If your RV step is retracting or extending only part of the way or won't stay retracted while traveling or the motor continues to run with a clunking or grinding noise after the step is retracted then it is likely that the transmission/gear in the motor needs to be replaced. A common failure inherent to the RV Step entry motor is the breakage of the plastic Gear. Over time the plastic Gear get stripped and Entry step stop working. Our Premium Repair kit s the only solution which solves all of these issues without purchasing expensive motor. This is a project you can do by your self. Please compare your existing motor with the pictures so you can order the correct Gear for your RV.
