Hi, I'm having a problem with my garage door opener. A few weeks ago I had to replaced the carriage assembly, but now I have a new problem. When I pressed the interrupter the door goes down a little bit then stops and goes up just a few inches. If I pressed the interrupter again the door will go up a little bit and the stops. Now, when I keep pressing the interrupter the door goes down about a foot and then reverses for about a couple of inches and then stops. On the opposite direction, the door will go up all the way, while I keep pressing the interrupter. I have checked the LED's and they are fine, no blinking, even I tested the door @ night to see the LED's and the were fine. I cleaned their lenses too, I checked the limit switches with an ohm meter and they were fine. Also checked with an ohm meter the RPM board (I think it is call that way) is the one besides the shaft of the motor and too it seems to be OK. I have no idea what could be wrong, anybody had this problem before? Please, any suggestions or comments would be greatly appreciated. Thanks
Norman.
