Garage door opener operates by wall button but not by any remote controls.

Safety first: Keep clear of the door while testing remotes.

Steps to fix:

• Replace remote batteries: Install fresh batteries in each Motorlift remote, observing correct polarity.
• Reprogram remotes: Press and release the LEARN button on the opener, then press and hold the remote button until the opener light blinks.
• Check antenna: Ensure the opener's antenna wire is intact and hanging freely.
• Test range: Stand within a few meters of the opener and test. If remotes only work very close, interference or a weak receiver is likely.
• Replace logic board: If no remotes can be programmed or used, replace the Motorlift logic/control board with integrated receiver.
