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, 40-amp contactor with a 24-volt coil (part number 1178211) is the electromagnetic switch that powers the compressor and condenser fan in the ICP / Heil / Tempstar RGS091HSCA0AAA system. When the thermostat calls for cooling, 24V from the control circuit energizes the coil, pulling the contacts closed and sending line voltage to the outdoor unit. Contactors are high-wear components — the contacts arc and pit every time they close under load, and the coil can burn out or chatter over time. Failure symptoms include an outdoor unit that won't start, a humming or buzzing contactor, contacts welded shut (unit runs constantly), or visible pitting and burnt terminals. Replacing a worn contactor restores reliable, clean switching and protects the compressor from voltage drop.

Access — Remove the unit service panel to reach the contactor.
Document — Photograph all line, load, and 24V coil wire positions before disconnecting.
Remove — Transfer wires one at a time, or label each, then unscrew the old contactor from the bracket.
Install — Mount the new contactor and reconnect each wire to the matching terminal per your photos.
Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly and the unit starts.

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.
