Safety first: Unplug the opener and wait several minutes before opening the housing. Avoid static discharge to the circuit board.

Steps to inspect and repair:

Check power input: Verify the outlet has power using a lamp or tester. Confirm the power cord is intact and fully plugged in.
Open the opener housing: Remove the cover to access the logic/control board.
Inspect the board: Look for burnt components, darkened areas, or bulging capacitors. Check that all plug-in connectors are fully seated.
Check for loose relays: Gently press on the motor relay and other large components to ensure they are not physically loose.
Reset power: Reassemble, plug in, and test. If the 7-flash error persists and there is still no motor response, the logic board is likely defective.
Replace the logic board: Order a compatible Motorlift logic/control board for your model. Transfer any wiring one connector at a time to avoid miswiring. Mount the new board and test operation.

Opener will not start; light flashes seven times and there is no motor movement.
