About this product
This float suspension switch sensor replacement helps restore proper water level sensing in compatible Hoshizaki commercial ice machines. The switch is designed to control ice thickness by monitoring the water level as ice forms; when the water level is depleted, it triggers the ice making cycle to support consistent harvest timing and cube formation. It is commonly used during service and preventive maintenance to address symptoms such as a float switch operating improperly, water levels overflowing or not filling enough, and smaller ice cubes during the harvest stage.
