If we push and hold the wall-mounted button, it will lower the door

lowering. Any suggestions on how to fix this problem?

That sounds like a problem with the photocell safety circuit.

Check the photocell safety circuit for alignment, dirty lenses, etc.
When our house was new, we had a problem in the summer with late
afternoon sun blinding the receiver. Had to have somebody stand and
shadow the receiver in order to close the door. Problem went away when
the olive tree in the front yard grew enough to block the late
afternoon summer sun.
