Warning and Safety Instructions
1 General
Information
Danger!
Normally when the oven is switched off, the built-in discharge resistors in
the high-voltage capacitors discharge the capacitors.
For safety reasons, it is important to ensure that this discharge
takes place by always short-circuiting the high-voltage capacitors
before starting any maintenance or repair work. See Section A-2 for
instructions.
When the oven is connected to the power supply, the following
components have potentially lethal voltage applied to them:
-
High-voltage transformer (T1)
-
Capacitor (high-voltage circuit) (A4)
-
Diode (V1)
-
Protective diode (V6)
-
Magnetron
The high-voltage circuit continues to have power present even with
the appliance unplugged!
Note:
Before starting any service work, disconnect the machine from the power
supply. Service and repair work should only be carried out by qualified
persons in accordance with all appropriate local and national safety
regulations.
When carrying out measurements on an electronic connected to the
power supply, always use narrow measuring probes. Contacts are very
closely spaced and using thicker probes may cause short circuits.

Discharging the High-Voltage Capacitor
Note:
Although the high-voltage capacitor contains an internal bleed resistor to
automatically discharge the capacitor, the following procedure must be
performed!
Do not
rely on a functioning resistor!
1. Unplug the appliance.
2. Remove the screws securing the appliance lid. Remove the lid.
3. Using an insulated-handled screwdriver, touch the blade from one
terminal on the capacitor to the other terminal on the capacitor, as shown
in Figure A-1.
This may result in a rather startling “pop!”
4. Using the same insulated-handled screwdriver, touch the blade from each
terminal on the capacitor to the frame (ground) of the appliance.
