting to see if you can get it back on target before you schedule a replacement.

  1. Check the power source. First, check the circuit breaker to make sure the power is on. Then, for all thermostat types except the analog, check the battery, fuse or wiring. If the unit is battery operated, replace batteries and see if the readout comes on. Likewise with a fuse. If the thermostat is wired in, check wires to make sure they are not loose or worn. You may have to replace wires, or else hire an electrician to do so. If you work on the thermostat yourself, be sure to flip the breaker so the power is off before you undertake any repairs.
  2. Clean it up. You’d be surprised how dirt and dust can interfere with the workings of a thermostat. Open up the thermostat and check for dust, dirt, pet hair and spider webs which might interrupted the electrical function of the device.
  3. Move the thermostat. Sometimes a thermostat doesn’t work properly because it’s in the wrong location. It should never be where a cold draft or sunlight can hit it. Have it moved so it will work properly.
