When I press the remote button, I just hear a whirring sound from the motor, the garage door doesn't open. It's 10 years old, do I need to get a new unit? Any suggestions would be welcome.Thanks
Remove the cover and take a look at the drive gear. It is white nylon and is just in front of the motor. It will be very obvious if it is bad. The part number is 41A2817 and is available at any good door opener service company. It comes with instructions.
