Overview

This is a genuine OEM 2-pole 30-amp contactor (part number 1171554) for the ICP / Tempstar / Heil RGS303SREA0AAAA system. A contactor is an electrically controlled switch that uses a 24V signal from the thermostat circuit to energize its coil, which pulls the contacts closed and sends line voltage to the compressor and condenser fan motor. Over time the contact points pit, burn, and weld from the inrush current of every cooling cycle. A failing contactor causes hard starts, chattering, intermittent cooling, or a unit that won't shut off because the contacts have welded closed. Replacing it with the correct 2-pole 30A 24V OEM contactor restores clean, reliable switching and protects the compressor from voltage drop and arcing damage.

My AC clicks but the compressor won’t turn on. What’s wrong?

Clicking from the outdoor unit without the compressor starting = worn contactor. The contactor sends power to the compressor. When its contacts are pitted, it clicks but can’t make solid contact. Look for: visible pitting/burn marks on the contactor face, intermittent operation, or buzzing.

Is this contactor compatible with Bryant or Payne too?

Many ICP parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. 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.
