SECTION 2. MAINTENANCE
2-1. INTRODUCTION This section provides procedures for checking and replacement of the
various parts used within the unit. Before replacing any parts, refer to
Section 1, Troubleshooting. It will aid you in determining the cause of a
particular malfunction.
2-2. TEST INSTRUMENTS You may use two test instruments to check the electric compo-
nents.
• A continuity light.
• An ohmmeter.
When the manual refers to the circuit being closed, the continuity
light will be illuminated or the ohmmeter should read zero (0)
unless otherwise noted.
When the manual refers to the circuit being open, the continuity
light will not illuminate or the ohmmeter will read one (1).
NOTE
A continuity light cannot be used to check coils or motors.
2-3. REMOVING THE
CONTROL PANEL
To replace parts located inside the fryer, you will need to remove the
control panel. The following steps provide the correct procedure.
1. Place the power switch in the OFF position.
Disconnect the power cord from the wall receptacle or
power at the fuse or breaker box, or electrical shock could
result.
2. Remove the decorative strip, one located on each side of the
control panel, by removing the screw located on the bottom
of the decorative strip.

2-5. HIGH TEMPERATURE
LIMIT CONTROL
The high temperature limit control is a manual reset control which
senses the temperature of the shortening. If the shortening temperature
exceeds the safe operating limit, this control will open and shut off the
heat to the frypot.
The high limit light will then illuminate and control must manually be
reset.
Disconnect the two wires from the high limit temperature control.
Check for continuity between the two terminals after resetting the
control. If the circuit is open, replace the control following these
procedures. If the circuit is closed, the high limit is not defective.
Reconnect the two electrical wires.

to thermal sensor.
5. Using a 1/2" wrench, loosen screw nut from pot fitting and pull
thermal sensor bulb straight out from pot fitting.
6. Install new thermal sensor, making sure the thermal sensor ex-
tends through pot wall, up to the outer diameter of the heating
element.
Care must be taken not to extend the thermal sensor
beyond this point or damage of sensor could result. Also,
when installing new thermal sensor, you must use a new
locking ferrule in screw nut. Do not overtighten screw nut.
