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. Each combustion chamber is fitted with special ceramic tiles that are heated by the burning
of a forced air/gas mixture. The tiles transfer their heat to the cookpot by means of infrared
radiation, providing much more constant and uniform heat dispersion over the surface of the cookpot
than do conventional burners. Because relatively less heat is lost to the atmosphere in the process,
compared to “open-burner” designs, less fuel is required to achieve and maintain a given cookpot
temperature.
Gas flow to both of the burners is regulated by one electromechanical gas valve.
Operational control of the burner system is accomplished through a solid-state SMS III Spaghetti
Magic controller. NOTE: The SMS III controller used in this model series is identical in
appearance to the SMS III controllers used in other model series, but differs internally. Use only the
part numbers listed in Chapter 2 when replacing controllers on this equipment. The GSMS is
equipped with a basket lift, and also features automatic filling (Autofill), automatic skimming
(Autoskim), a swing-away jointed faucet, and an attached 16.5-gallon (62.5-liter) rinse-tank. The
GBC model is identical to the GSMS except that it does not have the swing-away faucet and
attached rinse-tank. The GC has no basket lift, no faucet, and no rinse tank.
When the controller Power switch is pressed, a logic circuit in the controller automatically checks
the water level in the cookpot. A normally closed solenoid valve on the water supply line
automatically opens if the normal water-level sensor is not grounded by contact with water in the
cookpot. When sufficient water has been added to ground the low water-level sensor, the unit
automatically enters the SIMMER mode and remains there unless the operator presses the BOIL
mode switch or turns the unit off. When the water level in the cookpot reaches and grounds the
normal water-level sensor, the solenoid valve in the water supply line closes. Anytime the water
level in the cookpot drops below the normal water-level sensor, the solenoid valve opens to refill the
cookpot to the proper level.
While in the SIMMER mode, logic circuits in the controller monitor the temperature of the water
and cycle the burners on and off to maintain the temperature at the setpoint programmed into the
controller. (See Chapter 3 for instructions on adjusting the setpoint.) The cooker also has low-water
safety. If the water in the cookpot falls below the low water-level sensor, the controller cuts power
to the gas valve, causing it to close and cut off the gas supply to the burners.
The Autoskim feature (on units so equipped) is activated by pressing the Skim switch. When the
feature is activated, a logic circuit in the controller automatically opens the solenoid valve in the
1-1
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.
When the START switch is pressed to start the cooking cycle, logic circuits in the controller activate
the basket lift motors (on units so equipped), lowering the basket into the cookpot. As the motors
drive 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 is 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.
THE ELECTRONIC IGNITION SYSTEM
The ignition module, located in the component box, is connected to ignitor assemblies at each
burner. The ignition module performs three important functions: it provides an ignition spark,
supplies operating voltage to the gas valve, and proofs the burner flame. NOTE: GSMS/GBC/GC
units manufactured before September 2000 have two single-spark ignition modules. Those
manufactured September 2000 and later have only one dual-spark ignition module.
The ignition module contains a 4-second time delay circuit and a coil that activates the gas valve.
The ignitor assembly consists of a spark plug, an enrichment tube, and flame sensor.
At start-up, the controller power switch is placed in the ON position, supplying approximately
12-volts DC to the heat control circuitry in the controller. If the controller senses the correct
operating parameters (i.e., the correct water level in the cookpot), it sends a signal to the 24VAC
relay in the component box to close the blower contacts. This supplies line voltage to the blower
motor. A centrifugal switch in the blower closes if the blower is operating correctly, which allows
24VAC to flow through the closed contacts of the 24VAC relay to the ignition module.
Circuitry in the ignition modules sends 24VAC to the gas valve. Simultaneously, the module causes
the ignitors to spark for 4 seconds to light the burners. A flame sensor for each burner verifies that
the burner is lit by measuring the flow of microamps through the flame. If the burner does not light
(or is extinguished), current to the ignition module is cut, preventing the gas valve from opening,
and the ignition module “locks out” until the controller power switch is turned off and then back on.
