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.

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 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.
