Xbox 360 FAT 2008: Replacing Benq Motor & Troubleshooting Philips & Lite-On Drive Eject Issues

I warmly welcome. I have a problem. Recently, a friend gave me an Xbox 360 Fat version. Year of production 2008. The console was running normally until one day the drive started to go crazy. Sometimes an attempt to eject with the button gave nothing and you had to click several times and similarly with closing.
I got it and decided to run it, the more so because I have one at home with a damaged drive.
Initially I wanted to swap drives and make a spoof but found it better for me to see inside.
I dismantled the drive, no dust, no dirt etc. I came to the conclusion that I will try to replace the motor with the tray eject.
So I desoldered a working Benq motor from my drive and soldered it to the drive from my friend's console. The drive that sits here is Philips & Lite on.
Tries to see what's going on and nothing. I did not put the belt on the engine wheel to see if the engine was running. By pressing the button, the console signals Opening and pressing Closing again, but the engine is stationary.

Closing or opening is all the time, i.e. if I press eject, the opening is endless. I found that I would eject the tray by hand all the way and then the console should see that the drive is open, but it doesn't.

Please give me some suggestions:
- I can check if there is voltage to the motor to check if it is in working order, but please give me what the value should be.
- what about the opening / closing sensor? It's not that even though I opened the drive manually, it should detect that it is open?
I don't know if I understand correctly but there are two yes? They remind me a bit of a limit switch. Now the question is whether one signals closing and the other opening? Do they both signify the same? ie if the drive is open, both are short-circuited and when it is closed they are short-circuited?

You have a limit switch, check if it works, it detects if the drive is open or closed. Also check that the drive's power cable is complete.

Hello. There are two sensors. One for closing and the other for opening. At least I think so. Both are working, they close the circuits as they should.
The power cord is also functional. Every vein checked in turn.
Any other suggestion?

Defective engine controller.

I just wanted to add that I was able to fix the problem. I do not know what the thing was, but I dismantled the equipment again, to be sure, I checked the sensors for closing / opening.
I found that nothing has changed here, but I will try to fire up the console again, this time with the tray pulled out.
And that turned out to be the key to success. Previously, I always put the drive in with the tray closed and there was no reaction from the motors and the laser.
After inserting with the open tray, it is hidden and now works as it should.

Maybe cold February at the drive's power connector. Something had to go wrong, there aren't any miracles

Oh, there is no such thing, but I am glad that it started because the spoof did not want to do, the more so that I would have to translate the laser to Benq.
