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 number 1173690) is the electrical switch that powers the outdoor condensing unit on your ICP WPG4604090RKA1 system. When the thermostat calls for cooling, the 24-volt coil energizes and the contactor's 40-amp contacts close, delivering line voltage to the compressor and condenser fan motor. A failed contactor is one of the most common reasons an outdoor unit will not start, hums but does not run, or runs continuously. Over time the contact points pit, burn, or weld shut from constant arcing, and the coil can fail open. Replacing this inexpensive part restores reliable system operation.

Compatibility

Designed as a direct OEM replacement for the ICP / Tempstar / Heil WPG4604090RKA1 package unit.
