Master Spa twilight 7.2 some lights are out

[Joe Benckert]

Hello, I have a Master Spa twilight 7.2 and half of the lights are out, not all of them.

Tracing the wiring, I did find a unit called SloanLED. Anyone knows what is does or what's it's for.

 

Thanks

Joe

It's the LED light controller, and it could be the problem. Post a pic.

Doesn't look like a controller to me. This one is feeding the 4 lights on the waterfall.

That is a splitter module. If it is bad it can affect just the lights in it and/or all the lights "downstream" from it.

This is the main controller module, which is likely the problem. It has 2 outputs for the splitter modules and has probably lost one. Find this and switch the two module connections. If the other half quits working but the original half starts, it is the control module. If it remains unchanged it is a splitter module.

Thanks so much for that info. The main controller main must be fine because half of the lights work and changing colors.

There are 2 circuits out of the main controller, as I said. One can be bad and the other good. So do as I suggested and switch the wires to test it. Or keep on guessing, it makes no difference to me.

Hi! 
 

I have the same problem. My light controller utilizes only one circuit. The other is capped off. The lights furthest from the keyboard. Half the lights work and the others don’t. I found one Sloan LED module but are their more? I will have to take off the other three sides to get to them if there are. Any ideas! I have the Twilight 8.2
