How To Diagnose A Manitowoc Ice Machine August 07 2014, 5 Comments

Commercial ice machines can be intimidating, even to experienced service technicians. They can also take a long time to properly diagnose and isolate the problematic ice machine part. I'll cover some basic techniques you can use to troubleshoot your Manitowoc ice machine, before calling out an expensive service tech.

The first step is to understand how a Manitowoc ice maker works. Experts in commercial refrigeration and ice making equipment recommend following a sequence of events. This sequence of events is a layout of exactly what the ice machine should be doing at an exact time in a cycle. For example, newer modular Manitowoc ice machines will purge the water from the trough before beginning a freeze cycle. This should tell you exactly when the dump valve should be energized. Service literature is available for free from the Manitowoc Ice website, where you can find specific service help for your model ice maker.
