Dirty air filters can be the cause of an oven that works inefficiently. This is because air filters trap dust, dirt, and debris such as hair, which over time can restrict or block vital airflow, overheating the heat exchanger and preventing the oven from working as it should. The most important damage that a clogged air filter can do to your home is the damage it causes to your oven. A dirty filter can prevent the oven from heating up your home. As with your HVAC unit in summer, an oven that can't dissipate heat efficiently heats up more and more.
Ovens have what is known as a limit switch, which will automatically turn off the oven when it reaches a specific temperature. When an oven filter is dirty, it prevents the air filter from picking up airborne debris instead of letting it pass to the rest of the oven. If you suspect that your oven is not working properly because you haven't changed the air filter, first check the kill switch and circuit breakers to make sure the oven is actually turned on. Often, when the oven filter is too clogged by dirt or debris, the electronic protection of the “limit switch” can also end up failing or failing. But sometimes, problems with your oven due to a dirty air filter will prevent it from generating enough heat when you need it most.
To avoid poor air quality and increased energy costs, follow the manufacturer's guidelines and replace your oven filter regularly. In addition to dirty burners, many of the other items on this list can cause your oven to start using much more fuel than normal. The repair can end up easily emptying your pockets, so make sure you replace the oven filter in time. If you don't feel comfortable or don't have the time to do so, be sure to schedule regular maintenance for your heating and air conditioning system, including filter replacements by a certified HVAC technician. Just like changing engine oil and air filters in your car every 3,000 miles to protect its mechanical parts, a clean filter protects your HVAC system from damage and ultimately from failure altogether. You can spot some signs that it's time to replace the filter even before the oven shuts down completely.
In fact, one of the main reasons we visit homes to repair the oven and air conditioning is because a system has been working with a clogged filter. Replace the HVAC unit air filter at least once every six months, or according to the manufacturer's guidelines. When the air cleaner is dirty and clogged, the oven must work harder than usual to compensate for the increased airflow blockage. A professional HVAC technician can resolve these issues for you and let you know how often to change your oven filter to avoid these problems. Regular maintenance of your furnace will help ensure that it runs efficiently and safely for years to come.
