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 number 1172472) is the electrically-controlled switch that energizes the compressor and condenser fan motor in your ICP Tempstar Heil WCH3364GKA2 heat pump. Rated at 30 amps with a 24-volt holding coil and an integrated shunt, it closes its line-voltage contacts whenever the thermostat calls for cooling or heating. A worn contactor is one of the most common causes of an outdoor unit that won't start, hums without engaging, or short-cycles. Pitted, burned, or welded contacts cause chattering, dropped voltage to the compressor, and tripped breakers.

Compatibility

Engineered as the direct OEM replacement for the ICP/Tempstar/Heil/Comfortmaker WCH3364GKA2 heat pump condensing unit. The same 30A/24V single-pole platform is shared across many ICP-family WCH-series outdoor units — verify the existing contactor's amp rating, coil voltage, and pole count against your old part before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and the main breaker. Verify zero voltage with a multimeter before touching any wiring.
Access — Remove the condensing unit's electrical access panel.
Document — Photograph every wire and terminal location before disconnecting anything.
Remove — Note the line, load, and 24V coil leads, then transfer wires one at a time. Unscrew the contactor from its mounting bracket.
Install — Mount the new contactor, reconnect each wire exactly per your photo, confirming the 24V leads land on the coil terminals.
Test — Restore power and call for cooling. Confirm the contactor pulls in cleanly 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.
