GAS COOKERS GPC, GPCB, GPCR AND GPCRB SERVICE AND PARTS CHAPTER 1: SERVICE PROCEDURES 1.1 Functional Description The GPC, GPCB, GPCR and GPCRB Gas Cookers all have a 12.7-gallon (48.1-liter) stainless steel cookpot. The water in the cookpot is heated by a high-efficiency infrared heating system that requires approximately 43% less energy than conventional burner systems to heat the same volume of water. Two self-contained burners are located beneath the cookpot. Each burner is fi

SMS III Controller The GPC, GPCB, GPCR and GPCRB controllers do not have a ten-time warm up cycle as previous models did, but instead use a Fenwal ignition module (807-4943). The module will try to light for four seconds. If unsuccessful, the blower will remain on for 15 seconds and try again. Once the burner is lit and the flame is proved, the module ends the lighting sequence. If the flame is not proved after eight tries, the module will lock out. When the controller power switch

the basket lift arms down, a cam attached to the left motor eventually loses contact with a roller- activated microswitch and power to the motors are cut. When the controller times out, logic circuits reverse the switch positions so that the motor circuit is again completed and the motors are restarted, raising the basket from the cookpot. At the fully raised position, the cam again makes contact with the microswitch, cutting power to the motors and stopping the lift in the up position.

1.2 Accessing Equipment for Servicing DANGER Moving this equipment while it is filled with hot water may cause spilling or splattering of the hot water. Always drain the cookpot before attempting to relocate this equipment for servicing. 1. Disconnect the unit from the electrical power supply, the gas supply and the water supply. 2. Disconnect any attached restraining devices. 3. Relocate the unit for service accessibility. 4. After servicing is complete, reconnect the unit to t

1.3.3 Replacing a Water-Level Sensor or the Temperature Probe 1. Drain the cookpot and disconnect the cooker from the electrical power supply. 2. Remove the screws in the upper edge of the control panel and swing the panel down. Disconnect the 15-pin connector, trouble light wires, and ground wire, and lift the panel out of the slots in the control panel frame. 3. Remove the topcap from the unit by removing the four screws (two on the front and two on each end) that secure it to the c

2. Disconnect the solenoid leads at the push-on connectors. Disconnect solenoid and regulator subassembly at the compression fittings on the water lines running to and from these components. Remove the two screws in the mounting bracket and remove the solenoid and regulator subassembly from the unit. (NOTE: If the cooker is not equipped with the optional Autofill feature, the cookpot water tube will be connected directly to the regulator and there will be no solenoid valve.) The in

Remove the six screws in the faucet mounting plate. Remove this nut to separate the faucet from the mounting plate. Disconnect water line at this compression fitting. Loosen this nut to separate the faucet from the water inlet manifold. 5. Separate the faucet from the water inlet manifold and mounting plate as shown in the illustration above. 6. Reverse Steps 1-5 to complete the procedure. 1.3.6 Replacing a Basket Lift Motor or Microswitch 1. Disconnect the cooker from the electrical pow

5. Remove the four bolts securing the motor mount to the frame, then remove the “motor and mount assembly” from the unit. NOTE: It is possible to replace a motor or the microswitch without removing the “motor and mount assembly”, but it is much more difficult. 6. Dismount the motor or microswitch as shown below and install the replacement. NOTE: The right motor dismounts in the same way as the left. Loosen setscrew in bottom of cam (bell crank) 7.

Remove these four screws. Remove these screws (on both sides) and remove backsplash and topcap. Remove screws along the top edge of control panel and dismount the panel. Remove the top connecting strip. Remove these screws to release the pots from the standoff brackets. 8. If removing the cookpot, disconnect the enrichment tubes and gas supply tubes from the burner assemblies. Disconnect the ignition cables and flame sensor wires from the ignitor assemblies on each burner. 9. Remove the bl

1.4 Troubleshooting Problems with this equipment maybe grouped into five broad categories: 1. Failure or malfunction of a Power-Supply System component. 2. Failure or malfunction of the Controller. 3. Failure or malfunction of an Autofill/Autoskim System component. 4. Failure or malfunction of a Water Heating System component. 5. Failure or malfunction of a Basket Lift System component. Sections 1.4.1 through 1.4.5 briefly explain the functioning of each of the systems mentioned above

used, add ⅛-cup of baking soda to the water each time the cookpot is emptied and refilled. NOTE: Do not use deliming solution to clean these units. Use of deliming solution will damage all stainless steel parts.) On units equipped with the Autoskim feature, a logic circuit in the controller automatically opens the solenoid valve for three seconds every minute. If the autofill feature is working properly, failure of the autoskim feature will be due to a malfunctioning controller and not

1.4.5 How the Basket Lift System Works When the start switch is pressed to start the cooking cycle, logic circuits in the controller activate the basket lift motors, lowering the basket into the cookpot. As the motors drive the basket lift arms down, a cam attached to the left motor (when viewed from the rear) eventually loses contact with a roller-activated microswitch and power to the motors is cut. When the controller times out, logic circuits reverse the switch positions so that the
