POWER OUTPUT TEST
The power output of the magnetron can be
measured by the following test: (for accurate
results, the line voltage must be 120 VAC and
the oven cavity must be clean).
1. Fill a glass measuring cup with 16 oz. (453
cc) of tap water. Stir the thermometer through
the water until the temperature stabilizes.
2. Place the cup of water in the center of the
oven. Operate on HIGH for 60 seconds.
3. Stir the thermometer through the water and
record the maximum temperature.
4. Subtract the cold water temperature from
the hot water temperature. The normal result
should be a 20 - 38° F (11.1 - 21.1° C) rise in
temperature.
NOTE: Less than a 20° F (11.1° C) tempera-
ture rise may indicate an operating voltage of
less than 110 volts or a low power output from
the magnetron. Cooking time can be adjusted
to compensate for either circumstance. Re-
place the magnetron only if the water tempera-
ture rise indicates a power output well beyond
the normal result.
