My AC clicks but the compressor does not turn on. What is wrong?

Clicking from the outdoor unit without the compressor starting usually means a worn contactor. The contactor is the relay that sends power to the compressor. When its contacts are pitted or worn, it clicks but cannot establish a solid electrical connection. Other symptoms: visible pitting or burn marks on the contactor face, AC works intermittently, or buzzing from the contactor.

Overview

This is the genuine OEM definite-purpose contactor for the ICP / Tempstar / Heil WJA360000K000B1 condensing unit (OEM part 1173690, CONTACTOR 1P 40A 24V). The contactor is the high-current switch that connects line voltage to the compressor and condenser fan motor whenever the thermostat calls for cooling. Its 24V coil is energized by the control transformer; when powered, the coil pulls the contacts closed to start the unit, and releases them when the call ends. Rated for 40 amps with a single pole, it handles the inrush and run current of the outdoor unit. Contactors are a frequent wear item — the contacts pit, burn, and weld over thousands of cycles, while the coil can open or short. A failed contactor leaves the unit unable to start, stuck running, or chattering loudly.

Compatibility

Direct OEM-fit replacement for the ICP WJA360000K000B1 condensing unit and matching ICP-family builds (Tempstar, Heil, Comfortmaker, Arcoaire) that specify a 1-pole 40A contactor with a 24V coil. Verify the amp rating, pole count, and coil voltage on your existing contactor before installing.

Installation Guide

Access — Remove the service panel to expose the contactor.
Document — Photograph every line, load, and 24V coil connection before disconnecting.
Remove — Transfer wires one at a time or label them, then unscrew the old contactor from its mount.
Install — Mount the new contactor and reconnect each wire to the matching terminal per your photo.
Test — Restore power and confirm the contactor pulls in cleanly and the compressor and fan start on a cooling call.

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.
