Have A Lift Master Hct 50110 Keeps Reversing
Comercial Operator, Model HCT50110. My problem is it keeps reversing. I removed the key circut, removed safety circut, every circutthat could hold this door open, it still keeps reversing? It shows it has an advanced reversing system and it looks to be adjustable, could this be the problem? I question this only because it is set at the factory, and has not ever been a problem for the last four years?
