error code is displayed, and to silence this tone, press any of the
product buttons.
DISPLAY CAUSE PANEL BOARD CORRECTION
“E-4” Control board overheating Turn switch to OFF position, then turn
switch back to ON; if display still shows
“E-4”, the board is getting too hot; check for
signs of overheating behind the control
panel; once panel cools down the controls
should return to normal; if “E-4” persists,
have control panel replaced
“E-5” Shortening overheating Turn switch to OFF position, then back to
ON; if display shows “E-5”, the heating
circuits and temperature probe should be
checked; once the unit cools down, the
controls should return to normal; if “E-5”
persists, have control panel replaced
“E-6” Temperature probe failure Turn switch to OFF position, then back to
ON; if the display shows “E-6”, the tempera-
ture probe should be checked; once the
probe is repaired, or replaced, the controls
should return to normal; if “E-6” persists,
have control panel replaced
“E-41” Programming failure Turn switch to OFF position, then back to

2-1. INTRODUCTION This section provides checkout and replacement procedures for
the malfunction.
2-2. MAINTENANCE HINTS 1. A multimeter will help you check the electric components.
2. When the manual refers to the circuit being closed, the
multimeter should read zero unless otherwise noted.
3. When the manual refers to the circuit being open, the
Do not move the fryer with hot shortening in the frypot
splashing hot shortening.
4. Remove weights from frame to easily access rear of fryer.
2-3. PREVENTIVE To ensure a long life of fryers and their components, regular
MAINTENANCE maintenance should be performed. Refer to the chart below.
Frequency Action
Daily Clean deadweight assembly cap, weight,
See KFC’s Filtering of shortening
Monthly Check dilution box, clean as needed
(see section 2-25)
Monthly Clean the Nylatrons (see section 2-14)
Annually Clean blower wheel (see section 2-26)
(see section 2-32)
Annually Remove and clean safety relief valve
(see section 2-16)

2-4. HIGH TEMPERATURE
LIMIT CONTROL This high temperature control is a safety, manual reset control,
ing temperature exceeds 425°F (218°C), this switch opens and
shuts off the heat to the frypot. When the temperature of the
shortening drops to a safe operation limit (15-20 minutes),
manually reset by pressing the red reset button. The red reset
button is located under the control panel, in the front of the
fryer. Once reset, the frypot starts heating.
that its circuit is closed.
Checkout
The shortening temperature must be below 380°F
(193°C) to accurately perform this check.
1.Remove electrical power supplied to the fryer.
To avoid electrical shock or property damage, move the
power switch to OFF and disconnect main circuit
breaker, or unplug cord at wall receptacle.
2.Remove the control panel.
3.Remove the two nuts securing high limit bracket to the unit,
and pull the bracket from the unit.
4.Remove the two screws securing the high limit to bracket,
and remove the high limit from the bracket.
5.Remove the two electrical wires from the high temperature
limit control.
6.Manually reset the control, then check for continuity
the circuit is open, replace the control, then continue with
