Chandelier Lift Troubleshooting

I have been trying to install a new chandlier in our entry way. I am lucky that I have a chandelier lift. Or I thought I was. Tonight, I heard the chandelier lift activate all by its self. The power was on but the Key was in the neutral position so it shouldn't have wanted to move. It wasn't moving it was just that the motor shounded like it was energized. I was able to quickly get up and flip the light switch. That stopped the noise. Now everytime I flip the light switch, I hear the noise.
I completely disconnect the lift up down switch but the motor still wants to energize.
This is a Wilshire chandelier lift.
Any thoughts on what could be happening and how I could troubleshoot?
Appreciate any comments.

I have pretty much convinced myself that something on the controller board got fried somehow. I will get up there in a couple of days to see if I can remove the controller board. Hopefully, if the control board is simple enough, I will be able to come up with a repair. Any chance some one having a manual for the Whilshire Chandelier lift? I beleive they went out of business several years ago. The chandelier was originally installed in 2002

I would get up there and look at it. Hopefully it has fuses and one of them has blown.

I have never found any info for the Wilshire lift.
I have the info on the Alladin but they are different.

I am hoping to get up there Wed evening. I am going to need to build a temporary platform as there is just trusses and drywall right now. If I damage the drywall, I will have an even bigger project on my hands.

I found the Alladin lift documentation as well. It is such a simple board, I am hoping it is something I can fix.
At this point, it feels like one of the relay is stuck closed as the minute I energize the lift and lights, you can hear the motor hum.

The one thing that will be challenging is understanding how the limit switches are set up. One that stops the lift when it is at the ceiling and the other that stops when it is fully lowered.
SInce this is a rather specific problem, is there anywhere else I should look for help?

Couldn't wait. With power to the board, the motor hums pretty load and slowly rotates in clockwise direction. I tested the limit switches and they are both good.
The board is very simple.
The capacitors on the board all look good. The up/down relays are circled in the one image. I didn't have a volt meter with me so couldn't check the voltages at the motor and at the relays. If the motor is energized, am I incorrect tahat at least one of the relays i bad.

Notice that at one end of the board there are Test Up and a Test Down buttons. If I press the test up button, the motor does reverse direction but the minute I let it go, it goes back to the clockwise direction (Up). Even with the limit switchs closed. There is still power to the motor and capacitor

New list is $700 so need to get this to work.

If I can't get the board to work, I was thinking I might try using an Arduino.

If you look closely at the pictures there are 2 triacs (Black) that control the motor. Notice that th eone on the left is darker. I suspect that is the one that is fried. I ordered some replacements and will try to replace those first.

I would agree with you.

A very basic circuit. Two optoisolaters, two triacs (BTA12-600B) and a few support parts.
Not quite sure how that reverses the AC motor on two wires.
Are there more than two wires to the motor ?
Those triacs may be for the start winding.
