I've had the same washer and dryer for about 15 years. They were mine before I even knew my wife. She has wanted to buy a new set for the last 10 years that probably costs $5k or more, no idea what they run these days. But I've been in the camp of if they're not broken and work fine, why spend the money. I've held out for years.
She called me in this morning to the laundry room(with a smile on her face as if this was her shot at a new set) and she said the dryer was on fire. Wasn't technically but there was an odor of something burning. I pulled the lint trap it was clear, blower exhaust housing/tube was clear. But the back of the dryer was too hot to touch. Definitely overheating.
After some www'ing, I'm prepared to purchase and replace a new control thermostat, new gasket/seal set for blower housing, front door, and lint trap, as well as new door latch & catch.
It will be good as new, and a small but satisfying victory!
