on analog at 10, 100 and 1k.  On digital on continuity check.  On digital at 100.

I'm getting a tone on my meters...  No way I should be getting a tone.  That always means resistance of less than 1.

I mostly find compressor windings shorted to ground or once in a great while a open winding.
Hope you find our site helpful.

  Also 115vac applied to compressor causes 20 amp breaker to trip. 
    I can't think of anything else it could be.  The only good news was I was able to follow the trouble shooting flow charts and check that the board appears okay.  Obviously couldn't get fridge working and cool.  Just check that certain pins had the correct power.  And that the evap fan and other parts did work.

... not always   ... some meters... tone = less than 30 OHMs

yes.  Also the next step on the flow chart asks you to direct test the compressor.

It trips there as well.

yes. 
are you saying it still trips the House Breaker when  the Compressor Start relay is removed ?

I have a direct compressor start device made by robinair after i check for short or ground circuit i remove old relay to see if the compressor starts.If it does then i use a amprobe to see what the amps are.If it does not start then compressor is bad .I been using this start device that i got from G.E 30 years ago  when i work for them to start compressors .I do not think they make them any more, but what a useful device.Put as stated in forms above .You should never use or what to see a refrigerator on a G.F.I circuit.
