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 definite purpose contactor (part number 1066570) is the primary switching relay for the ICP/Tempstar/Heil ZAEB020CHA1 condensing unit. Rated for 40 amps with a 24-volt control coil, it energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. When the coil receives 24V from the control circuit, the contacts close and pass line voltage to the high-amperage loads. A failed contactor is one of the most common reasons an outdoor unit will not start — pitted, welded, or chattering contacts interrupt power delivery and can leave the system humming without running.

Compatibility

Always verify your existing contactor's amp rating, pole count, and coil voltage against the failed part before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter across the contactor terminals.
Access — Remove the service panel on the condensing unit to expose the control box.
Document — Photograph all line, load, and 24V coil wires before disconnecting anything.
Remove — Label and disconnect the wiring, then unscrew the old contactor from its mounting bracket.
Install — Mount the new contactor, reconnect line, load, and coil wires exactly per your photo.
Test — Restore power and confirm the contacts pull in and the compressor and fan start on a cooling call.

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.
