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 3-pole definite purpose contactor (part number 1172449) for the ICP / Tempstar / Heil RGS210LDAA0AGAA gas furnace system. The contactor is an electrically operated switch: when the 24V control circuit energizes the coil, the three sets of power contacts close and pass line voltage to the compressor and condenser fan motor. Rated at 40 amps per pole with a 24-volt coil, it is the workhorse that starts and stops the heavy electrical loads in the system. When a contactor fails the symptoms are unmistakable — pitted or welded contacts that keep the compressor running, a chattering or humming coil that will not pull in, or no response at all when the thermostat calls. Replacing a worn contactor restores clean, reliable switching and protects the more expensive components downstream.

Access — Remove the service panel from the control compartment.
Document — Photograph every wire and terminal position before disconnecting anything.
Remove — Label and disconnect the line, load, and 24V coil leads, then unscrew the contactor from its bracket.
Install — Mount the new contactor, reconnect each lead to the matching terminal per your photo.
Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly and the system runs.

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.
