Decide what to do if either
control failed.
If both controls pass the test,
skip this step.
If the fryer fails the first high-
limit control test but passes
the second one, the vat can be
used if that is absolutely nec-
essary. The computer controls
should be replaced as soon as
possible. Use extreme care
when using the vat in this
case.
If the fryer fails the second
high-limit control test,
do not
use the vat until the second
(mechanical) high-limit con-
trol has been replaced
. Call a
service technician immedi-
ately.
In the first test, if the heat
indicator light goes out when
the temperature is less than
410°F (210°C), that means
that the high-limit control has
activated at a lower tempera-
ture than normal. You do not
need to replace the computer
controls in this case unless
they are interfering with
proper cooking.
In the second test, if the dis-
play begins to alternate
between “HI 2” and “bad”
when the temperature is less
than 425°F (218°C), that
means that the high-limit con-
trol has activated at a lower
temperature than normal. You
do not need to replace the
high-limit control in this case
unless it is preventing you
from testing the first high-
limit control.

Discard oil.
When you have completed
both tests, allow the oil to
cool for one hour. Then dis-
card the oil. Drain the oil into
an oil removal cart. Use Neo-
prene Gloves
The oil is may be hot.

Verify high-limit controls for all
remaining fryers.
Repeat steps 1 through 10 for
all remaining fryers.
