Liquid shortening does
not reach the desired
temperature for frying.
(Continued)
3. (Continued)
the shortening temperature has
stabilized.
Measure the temperature of
the shortening by inserting an
accurate thermometer about
4 inches into the shortening to
measure its temperature. If the
temperature difference between
the measured temperature and
the thermostat setting is 10°F
or less, the thermostat can be
recalibrated.
Recalibrate the thermostat by:
(a) removing the cap on the
thermostat control knob; (b)
loosening the center brass hex
nut portion of the knob; (c) turn
the pointer portion of the knob to
the measured temperature value
of the thermostat setting.
Tighten the brass hex nut to lock
the adjustment. Replace the
cap on the knob.
4. Check the thermostat setting
against an accurate measure of
the shortening temperature. If
the temperature difference is
greater than 20°F, the thermo-
stat can
possibly be recali-
brated.
Recalibrate the thermostat by:
(a) removing the cap on the
thermostat control knob; (b)
loosening the center brass hex
nut portion of the knob; (c) turn
the pointer portion of the knob
to the measured temperature.
Tighten the brass hex nut to lock
the adjustment. Replace the
cap on the knob.
If this calibration is unsuccess-
ful, the thermostat has failed and
must be replaced.
3. Loose knob on thermostat;
or thermostat
requires calibration (temperature setting
differs by about 10°F from measured
shortening temperature).

4. Thermostat setting is more than 20°F dif-
ferent than measured shortening tempera-
ture.
