Sundash 252 Fan problem - tanTALK

HollywoodTan48 · 11-28-2011, 12:29 PM

After moving a Sundash 252, the fans won't turn on.

I moved the bed, went from 240 3 phase to 240 single phase, and the electrician didn't re-wire the panel properly to convert to 120, and obviously the bed wouldn't turn on. After I went back and rewired the bed for single phase, the bed turns on and works like it should, except the fans. Both the panel fans, and the top fan don't work.

Any thoughts?

You didn't convert it properly. Both fan legs are on the same phase.

Any idea what color the fan legs are? The conversion was pretty straight forward, but I could have gotten it wrong, or maybe have a loose wire, I guess.

I take it the fan wires connect at the back panel?

Use a meter and verify the phases.

All cooling fans are 110 vac with control coming from 12 min power board, check fuse on timer power board in panel "A", I am assuming all lamps operate with timer at bed 4 digit display,white -neutral needs to be connected for timer and fans in junction box at rear of bed.
