Service
Repair or replace any opener — LiftMaster, Chamberlain, Genie, Craftsman and more.
Master-Tech repairs and replaces every major garage door opener brand, including LiftMaster, Chamberlain, Genie, Craftsman, Marantec, Sommer and Linear. Whether your opener hums but won't lift, reverses halfway, ignores the remote, or has stopped responding entirely, we carry the gears, capacitors, logic boards and remotes to fix most issues on the first visit.
A grinding noise is almost always a stripped main gear. Door reverses before closing? Usually misaligned or dirty safety sensors. Remote works sometimes but not always? Often a dying motor capacitor or interference from a new LED light. Opener completely dead? Could be a tripped breaker, blown fuse, or end-of-life logic board. We diagnose the root cause — not the symptom — so you don't pay for a replacement opener you don't need.
If your opener is over 10 years old, it likely lacks rolling-code security and modern safety reversal. We can replace it with a quiet belt-drive Wi-Fi opener (LiftMaster myQ, Chamberlain Smart) that lets you open, close and monitor your garage from anywhere — and integrates with Apple Home, Google Home and Alexa.
