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.

Overview

This OEM 2-pole, 30-amp definite purpose contactor (OEM part 1171554) is the electromechanical switch that energizes the high-voltage components in your ICP, Tempstar, or Heil system. When the 24V control signal from the thermostat reaches the coil, the contactor pulls in and sends line voltage to the compressor and condenser fan motor. A failing contactor is one of the most common HVAC service calls — pitted or welded contacts cause the unit to run continuously or fail to start, while a burned-out 24V coil leaves the system completely dead even though the thermostat is calling.

Compatibility

Directly fits the ICP/Tempstar/Heil RGS303LEFA0AAAA and is a common service part across many Carrier-family condensing units and packaged systems that use a 2-pole 30A 24V contactor. Always confirm pole count, amp rating, and coil voltage against the contactor being replaced.

Installation Guide

Safety First — Disconnect power at the breaker and the outdoor disconnect, then verify zero voltage with a multimeter across the line terminals.
Access — Remove the service panel on the condenser or air handler to expose the contactor.
Document — Photograph every line, load, and 24V coil wire before disconnecting anything.
Remove — Transfer wires one at a time, or label them, then unscrew the old contactor from its mounting bracket.
Install — Mount the new contactor and reconnect each wire to the matching terminal per your photo.
Test — Restore power, place a thermostat call, and confirm the contactor pulls in cleanly and line voltage passes through.

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.
