Hello All!
We bought our 16' Wayne Dalton "Thermoguard" garage door about 4 years ago and have been very happy with its performance so far. It has a "Liftmaster" 1/2 horsepower opener.
About a month ago it began to make a lot of racket when it was closing [from the fully opened position]. When it opens, it's quite; it's just when we close the door that it seems to make noise. The wheels shake [slide left and right in their metal guide tracks] a little but are not broken; it's like the wheels are banging on the side rails somewhere, I just can't see it, maybe! The opener has a "screw-type" rod which works fine, so it is not the problem either.
No amount of lithium grease/WD-40/silicone spray is going to remedy this.
I've called the installer; they want $150 for a house call to do the adjustment.
We're seniors and have some discretionary funds, but if I can make the adjustment[s] myself, [with your help!] I'd rather do it. Can you help us?
Many thanks for taking the time to respond! :-)
