Craftsman Opener Gear & Sprocket Replacement is one of the most common calls we get. A technician will explain what is wrong and what it will cost before starting, and test the door before leaving. Stripped drive gears replaced so the motor moves the door again. Our technicians service Craftsman garage door openers regularly and know where the model and date labels are, which makes ordering the right part quicker. Older Craftsman openers with model numbers starting with 139 were built by Chamberlain, so their remotes and parts often match Chamberlain and LiftMaster models from the same era.

Craftsman Opener Gear & Sprocket Replacement: frequently asked questions
How much does Craftsman opener gear & sprocket replacement cost in Kent, WA?

Can you do Craftsman opener gear & sprocket replacement the same day?
Often, yes. When a technician is available we can usually come the same day, and common parts are carried on the truck. Doors that won't close or have a broken spring are treated as priority calls, and emergency service is available.
Is Craftsman opener gear & sprocket replacement covered by a warranty?
Our work comes with a 90-day labor warranty on repairs. New parts and doors also carry the manufacturer's warranty, and Craftsman warranty terms vary by product and age. Ask for the warranty details in writing with your quote.
Are your technicians licensed and insured?
Our technicians are insured, and where Washington or Kent requires a contractor license for garage door work, the job is done under that license. You're welcome to ask for proof when you book.
Should I repair or replace my opener?
A good rule of thumb: if the repair costs more than about 50% of a replacement, or the opener is near the end of its life, replace it. Most openers last 10 to 15 years. If yours is older than that, lacks photo eyes or rolling-code security, or needs a logic board or motor, a new opener is often better value. Springs are the exception: a broken spring is always replaced, never repaired. Our free repair vs. replace calculator can help you compare.
