Five common thermostat problems

Most thermostat problems are easy to fix.

  • You do not necessarily require an HVAC professional to repair these issues.

Familiarizing yourself with the most common thermostat problems can help you restore your faulty thermostat to proper working condition. These problems vary from mechanical to technical issues. For instance, your thermostat might fail to reach the set temperature. Ordinarily, thermostats are the control center of your heating and cooling system. When your room doesn’t feel any different after setting your preferred temperature, then there could be a problem. Typically, your room temperature should change when you change your thermostat setting. This problem could occur when your thermostat is exposed to direct sunlight due to its placement near windows or doors. This exposure will warm your thermostat and give it inaccurate readings, making the heater shut down before achieving the set temperature. Aging is also a common thermostat problem. Thermostats have an expected service duration before their effectiveness deteriorates. This may cause too many HVAC issues that prompt the need to replace it. Dirt in a thermostat is also a common problem. Inaccurate thermostat readings may sometimes result from dust build-up inside the box. The fourth thermostat problem is a miscalibrated thermostat. Thermostats come with internal sensors that the manufacturer calibrates to ensure proper readings. Over time, these calibrations become less efficient, resulting in uneven temperatures inside your home. Your compressor and fan may also turn on and off quickly, reducing your system’s lifespan. Then your thermostat display may stop working. The thermostat provides valuable information about your system’s current state through the display. If the display stops working, changing the temperature and checking the state of your HVAC system will be impossible.
