Removing the circulation motor
10. Component Test Procedure
Caution
1. High voltage is present at the high voltage terminal of the inverter
unit, including the aluminium heat sink.
2. It is not necessary or advisable to attempt to measure this high
voltage.
3. Before touching any oven components, or wiring, always unplug
the oven from its power source and discharge the high voltage
capacitors.
