Troubleshooting Thermostat Problems Keeps Your Temperature Settings Running Smoothly

If your home’s heating or A/C system is malfunctioning, or just not working, you should determine whether your HVAC equipment or the thermostat is the problem. Usually, a thermostat problem is a less expensive fix than something in the cooling or heating system. Here is a list of some common thermostat problems.

HVAC System Won’t Run

Check to see whether your HVAC system and thermostat are getting power. The issue could be a tripped circuit breaker or blown fuse. Flip the circuit switch to the equipment off and then back on, and see if the system resumes operation. If the thermostat is powered by batteries, replace them to see if that works. Contact a trusted professional if these simple corrections don’t work.

Open the thermostat casing, and if it’s dirty take a small brush and clean it out. Over time, the thermostat’s workings will get coated in dust, which can interfere with its mechanical and electrical operations.

If the wiring is loose or even disconnected, try reconnecting it (but make sure the power is off before working with anything electrical). Call a licensed professional if you can’t correct the wiring problem.

Thermostat and Room Temperatures Don’t Match

This is another area where the thermostat might be dirty. If cleaning doesn’t work, check to ensure the thermostat is level. If it isn’t level, or has been incorrectly installed, it can offset settings and calibration.

Also, check that the thermostat is located in a good spot. It should not be placed in an area that receives direct sunlight or cool drafts. If it’s responding to atypical conditions, it won’t cool or heat other parts of the house properly.

Thermostat Shuts Down for No Reason, Or Won’t Shut Off

This is another situation where the thermostat might need to be cleaned. In a mechanical thermostat, there can be a malfunction in the anticipator, which could force an entire system shutdown for no apparent reason or keep it running even after the desired temperature has been reached.
