These are the genuine OEM 2-pole definite-purpose contactors for the ICP / Tempstar / Heil RGS150SEBA0AGAA unit: part 1178074 rated 2-pole 30 amp with a 24-volt coil, and part 1178211 rated 2-pole 40 amp with a 24-volt coil. The contactor is the electrically-controlled switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. When the 24V control signal energizes the coil, the contacts close and pass line voltage to the load; when the call ends, the contacts open. Over thousands of cycles the silver contacts pit, burn, and weld, while the coil can fail open or chatter. A failing contactor is one of the most common reasons an outdoor unit will not start, buzzes loudly, or runs when it should be off.
