Ok....that actually good news because that unit was SO POPULAR they built it from 1997 to 2007, which makes PARTs ....and Replacement units both cheap and available.
That's just the way business does business...
Now...we have to see if --
We can spin that motor so the track moves forward.
We can check the board just in front of the worm gear and see if the contacts (see Sear's parts page - that inset on the lower right showing the motor) are PAST the UP limiter.
There are several things I would check.
The motor.....move it so the unit moves down.
The limiter....I'd want to at least SEE if I can see the contacts on the board,
Lastly, I'd try to check the voltages on the motor wires. I have a voltmeter so I can do that. One is going to be ground, a second one is likely DC 24 or 36 volts, and the 3rd wire...it's likely to switch polarity between ±12 to 36 volts to change motor direction.
Thats why you hear relays click...not one but maybe two relays should click and make the motor change direction and move. If the UP relay mode is stuck....you're only going up up up and then into JAMMED up mode.
I don't know if that's what happened, but I sure would like to find some way to Power rotate that release bar about a third of the way down the track, then test it.
But I don't expect you to manually roll it down that far. I would hope that Sears maybe extended the motor shaft at one end so you can install a drill and spin the motor down.
That's probably wishful thinking....more than likely you'd end up having to remove the motor, manually move it down, test the motor by setting it on your ladder (Probably using 18 inch long jumper wires from Radio Shack or Sears)
Those are available too. But they're not readily available IN YOUR HOME right now.
Spinning the motor can be done NOW...but it's also a pain if Sears didn't give us an option to spin it easily to advance the track downward.
That's what I'm presently fighting with....
How to get the motor and track to advance far enough and perform the up/down test to see if the motor moves, see if the Limit switch went the wrong direction and caused the 5 blink failure, or see if the relays on the Logic board are the cause of the problem.
If I'm a betting man...I'd bet the logic board is the failure, not the motor.
