gar dr open 139.53..lost its counter. on test, rotates clockwise a bit, then back. Which part do I n
Part not seen on chassis assembly parts list and person on telephone says that is the only picture she has. The part that fell off is on the board of #17, RPM sensor assembly, but you cannot see it on the diagram. The part you can see is working okay. Does the part I need come with that assembly? Opener at store does not have the same parts. Part #20 sits over this little u-shaped part and it apparently counts the revolutions so that the door is lifted all the way up. This does not happen now. It seems to be a plug-in, but it may be hardwired onto the board. Someone needs to actually look at it and tell me which part to order. Shipping being what it is, I can't afford a mistake.

The rpm sensor sits on the back side of the screw gear. And the sensor on the logic board counts the revolutions. Most of the time a rpm sensor comes with the sensor and the mini board. It has 4 metal prongs and 2 plug ins. Numbers on it are p101,u101 and 14lg41oa. These are not the product numbers, but will help you identify what comes with the rpm sensor.
- 17 is the wire harness and plugs in to #16 rpm harness assembly. These are not hard wired. #18 is the shaft bearing kit and #19 is the actual rpm sensor. # 20 is the logic board. Hope this helps if not you can upload pictures here so I can have a better look. More picyures is always better than less. BB
