OVEN TESTS 15.4
Enter Service mode (Servicing section). 15.4.1
Select the down arrow to display the individual 15.4.2
Oven tests (A) for the oven to perform.
Microwave Power Test 15.5
Measuring the power output.
Note: The power output is established under IEC
705 standard method which is only workable in
Laboratory controlled conditions. Power output is also
affected by line voltage under load, so this test is an
approximation only.
Ensure the oven is cold, then enter Service mode 15.5.1
to bypass oven preheating.
Select Visual View (B) to check the oven cavity 15.5.2
temperature reading is as close to 0°C as possible.
Fill a microwave safe container (glass or plastic) 1
with one litre (1.78 pints) of tap water at about
20°C (68°F).
Measure and record the water temperature in
2
the container using a thermometer capable of
reading ±0.1 degree increments.
Place the container centrally inside the oven.
3
Select ‘Microwave Power Test’ (C) from the 4
service mode tests. (Microwave power 100% for
63 seconds, fan minimum).
When the countdown has finished, remove the
5
container from the oven, immediately stir with
a plastic implement and measure the water
temperature.
Calculate the temperature rise of the water (end
6
temperature minus the start temperature).
If the temperature rise is outside these limits:
Check the microwave circuit and components, ●
(Testing Components section).
The Temperature Rise should be:
20°C (68°F) ±5%
