SECTION 2. MAINTENANCE
2-1. INTRODUCTION
2-2. TEST INSTRUMENTS
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.
You may use two test instruments to check the electric components.
• 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).
2-3. REMOVING THE
CONTROL PANEL
A continuity light cannot be used to check coils or motors.
To replace parts located inside the fryer, you will need to remove the
control panel. The following steps provide the correct procedure.
SHOCK HAZARD
To avoid electrical shock or property damage, move the
power switch to “OFF” and disconnect main circuit breaker,
or unplug cord at wall receptacle.
1. Remove the decorative strips, located on each side of the control
panel, by removing the screw located on the bottom of each
decorative strip.

2. Control panel swings out, hinged on the left side of the panel.
When completely removing control panel, all wiring must be
unplugged from control panel. Be sure to mark wires before
removing.
3. Pulling down on the spring loaded hinge pin, pull control panel
straight out to completely remove.
4. Install control panel in reverse order.
2-4. TEMPERATURE PROBE The temperature probe determines the shortening temperature. If a
malfunction does occur, an E6 will be displayed on the digital readout.
Turn unit to OFF position, then back to COOK position. If E6 is still
displayed, the temperature probe must be replaced by following these
steps:
SHOCK HAZARD
To avoid electrical shock or property damage, move power
switch to “OFF” position and disconnect main circuit
breaker, or unplug cord at receptacle.
1. Drain the shortening from frypot.
2. Remove the decorative strips, located on each side of the control
panel, by removing the screw located on the bottom of each
decorative strip, and let control panel swing out.
593
2-2
Model OE-100
2-4. TEMPERATURE PROBE
(Continued)
4. Unplug electrical wires from control panel board that are attached
to temperature probe.
5. Using a 1/2" wrench, loosen screw nut from pot fitting and pull
temperature probe bulb straight out from pot fitting.
6. Install new temperature probe, making sure the temperature
probe extends through pot wall, up to the outer diameter of the
heating element.
Care must be taken not to extend the temperature probe
beyond this point or damage to probe could result.
Also, when installing new temperature probe, you must use
a new locking ferrule in screw nut. Snug screw nut up and
tighten 1/4 turn past this point. Do not overtighten screw
nut, or damage to probe could result.
2-5. HIGH TEMPERATURE
LIMIT
The high temperature limit is a manual reset device which senses the
temperature of the shortening. If the shortening temperature exceeds
the safe operating limit, the high temperature limit opens and shuts off
the heat to the frypot.
The high limit light then illuminates and the high temperature limit must
be manually reset.
Disconnect the two wires from the high temperature limit. Check for
continuity between the two terminals after resetting the high limit. If the
circuit is open, replace the high limit following these procedures. If the
circuit is closed, the high limit is not defective. Reconnect the two
electrical wires.
