This refer all of a sudden got hot and stopped cooling. Is there and diagnosis mode to test it? Also, I know how to tell if its the control board but how do I test to see if its the inverter??

Any help would be appreciated!

Ps-everything is running, cond fan, evap fan just not the compressor. If there is power to inverter and comp isn't running would that be an inverter??

Need help.

What ohms am I looking for on compressor? Is that standard for all comp? Where do I check on the inverter board, and does it open?

PDF page 62
Check compressor for proper resistance.
9 to 11 ohms should be measured between all pins.

The actual resistance of the windings don't really matter-- if they're bad, they'll read open. You're simply looking for continuity.

Compressor checks at 11.4 across all pins. Something weird though, when I put it into diagnostic mode, all lights on display go out....3 minutes later they come on!!!! Everything is intermittently running. Sometimes evap fan will run and sometimes it won't, same with compressor. I inspected the board, front and back and saw no visual burn marks.

Test. Gives an f

You didn't say that before...classic signs of failing LV power supply on mother board...

OK. I was wrong. I took cover off and evap fan comes on and changes speed dependind on door open or closed. I heard a sound coming from inside wall of referand it sounds like something is leaking? If there was an opening in the sealed system would compressor still ohm out?

So...you have no frost on the evap coil? And the compressor is running steady?
not sure I would say it was a leak unless I tapped the system....if that leak is as large as you think, it wont hold pressure or a vacuum ...
