Pull the panel and find out.  You're going to be in there anyway, so
why waste time supposing?

The actuator has two neutral positions where it is supposed to stop,
at 180-degree positions of the big gear.  It stops there because the
switch on the bottom of the gear removes the connection to whichever
wire is powering it (yellow or white), and applies a connection to
the other one instead.  If the other wire also has power it runs for
another half-revolution, recursively.

Just before the gear gets to either stopping point, the cam that's
pushing on the actuator rod runs past its end and the rod is now free
to move in either direction.  So if the motor just pushed it out, now
you can push it back in -- and on the front doors, when you do so it
applies power to the motor which makes the gear (and all the other
motors) chase it to catch up.

Yrs,
