My garage door opener is a Linear. It opens fine with either the hard wired button or remote. It will not close at all with remote. It will not close with the hard wired button unless you hold your finger on the down button until all the way down. If you only click the down button it starts down and immediately goes back up like something is in the line of sight of the safety switches.
The tow lights on the safety beam sensors are both green all the time. No red and nothing else lights up. I've checked all wiring, pulled the hard wired button apart and cleaned it. Tried to align the safety sensors and nothing will fix the problem.
Is it likely that my safety switches have gone bad? the door is only 6 years old and does not get used every day.
Best Answer
If I've found the right documentation for your opener, it says the lights should be red for a good beam. You should also get a set of flashes that indicate the fault after you press the button. Three flashes are for a sensor fault.
