Overview

This is the genuine OEM 2-pole, 30-amp definite-purpose contactor (part number 1171554) with a 24V coil for the ICP / Tempstar / Heil RGS300SFBB0AGAA system. The contactor is the heavy-duty switch that the 24V control circuit energizes to send line voltage to the compressor and condenser fan. As contacts age they pit, burn, and weld — causing the unit to fail to start, chatter, or remain energized after the thermostat is satisfied. A new OEM-spec contactor restores clean, reliable switching and protects the more expensive components downstream.

Is this contactor compatible with Bryant or Payne too?

To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

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.
