Top 4 Tips for Troubleshooting Your Faulty Furnace

Top 4 Tips for Troubleshooting Your Faulty Furnace
  • Opening Intro -

    It's frustrating to wake up on a chilly morning and turn on your heat, only to find there's no heat coming out of the vents.

-------------------------------------

There could be a number of things that lead up to this problem, including something quite simple to fix, a complex mechanical repair, or a necessary equipment replacement. In order to determine what’s going on with your furnace and why it’s not working properly, follow these four troubleshooting guidelines to possibly resolve the problem on your own or find out if you need to call a furnace repair specialist.

1. Thermostat

Check your thermostat setting. Is the fan turned to the “on” position? It must be on for it to properly operate. Therefore, adjust your setting to either “fan” or “auto”. If you choose “on”, the fan will keep running even after the heat turns off. Adjust the setting to “auto” to shut the fan off when the heat stops running. Also, make sure the thermostat is set at least 4 or 5 degrees over the current room temperature; if it’s not, the furnace won’t kick on right away.

2. Power

Is your furnace getting power? Check the fuse box or service panel for your home in the basement or garage. In most homes, the furnace is wired directly to its own circuit. During a power outage due to a storm, the home’s electrical system can make the circuit breaker of the unit trip or a fuse blow. Before trying anything else, first determine if a lack of power is the culprit behind your furnace problems.

3. Blower Motor

The last troubleshooting tip is to check that the furnace door is completely closed, since an open door will make the furnace work improperly. If the door is properly closed, a switch just inside the door will engage. Next, go to the circuit breaker and turn off the power to the furnace. Find the blower motor and check the belt for any visible cracks. Is the belt frayed or broken? If so, replace it to fully restore the function of the blower motor. However, in order to completely repair a faulty blower motor, contact a heating, ventilation, and air conditioning expert from HVAC servicers.

4. Vents and Filters

Before you start progressing to more complex furnace problems, simply check all the vents in your home to make sure they’re open. Find your home’s cold air return and remove the filter to take a look inside. A clogged or dirty filter, or one that’s installed incorrectly, can negatively impact the air coming through the ducts.

By performing regular furnace maintenance, it will keep your unit in good working order and extend the overall life of your unit as well.
