SOURCE: Door goes up, Won't go down.
It sounds like the limits are out of adjustment. With the door down, rotate the down limit until it clicks. Then raise the door manually, and set the up limit until it clicks. You should be able to hear the switch 'click' when it activates. Pay attention to which way the plastic nuts are moving on the screw going up and down. That way you know which way to turn them to set it.

You are receiving interference from the digi door. You will have to return this unit and go with a different one on a different frequency. Chamberlain makes a clicker that would work well with that unit. Thanks BB
