This high temperature control is a manual reset control
which senses the temperature of the shortening. If the
shortening temperature exceeds the safe operating
limit, this control switch will open and shut off the heat
to the frypot. When the temperature of the shorten-
ing drops to the safe operating limit, the control must
manually be reset.
Before replacing a high temperature limit control, check to
see that its circuit is closed.
The shortening temperature must be below 330°F
(192°C) to accurately perform this check.
1. Remove electrical power supplied to the fryer.
Place POWER/OFF/PUMP
switch in the OFF
position, and unplug the power cord or open the wall
circuit breaker, or electrical shock could result.
2. Remove the control panel.
3. Remove the two electrical
wires
from
the high
temperature limit control.
4. Check for continuity between the two terminals after
resetting the control. If the circuit is open, replace the
control, then continue with this procedure. (If the circuit
is closed, the high limit is not defective. Reconnect the two
electrical wires.)
Before
following
these
steps,
place
POWER/OFF/P~P
switch in the OFF position, and
unplug the power cord or open the wall circuit breaker,
or electrical shock could result.
1. If the tube is broke&i or cracked, the control will open,
