Garage Door Garage Door Motor Replacement St. Louis, MO
St. Louis garage door motor replacement, done by a crew that works this area daily. We see corroded springs and cables in the humid air, rusted track hardware and seized rollers, degraded weatherstripping from UV and moisture, and pitted galvanized hardware on older doors most often here, and we carry the parts to resolve them on the first visit.
In Missouri's humid subtropical region, hot, humid summers and short, mild winters, with frequent storms and moisture that lingers in the air most of the year. For St. Louis garages that translates into high year-round humidity that rusts springs, cables, and fasteners, corrosion that creeps across hardware in the muggy air, and salt-tinged coastal air that accelerates rust near the shore, so our tune-ups focus on the components that wear first under these conditions.
Across Botanical Heights, Rock Springs, Cabanne Place and Southwest Garden, what brings St. Louis homeowners to us is corroded springs and cables in the humid air, rusted track hardware and seized rollers, degraded weatherstripping from UV and moisture, and pitted galvanized hardware on older doors — and we resolve it without a second visit.
Motor replacement is the right move when the opener's motor or gear assembly has failed but the rest of the unit (logic board, rail, sensors, remotes, wall console) is still in good shape. On a 6–9 year old LiftMaster or Genie, motor or gear replacement is typically 40–60% the cost of a full opener swap and gives you another 8–10 years of life. We carry motor and gear assemblies for the major brands and most models from the last 12 years.
Sizing matters. A motor sized for a light non-insulated 8x7 door will burn out fast on a heavy insulated 16x7. We size replacements by measured door weight: 1/2 HP for light residential, 3/4 HP for standard insulated, 1.25 HPS for heavy insulated or oversized doors. If the original opener was under-sized, we recommend an upgrade rather than matching the underspec original.
After motor replacement, we re-program travel limits, re-calibrate force settings, and verify auto-reverse on an obstruction test. The full visit takes 90–120 minutes including these checks. We include a 2-year parts and labor warranty on the motor replacement.
Signs you need garage door motor replacement
Motor hums, door doesn't move
Capacitor failure (cheaper fix) or motor windings (full motor needed). Diagnostic determines which.
Burning smell during operation
Stop using the opener — motor is overheating, possibly due to gear strip or under-sized motor on heavy door.
Audible grinding from motor housing
Gear assembly stripping or bearing failure. Continued use destroys the gear; immediate service preserves a $149 gear swap vs. a $349 motor replacement.
Door moves slower than it used to
Worn motor windings can deliver less torque, causing slow travel. Diagnostic confirms motor vs. unrelated issues.
Smoke from motor housing
Severe motor failure or wiring fault — unplug immediately and call for emergency service.
Common causes & what we fix
Capacitor age
Start capacitors dry out over 7–10 years and stop providing torque to the motor. Often misdiagnosed as motor failure. $25–$89 capacitor swap usually fixes.
Gear assembly wear
Nylon worm gears strip after years of cycles. The gear, not the motor, is failing — gear replacement is much cheaper than motor replacement.
Motor winding burnout
Genuine motor failure from over-load on heavy doors or sustained operation against an obstructed door. Replacement is the fix.
Power surges
Grid events damage motor electronics. Surge protection prevents the most common failures.
Bearing failure
Motor bearings fail at 12–15 years on average. Replacement is possible but often makes more sense as full motor swap.
