Overview

This is a genuine OEM 2-pole, 40-amp contactor (part #1066570) for the ICP / Heil / Tempstar ZAEB030CHA1 condensing unit. The contactor is the high-voltage switch that energizes your compressor and condenser fan motor. When the thermostat calls for cooling, the 24V control circuit pulls in the contactor's coil, closing two sets of line-voltage contacts and delivering power to the outdoor unit. Rated for 40A per pole with a 24V coil, it is built to handle the inrush current of a residential air-conditioning compressor. Common failure symptoms include a unit that hums but won't start, pitted or welded contacts that keep the compressor running continuously, chattering as the coil weakens, or burnt and discolored terminals. Replacing a worn contactor is one of the most common AC service repairs and restores reliable, clean switching.
