ICP 2-Pole 30A Contactor for RHS090S0BA0AAAA — 24V Coil | Ships Today

Overview

This OEM 2-pole, 30-amp definite-purpose contactor (part #1178074) is the switching relay that energizes the compressor and condenser fan motor in your ICP/Heil/Tempstar RHS090S0BA0AAAA heat pump. When the thermostat calls for cooling or heating, the 24V control coil pulls in the contactor's twin power poles, closing the line-voltage circuit to the outdoor unit. Contactors are among the most common failure points in an HVAC system because the contacts arc every time they open and close, eventually pitting, welding shut, or burning out the coil. Symptoms of a failing contactor include an outdoor unit that won't start, a loud hum or chatter from the contactor, contacts that stick closed so the compressor never shuts off, or visible pitting and burn marks on the contact surfaces. Rated for 30 full-load amps across two poles with a 24-volt holding coil.

Specifications

Compatibility

Direct OEM fit for ICP, Heil, Tempstar, Comfortmaker, and other International Comfort Products heat pumps and condensers, including model RHS090S0BA0AAAA. As a standard 2-pole 30A / 24V definite-purpose contactor, it also serves as a universal replacement for many 1.5–4 ton outdoor units using the same rating. Always confirm pole count, amp rating, and coil voltage against the contactor you are replacing.

Installation Guide

1. Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage at the contactor with a multimeter before touching any terminals.
2. Access — Remove the condenser unit's service/access panel to expose the contactor.
3. Document — Photograph all line, load, and 24V coil wiring before disconnecting anything.
4. Remove — Label and disconnect the L1/L2 line, T1/T2 load, and the two 24V coil leads, then unscrew the old contactor from its mounting bracket.
5. Install — Mount the new contactor, transfer each wire to the matching terminal per your photo, and confirm tight connections.
6. Test — Restore power and place a cooling/heating call; confirm the contactor pulls in cleanly and the compressor and fan energize.

Signs You Need a Replacement

• Outdoor unit fails to start or only runs intermittently.
• Loud humming, buzzing, or chattering from the contactor.
• Contacts welded closed so the compressor runs nonstop.
• Visible pitting, melting, or burn marks on the contacts or coil.
