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 genuine OEM single-pole contactor (part #1172472) is the electrically-controlled switch that powers the compressor and condenser fan in your ICP/Tempstar/Heil WCH3244GKB1 heat pump. When the thermostat calls, the 24V control coil energizes and pulls the contacts closed, delivering line voltage to the outdoor unit. It's rated for 30 amps and includes a shunt for low-resistance current flow. Contactors are a leading failure point in condensing units — the contacts pit, burn, and eventually weld after thousands of switching cycles, and the coil can short or open. A failing contactor shows up as a humming or chattering outdoor unit, a compressor that won't start, or contacts that stick closed and run the unit nonstop.

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.
