Hey all, was at a p29 sanyo fault earlier. I didn't get much time to look a the outdoor as light was fading, I'm going back tomorrow.

My compressor windings were all the same resistance: 0.7 ohms
My HIC board had a reading of 298 between P and N on each phase of the inverter.

Anything else I can check?

It's a split: Spw-cr484gvh56

Thanks

you need to power down the hic board- unplug the u,v,w and + and - test resistance accross + to u,v,w then - to u,v,w then reverseleads toget more readings, all 3 sets of resistances should be the same, either continuity or infinity- ideally a analogue meter
megger the pot to earth too

Is that Hic board error fault?

If it is my advice would be to condemn it or set it on fire!!

P29 its error of board or compressor. Compressor try to start? Im from pad, dont have manual on him.

I'll give that a try thanks. Meant to add that I tested it yesterday and it's not down to earth,

No, when I was at it the compressor didn't even try to start, that's why I think it's the compressor, I think it's locked.

Thanks.
The readings from the HIC board looked good so I called the compressor. I'll update if I hear any more about the system.

Hi,
The fault P29 can come from the CT around the line of the power supply.

put an inverter checker on it to proove your hic board is ok

Change them both make more money ;-)
