Lennox ComfortSense 3000 Thermostat

Posted: 2018-10-16

Your HVAC system’s thermostat, though a tiny device, plays a significant part in creating a comfortable indoor environment. If it’s not working properly, it can affect your overall comfort. Common thermostat problems can also reflect more serious issues with the AC system or furnace, and if neglected, can cause unnecessary burden and discomfort.

Four Seasons Air Specialists is a licensed HVAC company in Lino Lakes MN that offers a wide variety of thermostats ranging from programmable to state-of-the-art connected or smart thermostats.

Most Common Thermostat Problems

No Power

If you’re trying to make adjustments on your indoor temperature and your thermostat is not responding at all, there could be a number of reasons for this malfunction. Even if you clean your home regularly, dust and dirt can accumulate and settle inside your thermostat. If neglected, this can affect the overall performance of the thermostat, causing you a lot of trouble and inconvenience.

Also, loose wires can cause the thermostat to stop working. You need to ensure that there is no wonky wiring in the thermostat, and if there is, call your local HVAC professional.

Just like any other electronic device that runs on batteries, there will come a time when the charge on the batteries will run out, leading to the thermostat not working.

Failure to Reach the Desired Temperature

If your system turns itself on and off a lot and it is not reaching the temperature you have set it at, this could mean that there is an internal problem with the device. Moreover, if you notice some inconsistencies in your home’s temperature without making adjustments on the thermostat, your thermostat may need to be repaired, or worse, replaced.

Being Too Close to Heat Sources

When your thermostat is placed near sources of heat like a stove or direct sunlight, it is highly likely that it will display false temperature readings. To avoid this problem, make sure that the thermostat is at least a few feet away from heat sources.


Old or Faulty Thermostat

While thermostat can last for years depending on usage, but occasionally they do stop working and would need to be replaced. If you’re using a thermostat that is still equipped with mercury, you may want to consider upgrading to a more accurate, energy-efficient model. According to the Department of Energy, by using a programmable thermostat, you could save as much as $180 per year.
