Float Switch Replacement for Manitowoc Ice Machines (Replacement 040002396) Key benefits Restores proper ice maker operation: replaces a worn or faulty float switch to help the machine enter the ice harvesting cycle and stop unwanted water flow. Prevents water loss and ice buildup: stops continuous water feed into the freezing area that causes water tank shortages and reduces the risk of large ice slabs forming in the freezer. OEMstyle fit and performance: designed to match the original switch's form and electrical connections for straightforward replacement and reliable sensing. What it does Monitors the water level in the ice machine and sends a signal to the control system to start or stop water fill and initiate harvest cycles as needed. Helps eliminate common symptoms of a failing float switch: failure to harvest, continuous filling, low tank water, and ice slab formation. Compatibility Fitment for Manitowoc ice machine models including: UD0140A, UD0140AE, UY0310W, UD0140W, UD0140WE, UD0190A, UD0190AE, UD0240A, UD0240AE, UD0240W, UD0240WE, and compatible models. Replacement for part number: 040002396 Attributes Function: Floatlevel sensing for fill and harvest control. Fit: OEMstyle replacement designed to match original mounting and electrical connections for these Manitowoc models. Size and form: Compact, designed to fit the original float location (verify against your existing part). Performance: Restores reliable level sensing and helps prevent overfill, underfill, and harvest failures. Material: Manufactured to meet standard equipment requirements (verify visually against original part). Package contents 1 x Float Switch Two to three common use scenarios Scenario 1: Your Manitowoc UD0140A stops harvesting ice and the bin fills with water instead of ice. Replacing the float switch restores proper level sensing so the harvest cycle resumes. Scenario 2: The machine continues to feed water into the freezing area, leaving the water tank low. Installing this float switch prevents continuous filling and stabilizes tank water level. Scenario 3: Large ice slabs keep forming in the freezer compartment of a UD0240W unit. A faulty float switch may be causing improper harvest timing; replacing it helps eliminate slab formation. Important note This item is a replacement part. Please compare the images and the physical characteristics of your existing float switch with this part before . If the images do not match your part, do not even if your model appears in the compatibility list.