A probe monitors the temperature in the cookpot. When the programmed setpoint temperature is
reached, resistance in the probe causes the heat cycle circuitry in the controller to cut off current to
the 24VAC relay, thus cutting line voltage to the blower. This cuts the 24VAC to the ignition
module, causing the gas valve to close.

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.
Section 1.4.6 contains troubleshooting guides that provide systematic procedures to isolate and
identify the specific source of a problem. A wiring diagram is located at the end of the chapter.
1.4.1 How the Power-Supply System Works
Line voltage is supplied to the system via a power cord that is plugged or hard-wired into the store’s
electrical service. The power cord is connected to pins 1 and 5 of an 8-pin terminal block. Line
voltage is supplied to a 24VAC transformer from pins 2 and 8 of the terminal block. Pin 7 supplies
24VAC to a heat relay, which controls line voltage to the blower motor and 24VAC to the gas valve
via the ignition module. The transformer supplies 24VAC to the controller, to the coils of the
24VAC relay, and to the solenoid valve on units equipped with the Autofill option. On units
equipped with basket lifts, line voltage is supplied to a 24VDC basket lift relay from pin 6 of the
power cord terminal block. Line voltage to the basket lift motors is supplied via the basket lift relay.
1.4.2 How the Controller Works
The SMS III controller provides the interface between the operator and the system components. The
controller is powered by 24VAC supplied through Pins 1 and 2 of the wiring harness. Internal circuitry senses the water level and water temperature. Depending upon the conditions sensed, the controller energizes or de-energizes the solenoid valve to control water level and the 24VAC relay to
control burner firing to control water temperature. The controller also controls the lowering and
raising of the basket lift, and activates an audible alarm to signal the operator that a cooking cycle
has completed. A rectifier in the controller converts 24VAC to the 24VDC required by the basket
lift relay. The controller signals for heat via Pin 4, grounds the solenoid valve via Pin 6, and senses
water level via Pins 7 (low) and 9 (full). The temperature probe connects to Pins 13 and 14. The
basket lift relay connects to Pins 10 and 12. The sound device connects to Pin 11.
1-9
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. This
causes the controller to break the solenoid ground, closing the valve. Starch or lime build-up on the
sensor may keep it from grounding, therefore always make sure the sensor is clean and its lead (Pin
9 of the controller wiring harness) is firmly connected. Also, in order for the sensor to ground, there
must be some mineral content in the water (pure water is non-conductive). Consequently, the unit
will not operate correctly with distilled, highly filtered, or deionized water. If water of these types is
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 the solenoid valve. (Proper
operation of the Autofill feature can be determined by draining water from the cookpot until the
water level is below the shorter of the two water-level sensors. If the solenoid valve opens and then
closes when the water in the cookpot again reaches the sensor, the Autofill feature is working
properly.)
1.4.4 How the Water Heating System Works
To prevent lighting the burners when there is no water in the cookpot, these units are equipped with
a low-water-level sensor (the longer of the two water-level sensors). This sensor must be grounded
by contact with water in the cookpot before the control circuitry will allow firing of the burners.
Starch or lime build-up on the low-water-level sensor may keep the sensor from grounding, therefore
always make sure the sensor is clean and its lead (Pin 7 of the controller wiring harness) is firmly
connected. Also, in order for the sensor to ground, there must be some mineral content in the water
(pure water is non-conductive). Consequently, the unit will not operate correctly with distilled,
highly filtered, or deionized water. If water of these types is 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.)
In addition to the low-water-level sensor discussed above, the water heating system has three more
parts: the electronic ignition system, the temperature probe, and the controller.
The electronic ignition system controls firing of the burners. See Page 1-2 for a complete
description of this system.
The temperature probe is used only when the unit is in the simmer mode. When the simmer mode
is selected, logic circuits in the controller monitor the temperature of the water. When the water
temperature drops below the simmer setpoint, the controller closes the heat relay, causing the
burners to fire. When the water temperature reaches the setpoint, the controller opens the heat relay,
1-10
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.
1.4.5 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 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 raised position.
