Whenever I do appliance repair I load it up and take it back to the shop so I can work un aided…. I can fix most “funny noises” by procrastinating. WD40 does the rest.
Every now and then I’ll hit a snag. Garage door opener was acting up. I worked on it, banged on the side of it, reset it, sprayed WD40 all over it and the door and the tracks… then one day it started working correctly again… I took credit for fixing it...
