Model #13953627SRT - CRAFTSMAN Garage door opener The garage door opens fine, reaches the set limit point and stops moving. When the button is pushed again to close the door, it makes the click noise, the light turns on (exactly like it does before the motor starts when opening) but does nothing. The light stays on like when it is opening, not flashing like if the safety reversal sensors were detecting something in the way. If I put an object in the way and then push the button, it clicks, the light comes on, and then it flashes like it is auto-reversing, but the motor does not move in any way. I have tried adjusting the UP and DOWN limits, as well as the force adjustments for both directions, to the same result, the door will open, but will not close. Using the emergency release to unhook it from the opener, the door swings freely both open and closed (the springs were replaced about two months ago) easily by hand, the door itself isn't sticking or unbalanced at any point.
There is an led light on the motor head. If it is flashing in sequence resubmit with that information for me. If it is flashing 5 times replace the rpm sensor. Make sure the interruptor cup is on tightly. If you can hold the button down on the wall station and the door operates then the sensors are the problem. Make sure the trolley is not stuck on the up stop bolt or the opener head too. Thanks BB
Thanks for the quick response. The LED was indeed flashing 5 times, so I replaced the RPM sensor, but it is still flashing 5 times even with the new sensor, and still behaving the same way as before. Is it possible there is a problem with the wire harness assembly leading to the RPM sensor, or did I just happen to get 2 bad RPM sensors? The wire harness clip can only attach to the sensor one way, I double checked to make sure I didn't have it on backwards or something silly like that. The interrupter cup is on tight, and when I opened the door it spun properly on the motor shaft. The trolley is not stuck on anything, though it bumped the stop bolt once when I was adjusting the UP limiter (I manually rotated the motor shaft to move it back from the bolt to make sure it wasn't stuck). I also tried holding the button, but to no result.
Is the RPM sensor the only part that could be causing this problem with the LED flashing 5 times and door moving up but not down? I checked conductivity on the wiring to the up and down limit sensors as well as from the board to the RPM sensor and they check out. This was a new RPM sensor, but it shows the same result as the old sensor.
