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 ICP OEM 2-Pole 30A Contactor (part number 1178074) is the electromagnetic switch that energizes the compressor and condenser fan in the ICP / Tempstar / Heil model RGS180SEEA0AAAA unit. When the thermostat calls for cooling, the 24V control coil pulls the contactor closed, sending line voltage through its two 30-amp poles to the high-voltage loads. Over time the contacts pit, arc, and corrode, while the coil can burn out — leaving the system unable to start, or causing it to chatter, buzz, or weld closed and run continuously. A failed contactor is one of the most common no-cooling service calls. This OEM-rated 2-pole, 30A, 24V-coil contactor is a direct replacement built for reliable high-amperage 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.
