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 2-pole, 30-amp definite-purpose contactor (part 1178074) is the electrical switch that energizes the compressor and condenser fan motor on your ICP RHS102S0AA0AAAA heat pump. When the thermostat calls for cooling or heating, the 24V coil pulls the contactor closed, sending line voltage to the compressor. Contactors are one of the most common HVAC failure points because the contacts arc and pit every cycle. Symptoms of a failing contactor include a unit that won't start, a loud chattering or buzzing at the contactor, contacts that weld shut (leaving the compressor running continuously), or pitted/burnt contact points. Installing a fresh OEM-rated 30A contactor restores clean switching and protects your compressor from low-voltage and chattering damage.

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.
