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).
NOTE
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.
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.

2-3. REMOVING THE
CONTROL PANEL
(Continued)
3. Panel will now swing out with hinge located on left side of panel.
4. Pulling down on the spring loaded hinge pin, pull control panel
straight out to completely remove.
NOTE
When completely removing control panel, all wiring must be
unplugged from control panel. Be sure to mark wires before
removing.
5. Install panel board by reversing order.
2-4. THERMAL SENSOR The thermal sensor determines the shortening temperature. If a mal-
function 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 thermal sensor must be replaced by following these
steps:
1. Remove electrical power supplied to fryer.
Place POWER switch in the OFF position and unplug the
power cord or remove power from the fuse or breaker box.
2. Drain the shortening from frypot.
3. Remove two decorative strips located on each side of control
panel and let control panel swing out.

2-4. THERMAL SENSOR
(Continued)
4. Unplug electrical wires from control panel board that are attached
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 extends 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.
Snug screw nut up and tighten 1/4 turn past this point.
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.

Model OE-100
Before following these steps, place POWER switch in the
OFF position and unplug the power cord or open the wall
circuit breaker.
1. If the tube is broken or cracked, the control will open, shutting off
electrical power . The control cannot be reset.
Use replacement high limit, part no. 16337, 420 degree.
2. Drain shortening from the frypot.
3. Remove control panel per Section 2-3.
4. Remove the retainer securing the silicone gasket.
5. Loosen small inside screw nut on capillary tube.
6. Remove capillary bulb from bulb holder inside the frypot.
7. Straighten the capillary tube.
8. Remove larger outside nut that threads into pot wall.
9. Remove the two nuts that hold the high limit bracket from control
panel area.
10. Lift defective control from control panel area.
11. Insert new control and replace nuts to bracket.
12. Uncoil capillary line, starting at capillary tube, and insert through
frypot wall.
To avoid electrical shock or other injury, the capillary line
must run under and away from all electrical power wires
and terminals. The tube must never be in such a position
where it could accidentally touch the electrical power
terminals.
409
13. Carefully bend the capillary bulb and tube toward bulb holder on
heating elements.
14. Slip capillary bulb into bulb holder located on heating elements.
Pull excess capillary line from pot and tighten nut into frypot wall.

15. With excess capillary line pulled out, tighten smaller nut.
NOTE
Tighten nut to snug only. Too tight will damage
capillary line.
16. Replace front panel.
17. Refill with shortening.
NOTE
Heating elements are available for 208 and 480 voltage.
Check the data plate to determine the correct voltage.
If the shortening's temperature recovery is very slow or at a
slower rate than required, this may indicate defective heating
element(s). An ohmmeter will quickly indicate if the elements are
shorted or open.
1. Remove electrical power supplied to unit.
Place POWER switch in the OFF position and unplug the
power cord or open the wall circuit breaker.
2. Remove the control panel. Refer to Section 2-3.
3. Perform an ohm check on one element at a time, with wires
disconnected from element. If the resistance is not within
tolerance, replace the element.

Replacement
1. Drain the shortening from the frypot.
2. Remove the heating element wire from the terminals by removing
the nuts and washer. Label each so it can be replaced in the same
position on the new element.
3. Remove the retainer securing the silicone gasket.
4. Loosen the bolts on the four element spreaders.
5. Slide the element spreaders to the center of the heating element.
6. Remove the brass nuts (4) and washers (3) which secure the ends
of the elements through the frypot wall.
7. Remove the heating elements from the frypot as a group by lifting
the far end and sliding them up and out toward the rear of the
frypot.
8. Install new heating elements with new "0" rings (2) mounted on
terminal ends and spreaders loosely mounted in the center of the
heating elements.
9. Replace the heating elements, terminal end first, at approximately
450 angle, slipping the terminal ends through the front end of the
frypot.
10. Replace the brass nuts (4) and washers (3) on the heating element
terminals. Tighten the brass nuts to 30 foot pounds of torque.
11. Move the element spreader from the center of the element into a
position which will spread each element apart evenly on all four
sides and tighten.
12. Reconnect the wires to the appropriate terminal as labeled when
they were removed.
13. Replace the front control panel.
14. Connect the power cord to the wall receptacle or close wall
circuit breaker.
Heating elements should never be energized without shortening in frypot.
15. Replace the shortening in the frypot.

2-7. CONTACTORS
The following checks are performed with the wall circuit
breaker closed and the Power switch in the ON position.
Extreme caution should be taken. Make connections before
applying power, take reading, and Remove power before
removing meter leads.
1. With power applied, increase setpoint temperature setting allowing heat contactor to activate.
Test Points Results
Heat Contactor The voltage
from terminal 34 to 35 should read the
from terminal 35 to 36 same at each
from terminal 34 to 36 terminal.
Test Points Results
Primary Contactor It should
from terminal 27 to 28 correspond to
from terminal 28 to 29 the voltage
from terminal 27 to 29 rating stated on
the data plate.
If either contactor is defective, it must be replaced as follows:
1. Remove electrical power supplied to the fryer by unplugging
or opening the wall circuit breaker.
2. Remove only those wires directly connected to the contactor
being replaced. Label the wires.
3. Remove the two mounting screws on the base plate and
remove contactor.
4. Install the new contactor and tighten the two mounting
screws.

5. Connect the labeled wires to their respective positions.
6. Install the control panel.
7. Reconnect power to the fryer and test the fryer for proper
operation.
