What makes you think motherboard?Mother board. I replaced the mother board on my LG dryer a couple of years ago. I think it was about $400.
I had a pulley that was shredding my belts. Got new belts too many times, even a new pulley which didn't help.BELT - easy fix, done it a few times. In my case, the pulley falls off the threads if there is a sudden stoppage or power failure... Last fix I put a dab of lock-tight on the pulley threads... no more falling off of the belt/pulley.
Yup, it's usually the belt though. It's easy to fix if you have both the basic tools and the slightest mechanical ability. Otherwise, the appliance repair persons will be paying a large portion of their kids college tuition.Bad motor or broken belt is my guess.
Just curious, but why did you need to buy a new drum if the it was just the belt that broke?Our son overloaded the dryer with very wet clothes and broke it. DH bought a new drum under $150, followed YT to replace it and it’s been fine a few years since. Well, except for buying a new lint filter twice because the kids managed to crack them twice. Smh. At least they’re doing their own laundry right?
