lg lsxs26326s no cool

[KIRK'S APPLIANCE]

The board has been changed because no matter what test I did I could not any codes.  Compressing ohmed and tested for ground.  Previous tech said Evap coil is cracked.  I could not find a crack. I'm going back to test pressure and put some 134 in. I'll come back and let you know what I get. I have the tech sheet but it won't upload.

Is compressor running? Did you force run via board test button? 

[KIRK'S APPLIANCE]

Yes the compressor is running.

Compressor piston could be damaged. Is the compressor hot or cool to the touch?

If compressor is running and no cooling usually a sealed system issue. When you get pressures,  if lowside is 40 to 50 psi - inefficient  compressor.  If in a vacuum - first push the test button once - if it come up out of vacuum one of your cap tubes is restricted - if it stays in a vacuum added 1/2 measured charge and watch pressures. After adding refrigerant would recommend tapping highside to check pressures, if near 200 psi you have a lowside leak.
