Start the speedcook operation and carefully no-
tice the cycling of the halogen lamps. At power
levels of 10, both the upper halogen pair, and the
lower halogen lamp should be on 100% of the
time. However, remember that the upper rear
halogen lamp always cycles at 85% of the upper
halogen power level setting; so you will be able
to see the upper rear halogen lamp cycle off
briefly (see “
UPPER HALOGEN LAMP BALANCE -
Pg
25” for additional information).
With approximately 1 minute remaining the oven
will stop and you will be instructed to turn over
the food. Briefly open the door and close it, and
then touch the start pad to resume the remain-
der of the cooking time. At the end of the cook-
ing cycle repeat the steps above, using the same
hamburger selection (remember to once again
set the microwave power level to zero (
M=00
).
Once again pay attention to the halogen lamp
cycling. Since the oven is now hot, you should
be able to visually see thermal compensation
occurring. You will notice that both the upper and
lower halogen lamp power levels have been de-
creased by some amount.
What is important to note is that while the power
levels have been reduced (thermal compensa-
tion) the power levels which will show in the dis-
play (if you touch the power level pad while
speedcooking operation is occurring) will be the
original power levels (U=10, L=10 and M=00).
From a consumer’s point of view, if the consumer
were to cook two hamburger patties, and then
immediately cook two more patties, they could
notice the halogen lamps cycling differently with
the same selection used each time. This is per-
fectly normal when thermal compensation occurs.
The consumer’s Use & Care manual state the
following:
Page 20 - Lights (Use & Care Guide)
The halogen lights will dim and cycle on and off
during a speedcook cycle, sometimes even at
full power levels. This is normal. The oven senses
the heat level and adjusts automatically.
Page 41 - Troubleshooting, Lights (Use & Care
Guide)
Light during a speedcook cycle dims and cycles
on and off, even at full power levels. This is nor-
mal. The power level has been automatically re-
duced because the oven is hot. The oven senses
the heat level and adjusts automatically.
THERMAL PROTECTION
If oven cavity temperatures reach somewhere in
the range of 500 to 600 degrees, or if a speed-
cooking selection is chosen which exceeds 12
minutes of cooking at halogen lamp power levels
(upper and lower) greater than 7, all power lev-
els (upper, lower and microwave) will be reduced
to 7 for the remainder of the speedcooking se-
lection. This system allows for safe exterior op-
erating temperatures.
In the unlikely event that thermal protection is
required, the consumer will not notice any change
in the display readout (no power level change
indication), however, they may notice that the
halogen lamps are cycling differently than the
expected, due to the change in power levels.
As was the case with thermal compensation, the
control is provided by the thermistor and smart
board, with the thermistor sensing the oven cav-
ity temperature and the control board providing
the proper responses to lower all power levels to
7.
