5 Common Thermostat Problems

Many homeowners have experienced the dread that comes from a broken thermostat. The sight of the device not working properly can cause stress and concern, especially during winter months. Loveland furnace repair services can be helpful in fixing a broken thermostat, but it’s also helpful to understand how the device works and how it can be restored. Here is a guide to troubleshooting your thermostat.

Problem: Thermostat Display Isn’t Working

Solution: If the thermostat’s display screen isn’t working, start by replacing the batteries behind the cover. Check the circuit panel for a tripped breaker, as well as the fuse behind the cover to make sure it hasn’t separated. Over time, a thermostat can wear out, especially if it is used frequently or in an area in direct sunlight, which can harm the screen. If these simple fixes don’t improve the display, it’s likely time to replace the thermostat.

Problem: Thermostat Doesn’t Control the Temperature

Solution: If changing the thermostat doesn’t do anything to change the temperature, there’s a chance your thermostat needs to be replaced. But before you run to the store, run through a few basic troubleshooting steps. Make sure that the thermostat is turned on and has new batteries. Start by turning off the heating system and removing the thermostat cover. Clean out any dirt, debris, or corrosion that naturally builds up over time and can get in the way of the thermostat functioning properly. Check that the thermostat is installed in a location where it has natural airflow instead of in the corner or near a door.

Problem: Thermostat Short-Cycles

Solution: If a thermostat short-cycles or quickly turns on and off again over and over, it is likely dirty. Remove the cover and gently clean out any dust with a soft brush or compressed air. If cleaning the device doesn’t work, short-cycling could be due to a loose connection. Check that the wires are tight and that nothing has come loose over time.

Problem: Thermostat Is on but Not Blowing Hot Air

Solution: Another common problem is having a thermostat that appears to be running, but the furnace isn’t blowing hot air. Start by checking the thermostat settings to make sure they are set to the right temperature. If something was nudged or changed, the furnace might simply be following the new settings. Replace the batteries in the thermostat and check that the system is clean. If that doesn’t work, the issue could be dirty furnace air filters. Air filters need to be changed about every month and can cause the system to stop blowing hot air if they are too dirty. Check that the furnace circuit breaker is working and hasn’t been tripped. If these simple DIY solutions don’t solve the problem, it could be a more advanced furnace issue.

Problem: Thermostat Temperature Doesn’t Match the Actual Temperature

Solution: Your thermostat could say the room is 70 degrees, but a separate thermometer may say the room is actually 75 degrees. If your thermostat has inaccurate temperatures, check to make sure it is properly installed in a central area away from doors and windows. A thermostat in direct sunlight or near a corner won’t get an accurate read of the room’s temperature. It could also be that the thermostat is old and needs to be replaced to get more accurate readings.
