One of the best benefits of a programmable thermostat is that you can essentially “set it and forget it.” With summer’s arrival you probably switched your thermostat to air conditioning, double-checked the settings, and haven’t really thought about it since. The same goes for fall, when it’s time to turn it back to the heating setting. However, there are a few common problems that arise when it comes to programmable thermostats, and before you worry your entire HVAC system is malfunctioning, you can check and troubleshoot your thermostat first.

Troubleshooting Programmable Thermostat Problems

The most common programmable thermostat problems, and how to deal with them, include:

1. The system suddenly shuts off. If the display on the thermostat is working, it could be that the internal components are dirty. It’s common for dust, soot and dirt to build up on the mechanical and electrical parts, and this can affect the thermostat’s functioning. Once the components are clean, also check for loose wiring or connections that need tightening.
2. The room temperature and temperature setting doesn’t match. The dirty internal parts mentioned above can also cause inconsistencies between the temperature setting and the actual room temperature. Or, it could be possible that the thermostat was installed in a poor location, such as in direct sunlight or by a drafty window, making it unable to properly regulate the temperature.
3. The display on the thermostat is erratic. If the features on the display aren’t showing up or the screen is blank, it could simply be a case of old batteries. Try replacing them and see if that solves the problem. Another issue could be a tripped circuit breaker. If you’ve checked both of those and the display still isn’t working correctly, it could be time to request professional assistance with your thermostat.
4. The thermostat isn’t working at all. Again, before you start getting quotes for an entire new HVAC system because your thermostat appears to be totally dead, check the batteries and the fuse. The batteries could be expired, so make sure to replace them first and foremost. If the fuse appears blown, you can take it out and bring it with you to the hardware store to ensure you’re purchasing the right one.
5. Forgetting to set the thermostat for the season. If your furnace isn’t turning on on that first chilly fall evening, make sure you’ve remembered to adjust the setting based on the season! Here’s a tip: when you change the clocks, change the thermostat. Of course, here in Ohio we can never be too certain of the weather, so you may need to turn the heat on as early as September!
