Troubleshooting Thermostat Problems Keeps Temperature Settings in Check


If your home’s central A/C or heating system malfunctions, or doesn’t work at all, you should try to determine whether your HVAC equipment or the thermostat is the problem. Generally, it’s better if it’s a thermostat problem since that’s usually a cheaper fix than something in the cooling or heating system. See a list of common thermostat problems.

HVAC System Won’t Run

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

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

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

Thermostat and Room Temperatures Don’t Match

This is an additional situation where the thermostat might be dirty. If cleaning does not work, check to ensure that the thermostat is level. If it’s not, or has been otherwise incorrectly installed, it might offset settings and calibration.

Also, make sure the thermostat is placed in a good spot. It should not be installed on a wall that receives direct sunlight or cool drafts. If it is responding to atypical conditions, it will not properly cool or heat other parts of the house.

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

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