Overview

This OEM definite purpose contactor is the primary switching relay for the ICP YA100NA1 outdoor unit. The 3-pole, 30-amp configuration (part numbers 1070823 and 607339) switches all line legs to the compressor and condenser fan, while the 1-pole 25-amp option (part number 1050699) serves single-line applications. All use a 24-volt control coil that pulls the contacts closed on a cooling or heating call. As contacts arc on every cycle, they pit and eventually weld or fail open. Typical symptoms are a unit that hums but won't start, intermittent cooling, chattering, or a compressor that keeps running after the call ends.
