Make sure all the lint is cleaned out of your dryer. We stored ours once for a short time & when we used it again, it was a miracle we didn't burn up the house. It was fire red back there. Home Depot/Lowe's sells some of those tools that reach down deep into the dryer. Also take the hose off the back and clean up in there. That's about the only advise I have for you.
