Scotsman A39031-021 Ice Thickness Sensor Replacement

This ice thickness sensor is a critical sensing component for commercial ice machines that can assist in controlling the ice making cycle by determining the proper thickness of the ice. It operates by detecting ice formation on the evaporator plate and communicating with the control system to stop or start the freezing process as needed. It is a component of a low voltage control system and is a key element in maintaining ice quality and avoiding over-freezing or under-producing. If this sensor is worn or inaccurate, the ice production may be inconsistent, resulting in thin ice sheets or excessive ice build-up that can impact machine efficiency. A defective sensor can cause incorrect cycle timing and may affect overall machine performance. It is commonly found in commercial kitchens, beverage stations, hotels, and foodservice environments that require dependable daily ice production.

Equipment Compatibility:
This Ice Thickness Sensor is commonly used in commercial cube ice makers and undercounter ice machines where accurate ice thickness monitoring is required for proper ice production. This part is compatible with select Scotsman ice machine models where reliable ice level sensing and production control are necessary for normal operation.

Brand Compatibility:
This part replaces several older sensor numbers used in many Scotsman ice machines. A full list of matching part numbers is available separately for proper replacement matching.
