HBW0777 Liftmaster garage door opener will not close unless wall button is held down. Weirdly enough it only does this in early fall to early spring for last 3 years. What can I do to fix it?


Have the wiring checked out for proper voltage and ground, when it is acting up. The seasonal change may affect the ground rod, it may not be well grounded.

I need to know the order to connect the wires


The solid white wire from each sensor goes to terminal #2 and the white wires with the black tracer go to terminal #3.

If the wall control is also connected you should end up with one white/red wire on terminal #1, 3 white wires on terminal #2 and 2 white/black wires on terminal #3.

If you haven't yet, double check the wiring on the back of the motor unit. A wire could have broken or just come loose. If your opener is new it will be in warranty.

Wiring the opener and sensors


The wall button gets the red and white wire. The safety eyes use the black and white wires. There are two types of attachments on the back of the openers. One has three screws. On this type the 1 is for the red wire, the 2 is for all white wires, and the 3 is for all black wires. The other type has four blocks and you just match the color to the wire color.
