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 genuine OEM definite-purpose contactor, OEM part number 1172472 (CONTACTOR 1P 30A 24V W/SHUNT), is the single-pole switching relay for the ICP/Tempstar/Heil WJA330000KTP0A1 system. It uses a 24V coil to close a 30-amp contact that powers the compressor and condenser fan whenever the thermostat calls for cooling. The integrated shunt provides the correct circuit path for the line side of the unit. Contactors are high-wear parts — the contacts arc and pit with every cycle. A failing contactor causes burnt or welded contacts, chattering, or a complete no-start condition.

Is this contactor compatible with Bryant or Payne too?

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.
