Has Your Heater Stopped Working Altogether? | Airco Service

Posted on: Dec 20, 2018

As part of your preparations for the cold season, it’s likely that you’ve prepped your heater to generate and efficiently circulate warm air throughout your home 24/7. Unfortunately, things won’t always go as planned. Despite your spirited efforts to prepare your heating system for a grueling winter, the system could still fail.

Of course, there are different ways the heater could fail. However, if the problem is failure to turn on when you switch it on, we know exactly what you need to do. Here are the top three reasons your heating system might refuse to turn on and how to address the problem:

  • Thermostat Issues

Perhaps the thermostat power isn’t turned on or the circuit board isn’t getting power. It is also possible that the furnace door isn’t shut properly. Most heaters have a switch inside the door that cuts off power to the main unit if the door isn’t properly closed. Another thing you may want to check is the batteries and fuse. If yours is a battery-operated thermostat or if it has a fuse, check to ensure that the batteries are working and the fuse isn’t burnt out.

  • Filter Issues

This might come as a surprise to some people, but yes, a faulty or nonfunctional filter can cause the home heating system to stop working. A dirty filter, for example, can keep your unit from heating properly. Warm air that goes through the filter is limited since the unit is simply blocked. You can remove the filter on your own, check to see if it’s dirty, and replace it as needed. More importantly, stick to the rule of replacing your filters every two to three months.

  • Ductwork Issues

Finally, it’s also possible that your heating woes are the result of malfunctioning or grossly inefficient ductwork. Your home’s ductwork system must be properly installed. Otherwise, you’re guaranteed to run into efficiency issues. Also, it’s important to inspect your ducts before the cold season sets in to ensure that the dampers are properly adjusted. Properly adjusted dampers allow the free flow of air around the home.
