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 OEM single-pole definite purpose contactor (part #1172472) is the electrical switch that energizes the compressor and condenser fan in your ICP Heil Tempstar WCH3182GKR2 heat pump. Rated at 30 amps with a 24-volt coil and an integrated shunt, it closes when the thermostat calls for heating or cooling and passes line voltage to the outdoor unit. Contactors fail from arcing, pitted or welded contacts, and burned coils. Common symptoms include a humming or chattering outdoor unit, a compressor that will not start, contacts that stick closed so the unit never shuts off, or visible burning around the terminals.

Compatibility

Engineered as the direct OEM replacement for the ICP Heil Tempstar WCH3182GKR2 condensing unit. The same 1172472 contactor is shared across many ICP-family WCH-series heat pumps and air conditioners. Confirm your existing contactor is a 1-pole 30A 24V coil unit before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage at the contactor terminals with a multimeter.
Access — Remove the service panel from the condensing unit to expose the control compartment.
Document — Photograph all line, load, and 24V coil wires before disconnecting anything.
Remove — Label and disconnect the wires, then unscrew the old contactor from the mounting bracket.
Install — Mount the new contactor, reconnect each wire to its matching terminal per your photo, and confirm the 24V coil leads are landed.
Test — Restore power, call for cooling, and verify the contactor pulls in and the compressor and fan start.

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

Clicking from the outdoor unit without the compressor starting = worn contactor. The contactor sends power to the compressor. When its contacts are pitted, it clicks but can’t make solid contact. Look for: visible pitting/burn marks on the contactor face, intermittent operation, or buzzing.

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.
