My step motor failed after about a year of use. My mechanic[ kidding of corse] said once a year you change the oil and the step motor.What you need to do is open the cover on the motor,remove the plastic ball berings and replace them with steel bearings.The mechanic told me now the motor will last for ever. The motor is manufactured with cheap plastic bearings that get out of round ,cause the step to shudder then eventually quit.
I guess I am into easy fixes and the magnet was difficult to hold in place and shut the door without the stairs opening! I simply purchased a small switch wired it to the magnet sensor so I could over ride the door sensor. Now I can open the door make sure I have room to open and if not just hit switch!
