Why Does My Microwave Vent Fan Keep Running?

Have you ever been doing something around the home only to be started by a loud and annoying microwave vent fan that just won’t stop running?

This can be a common problem for many people, and it’s usually caused by a few different things. In this blog post, we will take a look at some of the most common reasons why your microwave vent fan might be running constantly, and how you can fix them.

If it is, you can clean it or replace it to get it working again.
