A winding that shows continuity to the compressor housing indicates:

Explanation:
This tests insulation integrity between the winding and the compressor housing. If the winding shows continuity to the housing, there is a conductive path from the winding to the metal frame, meaning the winding is effectively grounded. The housing is tied to earth ground for safety, so any connection from the winding to the housing indicates insulation failure or a fault causing a ground path. This is dangerous because the housing could become energized. It’s not an open condition, which would show no connection, and it’s not a normal condition. A shorted fault would involve winding-to-winding or winding-to-conductor paths, not a path to the housing.
