Hi. As the title says my electric garage door is stuck closed. When i press the fob to open it the box in the garage makes 4 beeps. There are up and down buttons on the box and the same thing happens when i press those so its not the fob. The door is Teleco brand, not much on google, a manual but nothing about error codes. I have electric power working to the garage and that is working ok and the light on the box is working. Any advice?
