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 single-pole contactor (part #1173690) is the electrical switch that sends line voltage to the compressor and condenser fan motor on your ICP Tempstar Heil WJH348000K000A2 heat pump. Rated for 40 amps with a 24V coil, the contactor pulls in when the 24V control signal energizes the coil and closes the contacts. Worn, pitted, or chattering contacts are a frequent cause of no-cool calls — the unit either won't start or runs intermittently.

Compatibility

A direct OEM fit for the ICP Tempstar Heil WJH348000K000A2 condensing unit and shared ICP-family platforms (Comfortmaker, Arcoaire, Heil) that use a 1-pole 40A definite-purpose contactor with a 24V coil. Confirm pole count, amp rating, and coil voltage against your existing contactor before installing.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage at the contactor line terminals with a multimeter.
Access — Remove the condenser service panel.
Document — Photograph all line, load, and 24V coil wiring before disconnecting.
Remove — Label and remove the wires, then unscrew the failed contactor from its mounting base.
Install — Mount the new contactor and reconnect the line, load, and 24V coil leads exactly per your photo.
Test — Restore power and confirm the contactor pulls in cleanly and the compressor and fan energize 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.
