5 of 5 Life Savers....... April 2, 2023
Reviewer: James C from Knoxville, TN United States  
My Craftsman Garage Door Opener broke after  six years of operation. The gear driving the chain  came off the shaft. I panicked after searching the "Sears" Parts Online. Sears showed the part for my Model HOWEVER they said the part was no longer Manufactured.!! I thought "Oh Sh*t, now what do I do.?"

BUT, after searching for the Model # I stumbled onto STAR Doors. I emailed them, asking if they had my part,  and they came right back to me. Assuring me the part I asked about works with my Model # Opener.

They delivered the Part quickly and allowed me to get back in business in no time at all. I have their name and number filed away for the next emergency. Definitely count on them to support your needs.!!

5 of 5 Great solution! January 31, 2023
Reviewer: Brett Niver from Whitinsville, MA United States  
Hard to find parts with step by step instructions.  Got my garage door opener fixed and running again.  The kit where you just replace the entire vertical gear assembly is probably the easiest to use.

5 of 5 Great product, great service. June 11, 2020
Reviewer: Doug from Dublin, CA United States  
The   LiftMaster® 41C4220A Gear & Sprocket Assembly was exactly what I needed to get my very old Sears 139.53603 opener working again.
I emailed Star Door Parts about my specific model # (which is not listed on the website) and received a prompt, courteous reply that this was the kit I should use.  It arrived sooner than expected, the repair instructions were good and everything fit perfectly. At first I was worried that the tube of white grease was a little small but it turned out to be more than enough for all the internal gears.
I have no regrets at all about purchasing this kit from Star Door Parts.
