CHECK MOTOR WINDINGS TO GROUND

Check continuity between all three terminals and the

compressor shell or copper refrigeration line. Scrape

metal surface to get good contact. If continuity is

present, the compressor windings are grounded and

the compressor should be replaced.

COMPRESSOR DRAWING LOCKED ROTOR

To determine if the compressor is seized, check the

amp draw while the compressor is trying to start.

The two likely causes of this are a defective starting

component and a mechanically seized compressor.

COMPRESSOR DRAWING HIGH AMPS

The continuous amperage draw on start-up should not

be near the maximum fuse size indicated on the serial

tag.
