Our opener gear & sprocket replacement service in Erwin, TN comes down to three things: a clear diagnosis, the right parts on the truck, and a door that is balanced and safety-tested when we finish. Stripped drive gears replaced so the motor moves the door again.
Is it time for opener gear & sprocket replacement?
- The motor hums or runs but the chain or belt doesn't move
- Grinding from inside the opener
- Plastic shavings under the motor
Why this happens
- A heavy, out-of-balance door wearing the gear
- Age and wear on the nylon gear
Safe checks before you call

Opener Gear & Sprocket Replacement in Erwin, TN
A closed garage in a Tennessee summer gets very hot, which shortens the life of opener circuit boards, capacitors and photo-eye sensors. Storms add power surges, so a surge protector is cheap insurance.

Opener Gear & Sprocket Replacement: frequently asked questions
How much does opener gear & sprocket replacement cost in Erwin, TN?
Opener Gear & Sprocket Replacement typically costs $125-$275 including parts and labor, and usually takes about 1 hour. The exact price depends on your door and the parts it needs, and you get it before any work starts. Call (833) 435-8883 for a quote.
Can you do 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 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. Ask for the warranty details in writing with your quote.
Are your technicians licensed and insured?
Our technicians are insured, and where Tennessee or Erwin 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.
