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 definite-purpose contactor for the ICP/Tempstar/Heil RGS243HTFA0AAAA system is the high-voltage switch that energizes the compressor and condenser fan whenever the 24V control circuit calls for cooling. It is offered in three OEM-matched ratings — 2-pole 30A (1171554), 3-pole 40A (1172449), and 3-pole 60A (1183142) — all with a 24V coil. Pitted, welded, or chattering contacts are a leading cause of no-cool calls: the unit may fail to start, buzz loudly, or weld closed and run continuously. Select the variant that matches the pole count and amp rating stamped on your existing contactor.

Installation Guide

Safety First — Disconnect power and verify zero voltage with a multimeter at the contactor line terminals.
Access — Remove the condensing unit's electrical access panel.
Document — Photograph every line, load, and 24V coil connection before disconnecting.
Remove — Transfer wires one at a time to avoid mix-ups, then unfasten and remove the old contactor.
Install — Mount the new contactor and reconnect each wire exactly per your photo, matching pole positions.
Test — Restore power, call for cooling, and confirm the contacts pull in cleanly and the compressor and fan start.

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.
