Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
Daughter came home from work and the door struggled to get open and then it wouldn't do anything when she pressed the button to close. We checked the sensors and they are fine. Landlord said since it broke when we were using it I have to fix it. I disagree but once again I'm the one that needs it working and it took him 2 months to fix the leak in the kitchen. I need a quick and easy fix for this problem that isn't expensive. Garage places said it would be $130.00 for them to come out and fix it. They think the gears went out. I am divorced and EX kept the tools so any assistance I can get is appreciated.
I had a similar problem with a Craftsman opener. There are 2 gears that are in the housing, these are made of nylon/plastic and are built to wear out over time. My model was 139.53664SRT , the gear kit is 41A2817 and you can order the entire thing from Sears.com. If you get the housing off you can see if you just need one of the gears, either the drive gear or worm gear , you can order those off of ebay pretty cheaply. You'll need screwdrivers and probably some wrenches to get things apart and install the new gears, you'll also need to use lithium grease on the gears, that keeps the gears from eating each other up too quickly.
