Hello,
Those Kenwoods are notorious for stripping the small sprocket in the door
gear mechanism.
I had the part number somewhere, but this is most probably your issue if the
motor is turning.
Replacing it is pretty simple.
I suggest getting a few for spares.

You say the motor works just fine.
So I assume it turns like it is trying to move the faceplate mechanism.
If so, then the stripped sprocket is probably the issue.'
Its made out of plastic, and brittle plastic at that.
Not very durable.

I was wondering if anyone has ever encountered a Kenwood D-Mask stereo
that
would not retract into its stealth mode. In particular the model I am
referring to is a KRC-805. I have the service manual etc. but of course
that
does not trouble shoot step by step. I changed out the motor controller IC
and still nothing. The motor itself works just fine it just wont rotate
the
face when the power is turned off. Any suggestions as to what to check
next?
