Can a Dirty Filter Stop a Furnace from Working?

Dirty air filters can be the cause of an oven that works inefficiently. These filters trap dust, dirt, and debris, such as hair, which can restrict or block vital air flow, overheating the heat exchanger and preventing the oven from working properly. A clogged oven air filter will also affect the airflow throughout the house and the HVAC system. The lack of fresh air in the oven will cause the heat exchanger to become too hot and deactivated.

Dirty filters can lead to short cycling problems and make it difficult to maintain heat in your home. It is recommended to replace the clogged air filter before the summer season to avoid damaging the air conditioner compressor. The fan performance of the heating and cooling system has a major impact on your home's energy consumption. The harder this fan has to work to attract air to the entire house, the higher your energy bills will be.

In fact, a clogged filter can consume 15% more energy, according to the Department of Energy. This inefficiency increases rapidly as the filter becomes increasingly clogged or until it is repaired. If this happens too often, the electronic protection of the “limit switch” may fail and then the oven will not turn on at all. Changing your oven filter is a simple way to prevent problems from occurring and maintain the health of your oven.

The heat generated inside the oven could cause extensive internal damage, which is the main cause of equipment failure. Running an oven without a filter overnight, for example, isn't likely to cause problems, but it should never be a long-term solution. If you have pets or have a lot of chemicals in your house, indoor air quality will worsen even more if the filter is clogged. The internal oven fan is designed to expel air through the HVAC air filter to provide air to the entire house.

Even if you decide to wait for maintenance during the winter, adjusting the oven is still important and useful. However, regardless of your appearance, you should change your filter after three months for 1″ filters and every 6 months for 5″ filters. If your home uses another type of heating system, such as a boiler that uses water to heat the house, it won't have filters, but for a furnace or heat pump, a filter is a vital component. When an air filter is clogged, the air controller must do more to compensate for the airflow blockage.It may not be obvious at first, but with clogged air filters, air flow is hampered and restricted.

To find out when to change the filter, consider installing a CleanAlert FILTERSCAN WiFi air filter monitor. If the oven cannot be turned on, this is an indicator of damage to the fan, pilot light, heat exchanger, pressure switches, gas valves, or other components. If the filter becomes too clogged with dust, dander, and dirt, the fan will have to work harder to get air through a clogged filter.
