For all you do-it-yourselfers or pioneers or el cheapos, here is a safety tip. For the rest of you, just hire or nag someone else to check on this. Tuesday I was just trying to get some housework done when something fell in the lint catcher in my dryer. I heard the metal sound, thought uh, oh, and decided to investigate. I tried a magnet to fetch it out, but as the innards of the vent are all metal, it only went so far. Next, I thought a magnet in a bag that I threw down quickly might do the trick. No dice. It still stuck. Then I tried a long strip off the front of my husband's desk might do something. As I stuck it down ever further into the depths of the dryer, I noticed something soft. Oh...lint? down there? Not good. Out to my husband's shed I went, hunting an adjustable wrench, some normal wrenches, and back to my very own tool drawer to get my very own ratchet set. (Warning: I only scored 8 on the military's mechanical aptitude test when I was in high school. I am sure that I would now score 9 because I know that a monkey wrench is really an adjustable wrench..I think). The wrenches were not the right size but the ratchet set worked. I even remembered that sometimes you push the little lever on the head one way to take the screws off and another way to tighten. That's handy. I got them all off, the back removed, the back of the vent off and there it was! Packed lint that had accumulated for years, with a nail in the midst of it! Oy! Danger Will Robinson! I had faithfully cleaned the lint catcher for years (yes, it is an old dryer), vacuumed periodically, and yet all along this insidious dust had built up to a sizeable amount. I cleaned and dusted and vacuumed, stuck a duster in another spot that goes in around the drum and pulled out some spider webs. So much safer now! I had no idea what a hazard was building up in my own laundry. I was able to put everything back together and it still works! Hallelujah! ...I did find two more screws, but who's noticing? Shalom and be safe. P.S.: put the lint catcher back in place while working because it attracts metal objects including adjustable wrenches that also fall down the lint shaft.
