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.
