It’s frustrating to turn on your furnace and discover that it’s not functioning as it should.

To give you a better understanding, this furnace repair company in Woodridge, Illinois is going to explain some of the most common reasons why a furnace might be running but not blowing warm air.

What are the reasons your furnace isn’t blowing air?

Furnace repair company in Woodridge IllinoisIn many cases, the reason your furnace is running but not emitting warm air is due to problems with certain parts like the motor or blower module. The blower’s purpose is to push the cold air out and pull warm air in to allow the air to circulate. But once the blower fails, air cannot spread indoors.

If you discover that the blower is not the culprit, it could also be from several other things, such as a damaged control board. Whether the damage results from age, power surges, or the capacitor, a damaged control board will need an expert to diagnose, repair, and replace the system.

Another possibility your furnace may be functioning but not emitting air in your Woodridge, Illinois home is a dirty filter. If the filter has dirt clogging it, it can block the airflow.

Can this problem cause the furnace to break down?

Depending on why the air isn’t coming through the vent, you may experience a furnace breakdown, especially if it causes the heat exchanger to get extremely hot.

The limit switch sensor is near the heat exchanger, and once it senses the furnace is too hot, it auto shuts down. The job of the control board is to turn on the blower to cool the system. If the control board or blower is not functioning as it should, the overheated system will fail to turn on. If your furnace overheats, it’s recommended that you contact your local furnace repair company in Woodridge, Illinois and have the system inspected.

What parts of your furnace should you check?

Ensure that your thermostat is at a specific temperature and that no one turns it off. It must be set correctly. But if it is not, it is recommended to set it for 5°F higher than the temperature in your home and check if the heater fan turns on.

  • Examine the circuit breakers. If you have done electrical work recently or installed a new water heater in your Woodridge, Illinois home, it could be that your furnace breaker was accidentally turned off. It is recommended to check your main power panel and examine the circuit breaker.
  • Check the air filter. Examine your heater’s air filter because it can cause the furnace to stop blowing air. Your filter may have too much dust. In this case, even though the furnace is functioning and blowing air, your clogged filters are preventing them from flowing into your ducts. With that said, it’s important that you change your air filter every two months or so.
  • Check the blower fan. After ruling out possible problems mentioned above, the cause of a furnace not blowing air could be the blower fan. Another problem could be the furnace fan limit control switch which needs pro-level troubleshooting. This is an issue that is best left to a licensed furnace repair technician in Woodridge, Illinois.
