Why is My Digital Thermostat Not Working?


You rely on your digital thermostat to communicate with your HVAC system and tell it how much cooler or warmer it should make your home. However, if your thermostat is malfunctioning, you may find that your home is much hotter or colder than you’d like it to be.

Whenever you notice signs that your digital thermostat isn’t working properly, it’s important to have the system inspected by a professional. From there, they can recommend either repairs or a unit replacement to keep your home nice and comfortable.

Common Causes of Digital Thermostat Issues

Wiring Issues

Wiring issues with your home’s digital thermostat can cause the screen to go blank or even completely cut off power, among other things. If you believe that wiring problems are contributing to your digital thermostat issues, get in touch with a heating, cooling and indoor air quality professional. Many times, wiring issues can be repaired and won’t require a complete thermostat replacement.

Poor Positioning

Your digital thermostat’s placement is much more important than you may think. For example, a thermostat that was installed near a window will likely read higher temperatures as direct sunlight hits the unit. Your thermostat will think the temperature is higher than it actually is, causing your heating and air conditioning system to turn on and off before your set temperature is actually reached. Meanwhile, installing a thermostat too close to heat-producing appliances can also cause it to read a higher temperature. If your thermostat was installed in a poor position, get in touch with a professional to discuss having the thermostat moved to a better location within your home.

The Unit is 10-15 Years Old

Just like the rest of the HVAC and indoor air quality equipment within your home, thermostats become less accurate and reliable as they age. Generally speaking, if your thermostat is within 10-15 years of age, it might be time to have the system replaced. However, with proper cleaning and maintenance, you’ll likely be able to keep your thermostat operating at its peak for longer.

Thermostat Needs to Be Cleaned

Despite your best efforts to keep your home free of any dust or gunk, thermostat issues can commonly be caused by dust and dirt buildup. Cleaning the system thoroughly will remove any buildup and will help the system read temperatures more accurately and effectively.
