High voltages and large currents are present at the High Voltage Capacitor. It is very dangerous to work near this part when the oven is on. NEVER make any voltage measurements at the High Voltage circuits, including the magnetron filament. 18.3 High Voltage Capacitor Test 18.3.1 Disconnect and isolate the oven from the electricity supply.
19 MAINS VOLTAGE COMPONENTS 19.1 Door Interlock Adjustment Located on the door hinges are 3 safety interlock microswitches, to prevent microwave emissions escaping when the oven door is opened: The Primary (SW3) breaks the electrical supply circuit to the transformers. The Secondary (SW2) breaks the microwave circuit if the primary fails.
19.2 Convection Fan Motor & Controller 19.2.1 Convection Fan Motor. The convection motor is a 3-phase AC motor having a maximum speed of 3500 rpm controlled by a motor speed controller. The windings are thermally protected. 19.2.2 Motor Controller Provides a 3-phase AC switched mode drive to the convection motor and is controlled by a 0 - 10 Volt signal from the SRB.
