1 SAFETY
1.1 Danger
Repairs may be carried out by an electrician only!
Improper repairs may endanger and injure the user!
To prevent electric shocks, always comply with the following
information:
• If the appliance is faulty, the housing and frame may be live!
• Do not touch any modules in the appliance, even modules can be
live!
• Before commencing repairs, always disconnect the appliance from
the power supply!
• If tests have to be performed while the appliance is live, always
use a residual-current-operated circuit-breaker!
• The protective conductor connection must not exceed the standard
values! This connection is extremely important for personal safety
and function of the appliance!
• When repairs are complete, conduct a test in accordance with
VDE 0701 or national regulations!
• When repairs are complete, conduct a function test!
• When repairs are complete, conduct a leak rate test!
1.2 Caution!
Always comply with the following instructions to prevent damage to
the appliance or to components:
• Comply with ESD instructions!
• Never attempt repairs by randomly replacing components!
• Always proceed systematically and follow the troubleshooting
instructions!
• Do not test the high-voltage circuit while the appliance is running –
Danger of death -!
• Always discharge the high-voltage capacitor before testing!

1.3 Leak test (leak detection measurement)1.3 Leak test (leak detection measurement)
The leak rate is the microwave energy which escapes despite the
intact sealing systems.
The leak rate is the microwave energy which escapes despite the
intact sealing systems.
The leak rate is measured as an energy density with suitable
measuring instruments at a distance of 5 cm. The unit of
measurement is mW/cm2.
The leak rate is measured as an energy density with suitable
measuring instruments at a distance of 5 cm. The unit of
measurement is mW/cm
The limiting values for the permitted measured values, as well as
the measurement conditions, have been specified in the VDE
regulation 0700/Part 25 and are as follows:

Set to insulation resistance.
2 COMPONENTS
2.1 High-voltage diode
Blocking direction = infinite.
The high-voltage diode can be tested like a standard diode.
Use an EHG tester for this.
• Full continuity in conducting direction.
• Infinite in blocking direction.
Set to insulation resistance.
Conducting direction = full continuity.
