Why Is My Thermostat Not Getting Power?

The good news is that thermostat problems are often easy to resolve. Follow these four easy steps to troubleshoot a thermostat not getting power.

  1. Make sure the thermostat is turned on.
    It’s always a good idea to start every troubleshooting process with the simplest solution, so verify that the thermostat’s power switch is on. Many thermostats are easy to accidentally turn off during routine dusting. Maybe someone else in the house turned the unit off without mentioning it to the rest of the family. If the weather has been nice and your HVAC system has been off for a while, you may simply forget to turn the thermostat back on before trying to adjust the temperature.
  2. Replace the batteries.
    If you have a battery-powered thermostat, try putting fresh batteries in the unit. Most people don’t keep track of when they replace their thermostat’s batteries. For best performance and complete peace of mind, replace these batteries at least every six months. An easy way to remember this task is to replace your thermostat and smoke detector batteries when Daylight Savings Time starts in the spring and ends in the fall.
  3. Check the circuit breaker panel.
    The next simplest solution for a thermostat that has no power is a tripped circuit breaker. This is a common cause for appliances, power outlets, and HVAC equipment not working. Open your electrical panel and look for a switch that is not aligned with the rest. If you do see a misaligned switch, turn it off and then back on. Try turning the HVAC system back on to see if that resolved the problem.
  4. Open the thermostat housing and make sure it’s clean.
    Over the years, dust can build up inside your thermostat and prevent it from working correctly. If people smoke in your house, sticky tar build-up can make the situation even worse. Gently remove the thermostat cover and look inside. If there does appear to be gunk caked on the thermostat’s components, use canned air to carefully blow the dust and debris away.
