How To Troubleshoot A Programmable Thermostat

A programmable thermostat is a sensitive piece of machinery. You count on them to provide perfect comfort for you and your family around the clock, all year long. They automatically adjust the temperature based on the settings you implement. But, sometimes things go wrong. Get in touch with our team to learn more about programmable thermostats.

Power Problems

The first thing you’ll want to check is whether there might be a power supply issue. If the digital display is off or has been flickering, try these troubleshooting tips for your programmable thermostat:

  • Has the circuit breaker been tripped? Check your circuit panel to see if any breakers have been tripped, and reset it.
  • Does it run on batteries? Remove the front cover and check if there is a battery present. If so, replacing it with the appropriate battery may solve your issue.
  • A fuse could also be blown. Thermostats sometimes contain a fuse. Remove the front cover and check the filament in the fuse. If it’s separated, remove the fuse and replace it with a matching fuse.
  • Consult your owner’s manual if you believe a wire may no longer be making contact. You’ll need to remove the programmable thermostat from the wall mounting.

If you’re uncomfortable or don’t feel safe with any of these troubleshooting options, just give us a call.

Settings & Mode Problems

The next thing you may want to check if the programmable thermostat isn’t running properly or won’t stay at the temperature you set, is to check the settings and modes:

  • Whichever mode you are trying to use, attempt to use the opposite mode to see if the HVAC system will kick in. So, switch from heating to cooling, or cooling to heating. Also, attempt to use the auto setting after some time to see if it also works. If they do, then you’ve isolated the problem to just one setting.
  • There may be a red or “emergency” indicator on your programmable thermostat. Be sure to check your owner’s manual to learn what this indicator might mean.
