A refrigeration appliance is provided having a first compartment to be cooled, at least one evaporator in heat transfer association with the first compartment, a defrost heater associated with the evaporator, a temperature sensor associated with the evaporator, and a control circuit. The control circuit is arranged to selectively energize the defrost heater during a defrost cycle, selectively deenergize the defrost heater during the defrost cycle, generate a timing signal while the defrost heater is deenergized during the defrost cycle, and the control circuit is arranged to receive an input from the temperature sensor, and an accumulation of time from the timing signal. A method of operating such a refrigeration appliance includes operating the evaporator to cool the first compartment, initiating the defrost cycle to defrost the evaporator, repeatedly energizing the defrost heater for a first time period and deenergizing the defrost heater for a second time period during the defrost cycle, and terminating the defrost cycle after said evaporator has reached a predetermined optimum temperature.

The control system of claim 1, wherein the second engine has a second maximum torque output associated therewith, the interface receives a second percent torque message indicating a second percentage that equals the second torque divided by the second maximum torque output, and the requested torque value is further a function of the second percentage. 3. A control system for use with at least a first engine producing a first torque and second engine producing a second torque, the control system comprising an interface between a first control computer associated with the first engine and a second control computer associated with the second engine, the first control computer controlling the second control computer through the interface such that the second torque is a function of the first torque; wherein the interface receives a first message indicating a first value from the first control computer, receives a second message indicating a second value from the second control computer, calculates an error value indicating the difference between the first and second values, and calculates a requested torque value indicating a requested torque to be produced by the second engine to cause the error value to approach zero. 4. The control system of claim 3, wherein the interface transmits a torque request message indicating the requested torque value to the second control computer. 5. The control system of claim 3, wherein the interface provides a torque request signal indicating the requested torque value to the second control computer. 6. The control system of claim 3, wherein the first value indicates a percentage that equals the first torque divided by the first maximum torque output. 7. The control system of claim 3, wherein the first value indicates a brake mean effective pressure produced by the first engine. 8. The control system of claim 3, wherein the first control computer is coupled to a first network, the second control computer is coupled to a second network, and the interface is coupled between the first and second networks. 9. A control system for synchronizing operation of a plurality of internal combustion engines, comprising: a first control computer associated with a first internal combustion engine, the control computer producing a first datum; and a second control computer associated with a second internal combustion engine; and an interface operatively coupled between the first and second control computers, the interface responsive to the first datum to provide an operational command to the second control computer, the second control computer responsive to the operational command to control the second engine so that a first relationship exists between a second torgue produced by the second engine and a first torgue produced by the first engine; wherein the first internal combustion engine has a first maximum torque output associated therewith, the first datum indicates a first percentage that equals the first torque divided by the first maximum torque output. 10. The control system of claim 9, wherein the second internal combustion engine has a second maximum torque output associated therewith, the second control computer produces a second datum indicating a second percentage that equals the second torque divided by the second maximum torque output, and the interface is further responsive to the second datum to provide the operational command to the second control computer so that the first relationship is further a function of the second percentage. 11. A control system for synchronizing operation of a plurality of internal combustion engines, comprising: a first control computer associated with a first internal combustion engine, the control computer producing a first datum
