LIMIT SWITCH SPECIFICATIONS

• Normally closed Bi-metal switch
• Open temperature: 104°F
• Close temperature: 83°F

The function of this switch is to open in the event of an
overheating condition. This bi-metal thermostat is normally
closed and does not initiate the ice harvest cycle. The ice
harvest cycle is initiated by a double throw, single pole
temperature located remotely from the ice maker assembly.
