ICP Contactor for WJA360000K000A2 — 1-Pole 40A 24V Coil | Ships Today

Overview

This OEM single-pole definite purpose contactor (Part No. 1173690) is the electrical switch that energizes the compressor and condenser fan motor in your ICP WJA360000K000A2 unit. Rated at 40 amps with a 24-volt control coil, it closes when the thermostat calls for cooling and opens when the call is satisfied. Contactors are one of the most common HVAC failure points because the contacts arc and pit every time they cycle. Symptoms of a failing contactor include a humming or chattering outdoor unit, a condenser that won't start, burnt or welded contacts, or a system that runs continuously because the contacts have fused shut.

Specifications

Compatibility

Engineered as a direct OEM replacement for the ICP WJA360000K000A2 condensing unit. Also serves as a correct replacement across the Tempstar, Heil, and Comfortmaker family where a 1-pole 40A 24V contactor is specified. Always verify your existing part number and coil voltage before ordering.

Installation Guide

1. Safety First — Disconnect power at the breaker and the outdoor disconnect, then verify zero voltage with a multimeter.
2. Access — Remove the condenser service panel.
3. Document — Photograph all line, load, and coil wires before disconnecting.
4. Remove — Note that the capacitor may hold a charge; discharge it safely, then transfer wires one at a time from the old contactor or label them.
5. Install — Mount the new contactor, reconnect each wire to its matching terminal per your photo.
6. Test — Restore power and confirm the contactor pulls in on a cooling call and the compressor and fan start.

Signs You Need a Replacement
