DAE vacuum out the vent line every time you replace a dryer thermal fuse?
I learned this after a few annoying callbacks. Dryers that keep blowing thermal fuses often have blocked vents, not just a bad part. Last week, I found one where the lint was packed solid behind the dryer. Idk, maybe it's just me, but I make it a point to vacuum out the vent line every time now. It adds like five minutes to the job and stops the same issue from happening again. I've told a couple other repair folks, and they said it saved them headaches too. Just a friendly warning to always look past the obvious fix.
My buddy had a customer with a dryer that kept shutting off. He replaced the fuse three times in a month before he finally checked the vent. The pipe behind the wall was packed tight with lint, like a solid tube. He told me he felt pretty silly, like @adam_robinson said, for not vacuuming it out the first time. Now he checks every single job and hasn't had a callback since.
