Overview

This is a genuine OEM single-pole contactor (Part No. 14306504) for the ICP/Tempstar/Heil YF018G condensing unit. The contactor is the electromagnetic switch that energizes the compressor and condenser fan motor on a call for cooling. A 24V signal pulls in the coil, closing the 14-amp rated power contacts and feeding line voltage to the compressor. Failed contactors commonly cause an outdoor unit that hums but won't start, pitted or welded contacts that keep the compressor running after the thermostat is satisfied, or a chattering coil from weak control voltage. Installing a fresh contactor restores dependable switching and prevents the short-cycling that damages compressors.

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.
