Replacing the High Temperature Limit Control (Electric)

This high temperature control is a safety, manual reset control, which senses the temperature of the oil. If the oil temperature exceeds 425°F (218°C), this switch opens and shuts off heat to the vat, and E10 displays on control.

When the temperature of the oil drops to a safe operation, reset the high limit by pressing the reset button. The reset button is located behind the vat, in the element hinge. A small instrument, such as a crosshead screwdriver, or Allen wrench must be used to reset the high limit. This allows heat to be supplied to the vat once again.

Before replacing a high temperature limit control, check to see that its circuit is closed.
