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 definite purpose contactor (ICP part number 1173690) is the switching relay that energizes the compressor and condenser fan in your ICP / Tempstar / Heil WPG3602115RKB1 packaged unit. When the thermostat calls for cooling, the 24V control circuit pulls in the contactor coil, closing a single set of 40-amp line-voltage contacts to start the compressor. Rated at 40A with a 24V coil, it handles the high inrush current of the compressor on every cycle. Failure symptoms include a system that won't start, chattering or buzzing at the contactor, pitted or welded contacts that keep the compressor running, or a humming coil that won't pull in. Replacing a worn contactor restores reliable, clean switching and protects the compressor from damaging voltage drops.

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.
