Marantec 102276 Gearmotor for Select Synergy Series Openers
Marantec 102276 is a replacement gearmotor assembly for select Marantec Synergy garage door opener models. The gearmotor is the drive source inside the opener head, converting the opener command into mechanical rail movement. It is typically replaced when the motor or gearbox fails after the door balance, rail, trolley, belt or chain, and electronics have been checked. Fitment is especially important because Marantec uses different motor assemblies across Synergy 200, Synergy 300, Synergy Solo, and Synergy LC products. This part is commonly tied to Synergy 260, 270, 280, 380, Solo, and LC references, while Synergy 360 and 370 commonly point to gearmotor 102277.
Common Replacement Reasons
- Motor hums or stalls after door balance is verified
- Gearbox noise from the opener head
- Opener commands but rail drive does not move correctly

Technician Note
Do not diagnose a gearmotor by sound alone. A heavy door, broken spring, stripped belt, jammed trolley, or rail problem can make a good motor look weak. Verify the door and rail first.

Motor replacement involves internal opener service. Disconnect power before work. If there is burned wiring, board damage, a heavy door, or any uncertainty about high-voltage connections, use a qualified garage door technician.
