Without a new air filter, the oven will overheat every time it is turned on again. This is known as short cycling. Dirty oven filters cause the oven to work harder than due to decreased airflow. The harder your oven works, the faster your parts will wear out and need repairs.
If the air cleaner is not serviced often enough, it will eventually become clogged to the point where air cannot pass through it. When the oven is operating, the lack of air flow will trap heat in the system. As the temperature inside the system continues to rise, the limit switch will turn the oven on and off to prevent it from overheating. This will temporarily mitigate the problem, but will not resolve the root of the problem.
The danger of not changing the air filter in the house for a long time is that it will eventually lead to damage to the oven. This means that the entire system will be destroyed by excess heat. Getting the most value out of your home can be as easy as changing air filters. Homeowners who ignore filters in their heating and air conditioning systems risk increasing energy costs, damaging expensive equipment, and decreasing indoor air quality and personal health.
See below to learn what can happen if you don't change your air filters. Replacing the air filter and having the HVAC system inspected regularly are part of a preventive maintenance routine. Failure to change the air filter can damage other parts of the system and can result in a large repair bill later on. Changing air filters regularly can help preserve the life of your system and make it work more efficiently.
In the long run, this will shorten the life of your HVAC unit. The filter is installed in the return duct, so that all the air that flows into the oven must first flow through the filter. These filters prevent particles, dust, allergens and other elements from entering the oven and damaging it, and then circulating in the air in the house. You may wonder how important the air filter can really be, if you've gone so long without changing it and the system apparently works well.
Of course, the goal of this post is to make it clear that you would save yourself a little frustration if you changed your air filter every few months. Air passing through a dirty filter can increase, rather than reduce, these allergens and cause adverse reactions for anyone living in your home. Keeping your oven filter clean can change oven efficiency and even lower utility bills. However, some older models have air filters inside them and you may need to have the right tools to replace the filters.
Dirty filters not only obstruct the amount of air that can flow into the oven, but also allow particles, allergens, dust and other elements to be released into the oven and then circulate with the hot air. Keep in mind that buying air filters online is not only convenient, but bulk purchase discounts and auto-renew options can save you time and money. Remember, replacing air filters costs less than $50, so don't let delay and negligence cost you thousands of dollars.
