Potential garage door opener problems

[villagetinker]

I have helped a few neighbors with garage door problems, and decided to share the most recent problem that caused the neighbor to have to replace the opener. This was a loose set screw. Please see the PDF attachment for details.
Hope this helps. VT

what brand is this opener? i have found the mvp brand to buy parts on amazon , remotes are 6$ ,, locally. they sell for 46$ could you put lock tite. to prevent this vibrating loose again? i have had the capacitor blow a couple times because it was put up and down when a relay was chattering ,, easy fix if i have purchased parts from amazon the place on rolling acers road is outrageous on price!

DietPepsi, This was an MVP, sorry I should have included that in the info, also a fairly new unit, less then 4 years old.
As a follow up, I checked our units, and all set screws were tight. Yes, locktite will help keeping the set screws tight. Would NOT help with the lag bolts.
You are correct on the prices, the price for a replacement circuit board was over $123, my neighbor purchased a new garage door opener for under $140, and the 2 of us installed in a couple of hours.
