A thermocouple is attached to each element and senses oil temperature. if
temperature exceeds 425°F (218°C), a switch opens and shuts off heat to vat, and E-
10 error code is displayed. After oil temperature cools to a safe operating temperature
(15-20 minutes), high limit control must be manually reset. Reset switches are located
in the front edge of an electrical panel on the right side of the unit beside the JIB.

Open the right door, depress the raised part of the rocker switch for the affected
