  • Page 13: Power Switch

    2-4. POWER SWITCH 1. Remove electrical power supplied to fryer. To avoid electrical shock or property damage, move the POWER switch to OFF and disconnect main circuit breaker, or unplug cord at wall receptacle. 2. Remove control panel. 3. Label and remove the wires from the switch. With test instrument, check across the terminals of the switch with the switch in the ON position, then in the OFF position.

  • Page 14: I/O Power Supply Boards Assembly

    2-6. I/O POWER SUPPLY BOARD ASSEMBLY The input/output power supply board assembly distributes voltage to the various components in the fryer. The board also receives information from components in the fryer. 1. Remove electrical power supplied to the unit. To avoid electrical shock or property damage, move the POWER switch to OFF and disconnect main circuit breaker, or unplug cord at wall receptacle.

    2-7. DRAIN MICROSWITCH (Continued) 2. The following check should be made to determine if the drain microswitch is defective. a. Remove the two screws securing the microswitch to the drain rod valve bracket. b. Remove wires from the switch. c. Check for continuity across the two outside terminals of the drain switch.

  • Page 16: Heating Elements

    2-9. HEATING ELEMENTS Heating elements are available for 208, 480 and 230 volts. Check data plate to determine correct voltage. Checkout: If the shortenings temperature recovery is very slow or at a slower rate than required, this may indicate defective heating element(s). An ohmmeter will quickly indicate if the elements are shorted or open.
  • Page 17 2-9. HEATING ELEMENTS (Continued) 3. Remove the heating element wires from the terminals by removing the nuts and washers. Label each so it can be replaced on the new element in the same position. 4. Remove the bolts from the five element spreaders. The element spreaders will now pull off the elements.
  • Page 18 2-9. HEATING ELEMENTS (Continued) 13. Connect the power cord to the wall receptacle or close wall circuit breaker. Heating elements should never be energized without shortening in the frypot, or damage to the elements could result. 14. Replace the shortening in the frypot. Fig.
  • Page 19 2-10. HEATING CONTACTORS Each well of an electric fryer requires two switching contactors. The first in line is the primary contactor and the second in line is the heat contactor. When open, the primary contactor does not allow power to flow to the heat contactor. When closed, the primary supplies voltage to the heat contactor.
  • Page 20 2-10. HEATING Checkout (Power Supplied) CONTACTORS (Continued) To avoid electrical shock, make connections before applying power, take reading, and remove power before removing meter leads. The following checks are performed with the wall circuit breaker closed and the main power switch in the ON position. 1.

  • Page 22: High Temperature Limit Control

    2-12. HIGH TEMPERATURE LIMIT CONTROL The electric units, models OFE-321/2/3/4, use the same high temperature control limits as the gas units, but the mounting of the capillary tube is different on the electric units compared to the gas units. Checkout: Use the same procedure as in the High Limit Temperature Control (Gas) Section.
  • Page 23 9. Insert new 425 degree high limit, part no. 60241 and 2-12. HIGH TEMPERATURE replace screws. LIMIT CONTROL 2-11 (Continued) 10. Uncoil capillary tube, starting at control, and insert through pot fitting. To avoid electrical shock or other injury, run the capillary line under and away from all electrical power wires and terminals.
