Overview

This OEM 2-pole, 30-amp definite-purpose contactor (part number 1178074) is the electrical switch that energizes the compressor and condenser fan in your ICP / Tempstar / Heil RGS102LFCA0AAA system. When the thermostat calls for cooling, the 24-volt control coil pulls the contacts closed, sending line voltage to the high-load components. A failing contactor is one of the most common reasons an outdoor unit won't start. Symptoms include a humming or chattering sound at the unit, pitted or burnt contacts, a system that runs intermittently, or a unit that fails to respond to a cooling call even though the thermostat is set correctly.

Is this contactor compatible with Bryant or Payne too?

Should I use OEM or aftermarket for my ICP contactor?

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
