Ranco A30-3953-000 Ice Machine Bin Thermostat W/Bulb Holder

A temperature control component used in ice machine bins, this thermostat monitors internal conditions to manage when ice production should continue or stop. It uses a sensing bulb measuring 1/4" x 4" connected to an 84-inch capillary tube. This setup allows it to detect temperature changes within the storage bin. When the bin reaches the set condition, the thermostat sends a signal to pause ice production. This helps prevent excess ice buildup. Designed for commercial ice equipment, this thermostat supports effective bin management by responding to temperature variations during use. It is commonly found in ice machines used in restaurants, hotels, and foodservice environments where controlled ice production is necessary. The included bulb holder and mounting tabs help position the sensor correctly. This ensures accurate response and consistent system performance throughout daily use.

Equipment Compatibility:
Typical applications for Ranco Ice Machine Bin Thermostat include commercial ice makers used in restaurants, hotels, bars, and foodservice facilities where accurate bin temperature sensing is required to regulate ice production cycles and prevent overflow. This Ice Machine Bin Thermostat A30-3953-000 is compatible with commercial equipment from leading brands such as Hoshizaki, Manitowoc, Scotsman, Ice-O-Matic, Cornelius, and more, where precise bin temperature monitoring is needed to ensure controlled ice production and consistent system performance.

Brand Compatibility:
This component replaces multiple bin thermostat part numbers used across commercial ice machine systems from brands such as Hoshizaki, Ranco, and related refrigeration equipment manufacturers, where accurate ice bin temperature control is required for proper ice production regulation and overflow prevention. Complete cross-reference details are provided separately.
