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 the genuine OEM 2-pole definite purpose contactor for the ICP (Tempstar / Heil) RGS101HSBA0AAAA, available as a 30 Amp (OEM #1178074) or 40 Amp (OEM #1178211) unit with a 24-volt coil. The contactor is the high-voltage switch that powers the compressor and condenser fan motor when the thermostat calls for cooling; the 24V control signal energizes the coil, which pulls the contacts closed to deliver line voltage to the system. Contactors are a leading cause of no-cool calls — pitted or welded contacts, a chattering coil, or burned terminals all prevent the unit from starting reliably. Replacing it with the correct OEM-rated contactor restores clean, dependable switching.

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.
