Testing selected components (casing mounted)
Microwave Power test: Measuring the microwave power output of the magnetron(s)
Check and ensure that the appliance is cool before starting this test.
The power output is established under IEC 705 standard method which is only workable in laboratory controlled
conditions. The power output is also affected by line voltage under load, so this test is an approximation only.
1. Enter Service Mode. For details on how to access the Service Mode see Entering Service Mode in Section 3B .
2. Select 'Visual View' to check the
cavity temperature reading has
dropped to as close to 0°C as
possible. In most situations this will
be room temperature.
3. Fill a microwave safe container (glass or plastic) with one liter (approx. 2 pints) of tap water at 20°C (68°F) and
measure and record the water temperature.
4. Place the container centrally into the cavity and close the appliance door.
5. Select ‘Microwave Power Test’ from
the Service Mode tests screen
(microwave power 100% for 60
seconds, fan minimum). The test will
start running and count down will
begin on screen.
6. When the countdown has finished, remove the container from the cavity.
Immediately stir with a plastic implement and measure the water temperature.
7. Calculate the temperature rise of the water (end temperature minus the start temperature).
The temperature rise should be approximately 11°C (52.7°F) ±10% for the 800W. If the temperature rise is
considerably outside these limits check the microwave circuit and components.
It may be necessary to replace the magnetron and/or high voltage diode board / rectifier. These procedures are
described in detail in
Section 3F.
