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 contactor for the ICP / Tempstar / Heil RGS240HSAA0AAAA rooftop gas-electric package unit is the electromagnetic switch that delivers line voltage to the compressor and condenser fan whenever the 24V thermostat circuit calls for cooling. The factory configuration uses a 2-pole 30A 24V-coil contactor (part 1171554), with 3-pole 40A (1172449) and 3-pole 60A (1183142) versions available for higher-amperage builds of this chassis. Contactor contacts are a wear item - every cooling cycle arcs them slightly, and over time they pit, weld, or chatter. Replacing the contactor with the correct OEM amp and pole rating keeps switching clean and protects the compressor from short-cycling and dropout damage.

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.
