GAS COOKERS GSMS, GBC, AND GC SERVICE AND PARTS CHAPTER 1: SERVICE PROCEDURES 1.1 Functional Description The GSMS, GBC, and GC 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 combustion chambers (commonly referred to as burners) are located beneath the cookpot.
water supply line for three seconds every minute until the option is turned OFF by again pressing the Skim switch. The operator enters a specified cooking time by pressing the number pads on the controller. When the Start switch is pressed, the controller begins to count down to zero. When the controller times out, an alarm sounds briefly, then the timer reverts to the last time entered.
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 the water supply and the gas supply. Reattach the restraining devices, and reconnect the unit to the electrical power supply. 1.3 Replacing Equipment Components 1.3.1 Replacing the Controller 1.
5. Replace the component box cover, and reinstall the controller being sure to reconnect the ground wire and trouble light wires. Reconnect the cooker to the electrical power supply. 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.
1.3.4 Replacing the Pressure Regulator or Solenoid Valve 1. Drain the cookpot and disconnect the cooker from the electrical power supply. Turn off or disconnect the water supply to the cooker. 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.
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 power supply. 2.
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. Reverse Steps 1-6 to complete the procedure. 1.3.
3. Reconnect the cooker to the gas supply and check all connections for leaks using a solution of soapy water. DANGER DO NOT use matches, candles, or other ignition methods to check for leaks. 4. When satisfied that there are no leaks, reconnect the unit to the electrical supply, and reconnect any restraints disconnected in Step 1. 1.3.8 Replacing the Cookpot or Rinse Tank NOTE: The following procedure addresses removing the cookpot or rinse tank from a GSMS unit.
10. Invert the cookpot or rinse tank on a suitable work surface and remove the salvageable components (e.g., probe block assembly, blower assembly, drain plumbing, etc.). Install the recovered components on the replacement cookpot or rinse tank, using thread sealer on all connections. 11. Reverse Steps 1 through 9 to complete the procedure. 1.4 Troubleshooting Problems with this equipment maybe grouped into five broad categories: 1. 2. 3. 4. 5. Failure or malfunction of a Power-Supply System component.
1.4.3 How the Autofill/Autoskim System Works The heart of the automatic filling (Autofill) system is a normally closed solenoid valve that opens when 24VAC is applied. The ground for the solenoid is supplied (via Pin 6 of the controller wiring harness) so long as the shorter of the two water-level sensors is not in contact with the water in the cookpot. When the water in the cookpot reaches the shorter of the two water-level sensors, the sensor is grounded.
extinguishing the burners. This process repeats as required to maintain the temperature at the setpoint programmed into the controller. The controller is the interface between the operator and the other components of the equipment. In the water heating system, its function is to control the firing of the burners. 1.4.
PROBLEM Continued from previous page. PROBABLE CAUSES C. Failed solenoid, failed computer, or broken/loose wiring. Test 1: Check sensor-lead connections on outside of cookpot and at Pin 9 of 15-pin connector and continuity of wire 71C. Test 2: Check for AC voltage at Pin 6 of 15-pin connector. Test 3: Check for at least 22VAC at solenoid end of wire 66C. Autoskim does not add water when selected (Autofill feature A. Failed controller. verified to be working correctly). A. Failed basket lift relay.
PROBLEM Burner will not light; trouble light is NOT on, blower is NOT running. PROBABLE CAUSES A. Failed 24VAC (blower) relay. CORRECTIVE ACTION A. If voltage is present, replace relay. Test: Check for 24VAC on Pin 4 of 15-pin connector. B. Failed controller. B. Replace controller. A. Failed blower centrifugal switch. A. If voltage is not present, replace blower. Test: Check for 24VAC at bottom 24VAC terminal of ignition Burner will not light; module (wire 7C). trouble light is ON, B.
PROBLEM PROBABLE CAUSES CORRECTIVE ACTION A. Controller out of calibration. A. Recalibrate simmer setpoint. B. Failed/shorted temperature probe. B. If resistance is out of specification, replace the temperature probe. Test: Check for shorted probe circuit. Probe resistance should be Water boils in simmer approximately 552 Ohms @ 60°F mode. (16°C), 655 Ohms @ 100°F (38°C), and 1000 Ohms @ 212°F (100°C). See probe resistance chart on page 1-15 for other temperatures. A. Controller out of calibration A.

APPENDIX A NOTES AND PARTS UNIQUE TO GSW/GWB VARIANTS A relatively small number of GSW/GWB variants have been manufactured. These two variants are very similar to the GC cooker. The principal differences are the use of a thermostat control rather than a computer and button-type water level sensors in the cookpot as opposed to the rod-type used in the GC cooker. There are also minor differences in the water supply systems. Most of these units have been manufactured as single units.
