Kwikee 32 series
I just changed the door switch , it was fine .
Now it open and close but it seem like the motor continues pushing for three or 4 seconds ...making a tac tac tac noise ...
Would it be the sensor is not really well aligned with the magnet on the door?
thanks in advance .....
The motor , gears and controller are new .....

I had a similar problem at one time.There was a mechanism to tell it when the steps were in. I am sorry but I don't remember but I think it was on the step mechanism and made contact at full close. Look around under the step and follow any wires.

Mine made the same noise when it came in, replaced motor, computer, pull the gear box down and open it up and I bet you will find chipped off gear teeth. That was my problem.
Time for a new gear box.

I think you'll find a damaged gear or possibly the three 'buttons' that actually drive the gear are disintegrating. The motor is instructed to shut off when a certain torque value is met, as judged by the microprocessor control unit. As the gear or buttons are getting broken up the motor will just grind until a big enough piece or gear tooth comes into play. Sounds horrible but it's an easy fix. You can remove the motor/gear assembly and get it matched at an auto parts store. The typical installation uses an automotive power window motor, usually Ford. A good parts man will be your very best friend.
Just be very careful to disconnect the power to the steps before you get your hands up in there.

Like a crunching sound ?
Pull the Motor and disassemble- There is a Plastic gear in there that wear's out - Available at NAPA or O'Reilly -- Like 10 Bucs.

FWIW, there is no stop switch, the motor controller senses increased amperage draw and disconnects 12VDC electricity. Exactly like an auto electric window motor, in fact an older Ford electric window motor is a replacement option.
