Liftmaster 41C4398A RPM Sensor Assembly Review

Average Reviews:

(More customer reviews)I have an older Craftsman Garage Door Opener. Had replaced the gears to my garage door opener and it would not work right. Would only move a foot or so and stop. Looked up information about what could possibly be wrong and it suggested that the RPM Sensor Assembly probably needed replaced. Replaced it and it now works like a charm. Was much cheaper then buying a whole new automatic garage door opener.
