OVEN TESTS
1. Enter Service mode (Servicing section).
2. Select the down arrow to display the individual
Oven tests (A) for the oven to perform.
Microwave Power Test
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.
1. Ensure the oven is cold, then enter Service mode to
bypass oven preheating.
2. Select Visual View (B) to check the oven cavity
temperature reading is as close to room temperature
as possible.
a) Fill a microwave safe container (glass or
plastic) with one liter (33.56 oz) of tap water
at about 68°F (20°C).
b) Measure and record the water temperature
in the container using a temperature sensor
capable of reading ±0.1 degree increments.
c) Place the container centrally inside the oven.
d) Select “Microwave Power Test” (C) from the
service mode tests. (Microwave power 100% for
63 seconds, fan minimum).
e) When the countdown has finished, remove the
container from the oven, immediately stir with a
plastic implement and measure the water
temperature.
f) Calculate the temperature rise of the water (end
temperature minus the start temperature).
The Temperature Rise should be: 41 to 52°F rise (23
to 29°C rise)
If the temperature rise is outside these limits:
• Check the microwave circuit and components,
(Testing Components section).
