A Multiplex 020003957 Probe senses cooling conditions to maintain proper system balance and dependable dispensing performance.
The probe monitors ice bank conditions within the beverage dispenser so the refrigeration system can maintain the proper ice buildup for consistent cooling performance. Its design matters because accurate sensing and durable construction allow it to respond reliably in cold, wet operating conditions where precise ice level control is essential.
The probe may need replacement if the dispenser shows inconsistent cooling, improper ice bank formation or erratic refrigeration cycling that can affect beverage temperature and system efficiency. Physical signs can include corrosion, damage or loose connections and environmental signs may include repeated exposure to moisture, freezing conditions or scale buildup that could interfere with accurate sensing.
