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 definite-purpose contactor (part number 1172472) for the ICP Tempstar Heil WCA3482GKA1 condensing unit. The contactor is a 1-pole, 30-amp switch with a 24-volt control coil and an integrated shunt for auxiliary control. Its job is to start and stop the compressor and condenser fan motor by closing high-voltage line power whenever the 24V thermostat circuit energizes the coil. When the coil pulls in, the contacts close and the outdoor unit runs; when the thermostat is satisfied, the coil de-energizes and the contacts open. Failure symptoms include pitted or welded contacts that keep the compressor running, chattering or buzzing from a weak coil, an outdoor unit that will not start, or visible arcing and burn marks on the terminals.

Compatibility

Engineered as a direct OEM replacement for the ICP Tempstar Heil WCA3482GKA1 air conditioner condensing unit. This contactor is also used across many ICP-family outdoor units (Tempstar, Heil, Comfortmaker) that call for a 1-pole 30A 24V contactor with shunt. Always confirm your existing contactor's amperage, pole count, and coil voltage against the unit's wiring diagram before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter at the contactor terminals.
Access — Remove the condenser service panel to expose the electrical compartment.
Document — Photograph all wire connections before disconnecting anything.
Remove — Note line, load, and 24V coil wire positions, then disconnect them and unscrew the old contactor from the bracket.
Install — Mount the new contactor, transfer each wire to the matching terminal per your photo, and confirm the shunt connection.
Test — Restore power, call for cooling, and verify the contacts pull in cleanly and the compressor and fan start.

Signs You Need a Replacement

Is this contactor compatible with Bryant or Payne too?

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.
