OP, were the RED and GREEN Leds on the back of the romac opener flashing or constantly on? If so this will give an indication of what is wrong. There is a chart on the instruction manual that gives all of the codes. The manual can be downloaded if you do not have a copy. The other problem that i have seen is that the installers tend to simply wrap and tape (sometimes masking tape) the connections to the sensors. These are subject to high humidity and will corrode and and become unreliable. My solution was to break the connections, one wire at a time and use compression fittings. Hope this helps.
