Troubleshooting Safety Limit #1 On Koolaire Ice Machine July 08 2015, 1 Comment
Koolaire, like other Manitowoc made ice machines, come with a built in safety limit feature on the control board. This is a feature that shuts the ice machine down, if certain limits are reached, to protect the ice maker and its individual components. If the machine were not to shut down with these limits, you could potentially damage your compressor, evaporator, or electronic board. Although frustrating when the ice maker goes down, these safety limits protect your investment. This article will discuss the checklist and things you should check if your Koolaire were to shut down on Safety Limit 1.
What Does Safety Limit #1 Mean
Safety Limit #1 is activated whenever the ice machines freeze time exceeds 60 minutes for 3 consecutive cycles. If your ice machine has not made ice with 60 minutes, it's not going to. The typical freeze time should be 12-15 minutes max. Anything taking longer indicates there is a problem, or your ice machine needs to be cleaned. Either way, a shutdown is warranted after 3 cycles in a row.
