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 40 Amp definite purpose contactor (part #1176763) is the primary switching relay for the ICP/Tempstar/Heil RHH036K0XA0AAAA heat pump. When the thermostat calls for cooling or heating, the 24V control coil energizes and pulls the contacts closed, sending line voltage to the compressor and condenser fan motor. Because it cycles every time the system runs, the contactor is one of the most common wear items in a condensing unit. Failure symptoms include a unit that won't start, chattering or buzzing at the contactor, pitted or welded contacts, a humming compressor that never engages, or intermittent operation on hot days. This is a 2-pole, 40A rated contactor with a 24V coil.

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.
