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 30A definite-purpose contactor with a 24V coil and integrated shunt for the ICP/Heil/Tempstar WJH336000KTP0A2. The contactor is the high-current relay that switches line voltage to the compressor and condenser fan whenever the 24V control circuit calls for cooling or heat-pump operation. The built-in shunt maintains continuity on the unswitched leg. Contactors are a leading failure point: the silver contacts pit, weld, or burn from arcing and inrush current over thousands of cycles. A failed contactor shows up as a compressor that won't start, chatters, or won't shut off even after the thermostat is satisfied.

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.
