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 2-pole, 30-amp contactor is the primary switching relay for the ICP/Tempstar/Heil RHS090H0CA0AAA heat pump. Its 24V coil is energized by the thermostat through the control transformer; when the coil pulls in, the contacts close and feed line voltage to the compressor and condenser fan. After tens of thousands of cycles the silver contacts pit, arc, and eventually weld, and the coil can open or burn out. A failing contactor produces buzzing, chattering, hard starts, intermittent cooling, or a no-start condition. Installing a fresh contactor restores clean switching and protects the compressor from voltage-related damage.

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.
