We hope you know you are supposed to clear your lint filter every time you run a dry cycle.
Did you ever consider the lint that is actually inside your machine? Over the years lint seeps into the mechanism of your machine, potentially causing a fire hazard. If you don’t make a habit every few years of maintenance on the inside, this can be a potential source of fire. Immediately upon smelling burning, stop using your machine. Call an authorized repair representative and have them disassemble your machine completely and look inside. The representative should then thoroughly clean out all the lint that remains in your machine. This is one important step no one cautions you about, but if followed can help prevent fires. Look at the pictures here and see an actual client of AJR, and the lint contained on their machine.
Next time you smell something funny, do not ignore, get it checked. Dryer fires are a serious event, its best to do all you can to prevent a fire in your property.
