Overview

This is a genuine OEM 2-pole, 30-amp contactor with a 24-volt coil, part number 1171554, for ICP, Tempstar, and Heil equipment. A contactor is an electrically operated switch: when the 24V coil energizes on a call from the control board, an electromagnet pulls the contacts closed and passes line voltage to the load it controls. Over time the contacts arc, pit, and corrode, and the coil can weaken or burn out. Symptoms of a failing contactor include a system that will not energize, chattering or buzzing at the contactor, contacts that stick closed so the load never shuts off, or visible burning and melting on the contact points. Replacing it with the correct OEM 30A 24V unit restores clean, reliable switching and prevents nuisance no-cool or no-start calls.
