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

The ICP 1173690 is an OEM single-pole 40-amp definite purpose contactor with a 24-volt coil, used to switch line power to the compressor and condenser fan motor in the WPH3362000RKA1 heat pump. When the thermostat calls, the 24V control circuit energizes the contactor coil, closing the contacts to feed 240V to the compressor. With a higher 40A contact rating, this contactor is built for the inrush and running current of larger-tonnage condensing units. Because it cycles thousands of times each season, the contactor is one of the most common outdoor-unit failure points. Pitted, welded, or burned contacts can leave the unit running nonstop, while an open coil keeps it from starting at all. Typical symptoms include a buzzing or chattering contactor, visible arcing or pitting, a compressor that will not start, or a unit that keeps running after the thermostat is satisfied.

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.
