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 definite-purpose contactor is the main switching relay for the ICP / Heil / Tempstar RHS090H0AA0AAAA. It is offered in both 30-amp (OEM 1178074) and 40-amp (OEM 1178211) ratings, each with a 24V control coil. The contactor uses the low-voltage 24V signal from the thermostat to close its line-voltage contacts and energize the compressor and condenser fan motor. Contacts are a wear item: every start cycle arcs across them, and over time they pit, burn, or weld. A failing contactor causes hard starts, chatter, a humming outdoor unit that won't run, or a unit that won't shut off. Choose the amp rating that matches the contactor currently installed in your unit.

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.
