Replacing the Element Safety Switch

This switch cuts power to the element when the element is raised. If a constant “E-31” “HEATING ELEMENTS ARE UP”, is displayed, when the elements are lowered into the vat, check the element safety switch.

To avoid electrical shock or property damage, move the power switch to OFF and disconnect power.
