Overview

This OEM definite-purpose contactor switches line voltage to the compressor and condenser fan motor on your ICP Tempstar Heil RHS183H0AA0AAAA heat pump. A 24-volt signal from the control board energizes the coil, pulling in the contacts that power the outdoor unit. This listing covers the 2-pole, 30-amp contactor (OEM part 1171554) and the 3-pole, 40-amp contactor (OEM part 1172449) for higher-load builds. Pitted, welded, or chattering contacts are one of the most common no-start and short-cycle complaints on RHS-series units.

Is this contactor compatible with Bryant or Payne too?

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.
