What Causes Your Furnace to Stop Blowing Hot Air?

   

A furnace is a heating system made up of many components and depends on all of them for its proper functioning. The entire heating unit will malfunction if there is an issue with any of the furnace parts.

A furnace that stops blowing hot air is also one of the outcomes of poorly maintained or damaged contributing components. If your furnace has also stopped blowing hot air, you should inspect it before scheduling a furnace service in Olney, MD, to find the primary cause.

Why does your furnace stop blowing hot air?

Once you find the main issue, you will know whether you should call a technician or fix it yourself. The top five reasons your furnace stopped blowing hot air are mentioned below:

  • A Malfunctioning Thermostat

Whether you use a programmable or non-programmable thermostat, both need your input to fulfill your requirements. The only difference is that a smart thermostat does not need instructions as often as a non-programmable thermostat.

The inaccurate instruction to the thermostat can cause hot air-related issues. In the summer, the temperature should be between 65 and 68 degrees in Olney. If the fan is set to “ON” instead of ‘AUTO,’ it will run continuously.

It should be turned off once the room temperature reaches the required level. Therefore, you should set the fan to automatic mode to prevent it from running continuously. Also, replace the battery when your thermostat is not working.

  • Unclean Furnace Unit

All the heating components should be clean because dirt can obstruct the furnace mechanism. A dirty pilot light will burn a flickering or weak flame. If the pilot flame weakens, the heat exchanger will not get heated.

It will slow down the entire heating process. As a result, your furnace will stop blowing hot air. If you schedule an annual tune-up service, you will not face cleaning-related issues with the furnace system.

  • Prolonged Dirty Filter

A dirty filter is the main reason behind the dirty furnace unit. If your furnace is costing you too much in electricity bills and not providing sufficient heating, the reason could be a dirty air filter.

You should replace the air filter within 30 to 90 days. A clogged filter can also lead to health issues and worsen allergies or asthma problems. If you have a washable air filter, clean it every two weeks.

  • Not Enough Fuel

Heating service experts in Olney, MD, suggest that if everything with your furnace system is fine but the furnace still stops blowing hot air, the reason could be insufficient fuel.

  • Damaged Heating Part

A crack, hole, or other damage in the furnace components will cause the furnace to malfunction. Suppose your furnace stops blowing hot air if there is a crack on the heat exchanger, a damaged blower fan, a grounded motor, or damaged insulation. You should immediately book a heating service in Olney, MD, to get your furnace repaired.
