Safety Limit Feature

In addition to the standard safety controls, your Manitowoc ice machine features built-in safety limits that will stop the ice machine if conditions arise which could cause a major component failure.

Before calling for service, re-start the ice machine using the following procedure:

1.Move the ON/OFF/ WASH switch to OFF and then back to ON.

A.If the safety limit feature has stopped the ice machine, it will restart after a short delay. Proceed to step 2.

B.If the ice machine does not restart, see “Ice machine does not operate” on the previous page.

2.Allow the ice machine to run to determine if the condition is reoccurring.

A.If the ice machine stops again, the condition has reoccurred. Call for service.

B.If the ice machine continues to run, the condition has corrected itself. Allow the ice machine to continue running.
