OEM Carrier 3-Pole Contactor 60 Amp 120V Coil for Model 07EB033611 — Part# HN53HF122

This is the factory OEM replacement contactor for the Carrier 07EB033611 commercial chiller and HVAC system. The contactor serves as the high-power switching relay in your unit's electrical control circuit — when the control board sends a 120V signal, the contactor closes and delivers line voltage to the compressor and motor loads. A failed contactor is one of the most common reasons a system will not start or will drop out unexpectedly under load. Symptoms include the unit failing to energize at all, chattering or buzzing noises at the contactor, burned or pitted contacts, or the system tripping on fault immediately after a start attempt.
