Replace the Compressor Ohms

Replace the Compressor or Condenser

With the wires removed, Ohm the compressor terminals between C-R, C-S and R-S (Common, Start, Run).  The lowest Ohm reading should be between C-R.  The next lowest Ohm reading should be between C-S.  The highest Ohm reading should be between R-S.  On a good compressor, adding the two lower Ohm readings together should equal the highest Ohm reading.    (C/R + C/S = R/S)     Three phase motors should have the same Ohm reading between all three motor terminals ( i.e. between  terminals 1-2, 1-3, and 2-3).
