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 fits the ICP / Tempstar / Heil RGS150LEAA0AGAA and is offered in both the 30-amp (OEM 1178074) and 40-amp (OEM 1178211) ratings, each with a 24V control coil. The contactor is the electrically operated switch that closes when the thermostat calls for cooling, sending line voltage to the compressor and condenser fan motor. Its contacts carry high current every cooling cycle, so they eventually pit, burn, or weld, and the coil can fail open. Common failure symptoms include a humming or chattering contactor, contacts that stick closed so the condenser won't shut off, or no compressor/fan operation on a cool call. Choose the amp rating that matches the part you are replacing — both share the same 2-pole, 24V-coil configuration.

My AC clicks but the compressor won’t turn on. What’s wrong?

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.
