Thermostat Diagnostics: 5 Tips to Follow

A thermostat may be small in size, but it’s huge in importance. This device is in control of your entire HVAC system; it dictates when and how heating and cooling units operate. Below are some of the steps you can take if your thermostat begins to malfunction.

Take the Temperature to the Extreme

When it comes to thermostat diagnostics, one test that you can perform is to set the device’s temperature several degrees above or below its normal setting. Set it 5°F higher in the winter and 5°F lower in the summer months. If the device doesn’t respond accordingly, there may be a problem with it.

Check the Other Settings

Your thermostat can’t talk to the right equipment if it’s in the wrong mode. If you want your cooling unit to operate correctly, your thermostat should be set to “Cool”. But if you want your heating unit to function, your thermostat should be set to “Heat”. 

Look for Dirt Build-Up

Dirty thermostat components can cause your heating and cooling system to underperform. Dirt build-up is also a cause of short-cycling, a phenomenon where the equipment turns on and off too frequently.

Find the Source of Sunlight

The thermostat may think the air temperature is hotter than it actually is if it’s being hit by direct sunlight. You may also observe the same problem if your device is located too near a window or exterior door. 

Consider the Age of Your Thermostat

Old thermostats ultimately fail. If you believe age is a major factor in the problems it’s having, consider replacing your device.
