When I shop at Costco, I expect to receive a quality product at a competitive price. Usually, I am extremely happy with my purchases, but that garage door I purchased from them has turned out to be quite a doozy. Mind you, the garage door itself is fine. The problem is with everything else attached to that garage door.
So, three years in, one of the torsion springs broke. Only three years? So, I found another contractor to replace both of the torsion springs and I didn’t think much about the garage again until a few months ago when the garage door opener started failing intermittently. Sometimes the door would not open all the way. Other times it would not close all the way. I had not problem with the opening, because I could always click on the garage door opener a second time. However, the closing was a serious issue because unless you monitored the garage door every time to make sure that it closed completely, there was always a chance that the garage door was not securely shut.
Long story short, I replaced the Chamberlain Whisper Drive 1/2 HP Belt Drive garage door opener, which was not all that quiet, with a LiftMaster 3850 DC Motor Belt with EverCharge Standby Power System. After I changed the garage door opener, the problem completely disappeared and the new opener is amazingly quiet. No more rattle and shake when the door is opening or closing. Just solid and quiet.
