Hoshizaki 4a1107-17 Starter Relay 3ARR3

Product Description

The HOSHIZAKI 4a1107-17 is a starter relay, model designation 3ARR3, designed for use in commercial refrigeration and ice machine applications. This relay serves as a starting component in the compressor circuit, engaging the start winding during motor startup and dropping out once the compressor reaches running speed. Refrigeration technicians and commercial appliance service pros install this part as a direct OEM replacement when the original relay fails to start or trips the compressor. It is a critical component for restoring normal ice production in Hoshizaki commercial equipment.

This relay is intended for commercial ice machine and refrigeration equipment serviced by licensed refrigeration or HVAC-R technicians. It fits within the electrical control circuit of the compressor assembly, typically mounted on or near the compressor terminals. When a unit presents symptoms such as a compressor that hums but does not start, clicks repeatedly, or fails to engage, the starter relay is a common first diagnostic target and replacement part.
