Overview

This genuine OEM 2-pole definite-purpose contactor (part number 1171554) is rated for 30 amps with a 24-volt coil and is built for the ICP/Heil/Tempstar RGS303LSFA0AAAA system and its companion outdoor unit. The contactor is the electrically operated switch that closes the high-voltage circuit to the compressor and condenser fan motor when the 24V thermostat call energizes the coil. After many thousands of switching cycles the silver contacts pit, burn, and eventually weld together, while the coil can short or weaken and lose magnetic pull. Symptoms include a loud buzzing or chattering at the unit, contacts stuck closed so the system never shuts off, or a unit that won't start on a cooling call. Installing this 30A 2-pole contactor restores clean, positive switching and protects the costlier compressor and motor it feeds.
