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 a genuine OEM 1-pole, 30-amp definite-purpose contactor (part number 1172472) for the ICP/Heil/Tempstar model WJA336000K000B1. The contactor is the electrically operated switch that sends line voltage to the compressor and condenser fan whenever the 24V control circuit calls for cooling. This unit uses a 24V coil and includes an integrated shunt, allowing one leg to remain hot for crankcase-heater or related circuits. Contactors are high-wear parts: the contact points pit and burn over thousands of cycles, and the coil can fail open. Symptoms of a failing contactor include chattering or buzzing, contacts that weld closed (unit will not shut off), or contacts that will not pull in (unit will not 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.
