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 RGS101HDBB0AAAA is a 2-pole contactor with a 24V control coil, available in 30 amp (part 1178074) and 40 amp (part 1178211) ratings. The contactor is the high-voltage switch that powers the compressor and condenser fan motor: when the thermostat calls for cooling, the 24V coil pulls the contacts closed and line voltage flows to the load. Contactors are one of the most common failure points in HVAC because the contacts arc and pit every cycle. Burned, welded, or chattering contacts cause hard starts, a unit that won't shut off, buzzing, or a compressor that gets no power at all. Replacing a worn contactor with the factory-correct 2-pole 24V part restores reliable switching.

Installation Guide

Access — Remove the service panel to expose the control box.
Document — Photograph every wire on the line, load, and 24V coil terminals before disconnecting.
Remove — Move wires one at a time to the new contactor, or label and remove them; unbolt the old contactor from the panel.
Install — Mount the new 2-pole contactor, transfer the line, load, and 24V coil wires exactly per your photo, and tighten all terminals.
Test — Restore power, call for cooling, and confirm the coil pulls in and the compressor and fan energize.

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?

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.
