WIP dryer repair part 2: swapping out the heating coil. - eviltoast

Well, the dryer has been disassembled and vacuumed, the dead coil removed, the new coil swapped in, ready to reassemble as soon as the new belt arrives. I was surprised how much of the brown shmutz in the heater was just ash from the coils - it dusted off quite shiny after I replaced the coil.

I’m a little worried about the visibly duller part of the heater assembly, hopefully that won’t absorb too much heat - I tried to cluster the coils a bit looser there to compensate.

It’s even visible on the reverse side.

Either way, I’m reassembling tomorrow when the new belt arrives.

    Thanks for reassuring about the dark patch. Yes, it’s the exact spot the coil burned. I assume there was a brief flame during the burnout.

    If you’re not in a big hurry, I would replace that white plastic bearing the drum rides on (you can see it on the very left in the last picture). It’s super squeaky when it fails. If you don’t replace it, at least give it a dollop of high temp grease.

    I picked up a (too big, too expensive) tub of high-temp lithium bearing grease for exactly that purpose. My only wonder is how thoroughly I should clean off the old grease before applying it.

      Getting all the old grease off isn’t super important. You mainly just want to get it clean enough to make sure the bearing surface on it and the ball on the back of the drum are smooth and not getting scratched/galled up.

        That’s what I’d assumed. Wipe it out with something lint free to make sure there’s no grit, then add the new grease.

          Some greases are incompatible, and not cleaning thoroughly causes them to react chemically and cause issue, but unless you’re in that situation, you don’t need to clean super well.
