TV Lift Motor

I have a problem with the motor in my ceiling tv lift. I have 120 volts going to the motor connection but the motor does nothing. The question is, how do I get the motor out of there?



The motor goes through a square tube with three screws on each edge. If I take out these 9 screws does the tv fall out of the sky or does the cover of the square tube just lift off giving me access to the motor?



Do I have to take the tv out and all of the cables or can I leave the tv in?


I know several people have replaced their motors but I can't find any resources to give me directions.

Hypoxia is our resident expert on TV lifts. Here's a link to the previous thread. Post #2 explains the system as well as troubleshooting. Post #3 is a link to the manuals.

Quick link to files, there are 4 TV Lift files you may want to download. I had a broken metal gear in the motor which was likely caused by someone hanging from the lift. Commonly caused by a theft attempt or so I am told.

Hypoxia, I have downloaded all the manuals I could find but none of them cover the motor in any detail.



When you removed your motor, did you have to remove the TV and frame first?



Also, I have 120V going to the motor when I push the down button but the motor doesn't run. When I ohmed the motor it shows open. Is there an interlock or internal fuse in there?

I don't have any info on the motor operation other than what those downloads show. I was in the middle of a bunch of projects and travel & didn't make any other notes that I can find. I have a few photos of the gearbox. I did take the TV and frame off for access. I ordered the motor and the lead time was around 2 months. The sticker on the motor said Lift It, Inc., Made in USA,Lift It: Flip-Down Ceiling TV Lifts for LCD and Plasma Televisions, Model #LFT-23-A0020-B. The motor was around $700.

There have been a few times it didn't move up or down in the last few years.
I unplug the motor wire at controller JP3 and unplugged 120 VAC source, the relay clicks and everything starts working like normal (same symptom & cure 2X)

Are you measuring the 120 VAC at the control module or where? Do you get any indication/noise, clicking at the controller or motor when trying to raise/lower it? Have you manually lowered it? It needs to be lowered for access.

OK, that was too much fun. I didn't realize how much stuff had to come out and how heavy the motor was.
I was getting the clicks at the controller and read the 120v at the four pin connector at the controller and at the connector going to the motor.

When I disassembled the motor assembly I noticed the micro-switch for the manual opperation. When switching from manual to auto the micro wasn't deactivating. I had to adjust it a nudge. Life is good again. I just saved another $600.
Now I have to get this all back together and check out the controller. When I was checking for120v at the 4 pin I noticed that the up pin wasn't activating every time. Might have a cold solder joint somewhere.
If nothing else I now know more about this motor assy then I did yesterday at this time. I just wish that in all of these manuals that I downloaded there would have been disassembly instructions or exploded views of the motor assy itself. Would have made life a lot easier.
