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.

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.

2-14. FILTERING SYSTEM The filtering system consists of the filter valve, motor and filter pump

assembly, filter screen assembly, and tubing.

Shortening with temperature in excess of 200 OF flows
through this filter rinse hose. Heat causes the rubber hose
to age and deteriorate. The hose and fittings should be
checked daily. If aging or discoloration is seen the hose
should not be used. Severe burns may result if this rinse
hose assembly leaks or ruptures.

1. Close the filter valve.

2. Turn the pump switch to the OFF position.

3. Detach the hose BEING CAREFUL, AS THE HOSE AND
FITTINGS WILL BE HOT, USE A COLD WET CLOTH.

7. Replace the valve and reassemble in reverse order.

The two most common causes for a fryer's inability to pump shortening
is that the pump is clogged with breading or solid shortening has
cooled and solidified in the lines and pump. This then could cause the
thermal reset to kick the motor out and the reset button on the back of
the motor needs reset.

To avoid electrical shock or other injury before starting this
procedure move COOK/PUMP SWITCH to OFF position.
Disconnect main circuit breaker at the circuit breaker box
and unplug service cord from wall receptacle.
