Overview

This ICP 2-pole, 30-amp contactor (OEM part 1171554) with a 24-volt coil is the genuine switching relay for the RGS243STAA0AAAA. A contactor uses a low-voltage 24V control signal to energize its electromagnetic coil, pulling in the contacts that send line voltage to the load. Over time the contacts pit, burn, or weld, and the coil can fail open — causing no-start conditions, chattering, or a system that won't shut off. Replacing a worn contactor with this OEM 30A unit restores reliable, full-current switching at the exact rating the RGS243 was built for.

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

Is this contactor compatible with Bryant or Payne too?

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.
