PRODUCT OVERVIEW
Jackson 5930-004-33-12 Thermostat is an original Jackson replacement component engineered for commercial dishwashers, supporting efficient operation, consistent results, and reduced downtime in busy kitchens.

Details
Part# 5930-004-33-12 is an OEM high-limit thermostat with automatic reset function for Jackson warewashing equipment, rated at 220 degrees Fahrenheit. This critical safety component automatically cuts heating when water temperature reaches dangerous limits, then restores power when temperature drops safely, protecting equipment from thermal damage and preventing safety hazards.
High-limit thermostats with automatic reset fail when the reset mechanism sticks, the bimetallic element degrades, or electrical contacts become corroded. Failed thermostats may remain stuck in the open position, completely cutting heating and stopping equipment operation, or fail to reset, leaving equipment unable to reheat after temperature spike. This creates either operational downtime or dangerous temperature escalation and safety risks.
Licensed technicians must perform replacement following proper electrical lockout and safety procedures. Cool equipment completely before accessing the high-limit thermostat and verify automatic reset functionality. After installation, test the reset mechanism by allowing water to cool naturally and observing that heating power restores at the proper temperature. Document all safety testing for maintenance records. Verify that the 220-degree trip setpoint activates correctly before returning equipment to service. Regular testing confirms the automatic reset function maintains reliable protection.
