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 a genuine OEM definite purpose contactor for the ICP / Tempstar / Heil RGS240HDAA0AAAA gas furnace and matched condensing unit. A contactor is the electrically operated switch that energizes the compressor and condenser fan motor when the thermostat calls for cooling. A 24V control signal pulls in the coil, closing the line-voltage contacts that carry power to the load. We stock the correct OEM options for this model: part 1171554 (2-pole, 30A, 24V), 1172449 (3-pole, 40A, 24V) and 1183142 (3-pole, 60A, 24V). When a contactor fails, the most common symptoms are a system that won't start, chattering or buzzing at the contactor, pitted or welded contacts that won't release, or a humming coil that never pulls in.

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.
