I'm having a problem with the garage door on my TSPP not opening fully. When the door is hit, it triggers the switch and pops the door open, but only a bit. I am guessing something is out of alignment somewhere. Long story short, it appears that the nylon rod is supposed to fire upwards, hit the little metal crossbar on the garage, and then push straight upwards and hold the garage door open (i.e. the coil is locked on). I just wanted to confirm that it's really this simple and there's not something I'm overlooking. Any help or advice would be greatly appreciated.
