Need help with GDO. Opens by itself
I bought a house and was renovating it for months. I never had any problems. When my new tenants moved in they asked me for a garage door opener remote so I went down and bought one. I bought a Sky Link G5 for my LiftMaster Model 41A3516-1. I was having trouble programing it from the instructions and when I called the 1 800 number they were closed for the day. The next day when the company called me back they told me what they thought I had done wrong so I returned to the house to try what they suggested. My tenant told me I had left the door open but I am sure I didn't. I tried what they had told me and had no sucess again. The next day when I returned to call the company during their hours my tenant told me that I had left the door open again but I know I didn't. We determaned that the door was opening on its own. That day I managed to get the remote programed with the company but the door still keeps opening whenever it wants even when we take the battery out of the remote. I even asked my 5 closest niebours to push their buttons and it didn't open. PLEASE HELP ME. My motor unit only has a yellow learn button so I can't change any pins
Any suggestions would really help cause I don't want to buy a new opener.
