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 set fits the ICP Tempstar Heil RGS303HEAA0AAAA and switches high-voltage power to the compressor and fan loads on a 24V control signal. It includes the 2-pole 30-amp contactor (OEM 1171554) and the 3-pole 60-amp contactor (OEM 1183142), both with 24V coils. A contactor is an electromagnetic switch: when the thermostat calls, 24V energizes the coil, pulling the contacts closed to deliver line voltage to the load. Pitted, welded, or chattering contacts cause hard starts, no-cool/no-run conditions, or a system that won't shut off. Replacing with the correct OEM contactor restores clean, reliable switching and protects downstream components.

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.
