Entry Steps Problem

Hello everyone,

The entry steps on our Thor 2016 ACE are making knocking noise after retracting. The noise is so loud that our dog tries to run away from the RV. Any ideas what may have caused this? I removed the holding pin and activated the motor, it worked without any knocking noise. Appreciate any suggestions.

We had the same issue, it’s a nylon gear that has stripped teeth, not a big deal to repair. The noise it worse than the problem.

actually the step motor assembly is easy to change and camping world usually has them, if your in a bind; Amazon has them much less money


but the plastic gear lock inside is damaged and its causing the motor to rapid cycle as it tries to lock up and shut off the motor.
mine broke the other way and i about broke a leg when it retracted when i stepped down on it


its a "genius" design


stepping on the steps before they reach full extension will or may cause the gear lock to fail


takes about 1 hr to change, 10 mm open end wrench and pair of needle nose or dykes and a few zip ties. also REMOVE power to step before you attempt repair. and make sure its full extended and fingers are not in pinch points
