The electric fryer requires two switching contactors: a primary contactor and a heat contactor. The primary contactor energizes (contacts close) any time the Power/Pump Switch is in the “Power” position and the temperature of the pot is below 420°F (215OC). The hi limit will cut the power at the primary contactor if temperatures in the cookpot exceed 420° F (215O6). The primary contactor supplies power to one side of the heat contactors.
The heat contactor is controlled by the computer controller. en the controller calls for heat, the heat contactor applies power to one side of the heating elements. When the heat contactor and the primary contactor are energized (contacts
closed), the electric heating elements heat the shortening.

2.Remove the control panel.
3.Perform a check on both contactors as follows:
E?SL | Its | |
L3 | - L3 | Open Circuit |
L2 | - L2 | Open Circuit |
Ll | - Ll | Open Circuit |
4.Check across the coil terminals: Standard Contactor - 415 ohms Mercury Contactor - 1500 ohms
