Warning: stop using WD-40 on dryer drum rollers

Ngl I've pulled apart at least 30 dryers this year where someone sprayed WD-40 on the drum rollers thinking it would fix a squeak. Problem is that stuff doesn't have any real lubricant properties for nylon parts and actually attracts lint like crazy. Had a call last week in Portland where the rollers were so gummed up the belt had basically welded itself to the drum. You're better off spending the $8 on proper lithium grease at Home Depot. Anyone else see this mistake all the time?

That freezer evap fan that sounded fine but was pulling 2.5 amps nearly burned my hand off

Pulled a fan motor on a walk-in cooler last week that hummed quiet as a whisper but was drawing 2.5 amps instead of the rated 0.8, melted the winding insulation inside so bad the housing was too hot to touch. Has anyone else gotten bit by a fan motor that seemed fine on the bench but was secretly cooking itself?
