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 is the genuine OEM 2-pole, 30-amp contactor with a 24V coil (part number 1171554) for the ICP / Tempstar / Heil RGS240LRAA0AAAA package unit. The contactor is the high-current relay that closes when the thermostat calls for cooling, energizing the compressor and condenser-fan circuit. Its contacts switch line voltage thousands of times per season, so they eventually pit, weld, or chatter. Typical failure symptoms include a unit that won't start on a cooling call, a loud buzzing or chattering at the contactor, contacts that stick closed (so the compressor never shuts off), and visible burning or pitting on the contact faces. Installing a fresh OEM-rated contactor restores clean, reliable switching and protects the compressor from low-voltage and single-phasing 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.
