Genie Excelerator Garage Door Opener

Anyone know how to slow down the *opening* speed of a Genie
Excelerator Garage Door Opener?

It's way too fast for my old door, which I don't think will survive
such repeated jerks.

I love to cook with wine. Sometimes I even put it in the food.

Why didi you think it was called "Excelerator Garage Door Opener"? You
wanted fast, you got fast. The jerking is probably from not being
aligned properly.

Move to Japan, where the voltage 15% lower and should make the motor
run slower. Equally impractical: Install variable frequency drive
and a soft-start circuit to bring up the motor voltage frequency
gradually over a 1-2 second period to eliminate the jerk. You should
be able to get some of the parts to build one of these from old
computer power power supply because they all contain 700-volt
transistors (stack a bunch to increase the amp rating; MOSFETs or
those cool IGBFETS found in some newer Dell power supplies are easier
to stack).

Is there some kind of spring mechanism you can install on the arm that
goes between the opener and the door, to absorb the shock of the
initial jerk? My Stanley has a coil spring for this, and I believe it
could be changed for a softer one by removing 2 metal rods. I realize
that this isn't as simple as the VFD/soft start circuit mentioned
above.

Surprise! Surprise! Genie actually responded with a drawing showing
which resistor on the board sets the speed option. (No schematics,
just the board location.)
