Power Switches

Dust caps fitted on the main power switch and zone switches protect them from dust and the corrosive effect of cooking fumes.. If the dust caps are removed, or not replaced following servicing, the switches will deteriorate and have reduced life expectancy.. Replace the dust caps following servicing..

Control Circuit

Figure 4 shows the control schematic for the GC-48 unit, which has two zones.. The ignition and temperature controls for each zone are identical..
