Hoshizaki 4A3277-01 Hot Gas Solenoid Valve Coil 120V OEM Replacement Part

The Hoshizaki 4A3277-01 is an OEM replacement hot gas solenoid valve coil designed for use in Hoshizaki commercial ice machines and refrigeration units. Operating at 120V and supplied with wire leads, this coil actuates the hot gas bypass valve within the refrigeration circuit — a critical component that controls the defrost and harvest cycle in commercial ice makers.

During the ice harvest cycle, the hot gas valve diverts compressed refrigerant gas directly to the evaporator, warming the surface just enough to release ice without interrupting the overall refrigeration process. A failed or weak solenoid coil can result in incomplete harvests, ice bridging, or a unit that fails to cycle properly. Replacing this coil restores proper valve actuation and full system performance.
