Reasons Your Heater Is Not Working Even If The Thermostat Is On

Nov 8

Does the temperature indoors feel different than what's on your thermostat? Have you cranked up the heat, but your home still feels chilly? Well, there are a few reasons your heater might not work even if the thermostat is on.

Why Is Your Heating Not Working Even With The Thermostat On?


It's definitely frustrating to have your heater not working when you need it the most. But before you call for a heating repair in Irving, TX, you can check a few things on your own.


Dirty Filter

When the filter is full of dirt and debris, air won't flow as freely through the system. This puts stress on your heater and can cause it to work less efficiently or not at all. Depending on the type of filter you have, you'll need to replace or clean it every few months.


Closed Gas Supply Valve

Gas-powered heating systems feature a supply valve that allows gas to flow into the unit. If this valve is closed, gas won't be able to reach the unit, and it won't be able to produce heat. It is a good idea to check this valve before you call for heating repair in Irving, TX.


Faulty Ignition System

If you have an older furnace with a standing pilot light, a problem with the ignition system can prevent it from lighting. If you have a more modern furnace, a faulty ignition system can keep the burner from igniting. In either case, this will prevent heat from being produced.


Improper thermostat calibration

If your thermostat is not calibrated correctly, it might be reading the wrong temperature. As a result, it might turn the heat on when the temperature is already at or above the set point. Conversely, it might not turn the heat on until the temperature has dropped significantly below the set point. Thermostat calibration is relatively simple, but heating repair techs in Irving, TX can also do it for you.


When to Call a Professional for Help


A malfunctioning heating system in the winter brings more than just discomfort - it can be a safety hazard. There are instances when a problem with the heating system brings imminent danger and calls for an immediate response from an expert in heating repair in Irving, TX.


A heating unit that's not working may pose a risk, depending on when the heat went out and the severity of the weather. If it's during a cold snap and you have elderly family members or small children in the home, call a professional right away. In some cases, you might be able to troubleshoot the problem and get the heat working again until a professional can come out. But if you're uncomfortable doing that or the problem persists, don't hesitate to call for help.
