COMPRESSOR WINDING RESISTANCE

To measure start winding resistance, measure across the Common (C) and Start (S) pins.
To measure run winding resistance, meausre across the Common (C) and the Run (R) pins.

When measuring resistance between the Common (C), Start (S) or Run (R) pins to ground, meter
should read infinity.  Any resistance indicates a shorted compressor.

Specifications:

Start Winding Resistance C to S:

28 ohms

Run Winding Resistance C to R:

8 ohms

Pin Configuation:

C = Common
R = Run
S = Start
