1 - Door is in good balance and can move fairly easy with one hand through it's range when disconnected.
2 - When closing, most times the door will reverse at random points. Sometimes when first starting to close, sometimes when a foot from the bottom, etc.
3 - It doesn't appear to be related to the eye sensors. The sensor glows green as it should and if I break the beam with my foot, then the door won't even start to close.
4 - Tried setting the down and up force adjustments to maximum, with no effect.
Any ideas? I'm thinking something is shot in the internal force sensing circuit.
