The Manitowoc 000015209 Ice Machine Ice Thickness Probe W/ Washer is a sensing device that monitors the thickness of ice as it forms on the evaporator plate. It works by detecting when the ice reaches the desired thickness and signaling the machine to begin the harvest cycle. This process ensures uniform ice size and supports efficient operation. Supplied with a washer for secure installation, it is suitable for routine replacement or maintenance. Proper use of this probe can contribute to reliable performance, reduced waste, and consistent output in commercial ice machines.
