Liftmaster rack keeps stripping

I have a Liftmaster and the rack keeps stripping out. We have had new springs and ballbearing rollers put in, but it still keeps stripping. We have to put in a new rack about every 7 to 8 weeks. Why does it keep doing this? It is a 1/2 hp on a 18ft garage door. It worked fine the first 8 years after building the house. Then all of a sudden it starts the stripping thing.

What do you mean by rack. do you mean fears. do you have right sprigs on door, is door balanced. lift half way and let go (Disconnected by arm). It should stay put or go slowly up or down. If not, springs are bad, I put a 1/4 hp on 18' wood door. lasted 27 years so far. H/p not the problem.

Liftmaster GDO goes up 1/2 way and stops,springs are fine.


The Liftmaster openers have 4 movement switches, a )opening and b) closing limit and c) opening and d) closing force. First check the door for smooth operation by opening the door by hand (disconnect from the opener with the release cord). Any binding should be felt this way. It is possible for a binding hinge, roller or torsion springs to add too much drag and cause the force switch to shut off the motor. Hinges, roller shafts and torsion springs should be lubricated at least annually with a non oily spray (silicone or teflon spray). Not WD-40 or 3-in-1! A light band of lube should be applied to the torsion spring coils. If the door can be operated smoothly by hand, then adjust the closing force switch 1/4 turn at a time. This is a safety device do not use it to overcome another problem!

Top roller screw hole stripped


1)make certain all is clean and very dry
2)apply gorilla glue into stripped plastic hole and insert screw.
3)rig something up to keep it from moving for 6 hours or so

careful gorilla has a nasty habbit of pretty much destroying clothes and staining skin so be carefull. don't get carried away when applying it and maybe set down a disposable rag to catch drips.
but it is very permanent. Its what I would do

good luck

Liftmaster garage rack won't return/open. It gets stuck about 1ft from the closed position. I thought the rack was stripped but it seems fine. The motor is really loud. When I press the button again the...


It sounds like something needs lubrication badly or the track is not aligned properly with the door and it is binding. It is also possible the limit settings are way off. Sorry I cannot offer more help.

Top rack rail contently comming off the rollers. The rollers are wobbly, tried to tighten but will not go any tighter. are there better rollers available? PLD2850RDC2


Typically the roller wheels and the post tabs that hold them onto the sliding rack/guides will wear over time and depending on how heavily your family loads the racks, the sooner you'll need to replace them.

You can order new ones and do the job yourself which is the best solution for the situation you're describing. The only other thing to check is for the rack section that is attached to the inside dishwasher walls to make sure those screws are snug (don't overtighten and strip them out!) other than that, you still will need to replace the rollers on the extendable portion of the rack supports, etc. Hope that helps.

How do you replace rack on liftmaster? Mine is stripped


why stripped again in only one year. is door balanced. lift half way and let go (Opener disconnected) and does door stay there? If it slams down, check springs.

hi Problems with the dish racks usually occur because the racks have been jammed back into the tub housing after they're fully loaded. Careless handling can exert enough force to crack or break the roller wheels or throw the racks off the tracks. The solution is easy: Stop jamming the racks. 
The repair is easy, too. Remove the racks by pulling out the tiny metal pins that hold them in the tracks. Or simply lift up on the racks and pull them out of the tracks. Then reinstall the racks on the tracks so that they roll smoothly. If the rollers are cracked or broken, replace them with new ones of the same type. The rollers may be friction-fit to their hubs. Pull them off for replacement. Or, if they are held by tiny spring clips, pull the clips out with pliers, or pry them out with the tip of a screwdriver. If you can't pull the rollers off for replacement, remove and replace the entire rack.

The bottom rack of the dishwasher is always coming off the "track" or what passes for one. The wheels seem too small or the rack isn't wide enough Makes it very diificult to push in or pull out.

A noisy wash cycle or water that won't drain are problems that, for the most part, can be handled yourself. We'll discuss how you can pinpoint these water-related problems in the next section.

Top rack keeps slipping off of tub rollers.


I was sold this model and had the same thing happen.. However when calling for service, my service rep would not come out, so I contacted Fridgidaire and provided the model and serial # of my unit and was told I was sold an unrepairable unit that had already been returned for service for the same thing and considered unrepairable and was no longer under warranty. When my supplier finally came out he put new longer rollers in my dishwasher, but when I mentioned what Fridgidaire had told me, he went back to his supplier and they got me a new one. Being installed today.. The new one is a PDA2855 model as I am told that the PLD2850 is no longer sold.
