Controls heating element operation. 2 60-Minute Timer Electric timer to aid operator in timing cooking cycle. Does not control oven operation. 3 5-Hour Timer Same as 60-Minute Timer. ON-OFF Switch Controls electrical power to thermostat and fan motor. Must be in ON position for oven to operate.
SECTION 4 PRINCIPLES OF OPERATION 4.1 GENERAL 4.3.2. ON-OFF Switch The Power Saver II electric convection oven uses a carefully designed insulation system, which achieves optimal cooking heat from power consumed. A convector fan distributes heated air uniformly throughout the oven interior. Heat is supplied by electric elements, controlled by a thermostat mounted on the control panel. Control of power to the oven control circuits is provided by the ON-OFF Switch.
SECTION 5 TROUBLE-SHOOTING 5.1 GENERAL The information in this section is intended to assist both the operator and service personnel in locating the general source of problems which may occur with the Power Saver II.
