The Ranco A30-3815 Ice Bin Sensor is a specialized constant differential temperature control designed for precise bin level management in commercial ice machines. This SPST (Single Pole Single Throw) control operates within a defined temperature range of 27°F to 49°F, ensuring consistent ice production cycles and preventing overfills or evaporator freeze-ups. Featuring a 64-inch capillary lead, the A30-3815 provides the reach necessary for remote bulb placement in deep bins or complex equipment configurations. Built with a laser-welded stainless steel bellows, this commercial refrigeration thermostat delivers reliable switching performance in high-humidity environments typical of foodservice applications. As a veteran-grade ice machine parts solution, it is frequently used to replace OEM controls in systems requiring a 5.5°F fixed differential for accurate thermal response. Key Benefits for Technicians: Optimized Bin Levels: The 27/49°F temperature range allows for tight control over the ice harvest cycle, minimizing waste and equipment strain. Extended Reach: A 64" capillary tube facilitates flexible sensor bulb mounting, accommodating various bin depths and mechanical orientations. Robust Switching: The SPST switch design ensures dependable electrical contact for compressor or liquid line solenoid control. Durable Construction: Engineered with a stainless steel sensing element for resistance against corrosion and fatigue in damp ice storage areas. Common Questions & Troubleshooting: What is the fixed differential on the A30-3815? This model features a 5.5°F fixed differential, which provides the precise deadband needed to prevent short-cycling of the refrigeration system while maintaining accurate ice levels. Can this sensor be used for both ice harvest and bin level control? Yes, the Ranco A30-3815 is versatile enough to serve as a bin level safety or a harvest cycle initiator, depending on the specific equipment wiring and bulb location. Is the 64-inch capillary long enough for large modular units? In most cases, yes. The 64-inch lead is considered an "extended length" compared to standard 48-inch models, making it suitable for larger modular ice heads and tall storage bins.
