1-1.INTRODUCTION
1-2. SAFETY
This section provides troubleshooting information in the
form of an easy to read table.
If a problem occurs during the rst operation of a new fryer,
recheck the Installation Section of the Operator’s Manual.
Before troubleshooting, always recheck the Operation
Section of the Operator’s Manual.
Where information is of particular importance or is safety
related, the words DANGER, WARNING, CAUTION, or
NOTE are used. Their usage is described on the next page:
SAFETY ALERT SYMBOL is used with DANGER,
WARNING or CAUTION which indicates a personal
injury type hazard.
NOTICE is used to highlight especially important
information.
CAUTION used without the safety alert symbol indi-
cates a potentially hazardous situation which, if not
avoided, may result in property damage.
CAUTION used with the safety alert symbol indicates
a potentially hazardous situation which, if not avoid-
ed, could result in minor or moderate injury.
WARNING indicates a potentially hazardous situ-
ation which, if not avoided, could result in death or
serious injury.
DANGER INDICATES AN IMMINENTLY HAZ-
ARDOUS SITUATION WHICH, IF NOT AVOID-
ED, WILL RESULT IN DEATH OR SERIOUS
INJURY.
SECTION 1. TROUBLESHOOTING

1-2March 2013
1-3.TROUBLESHOOTING To isolate a malfunction, proceed as follows:
1. Clearly dene the problem, or symptom and when it
occurs.
2. Locate the problem in the troubleshooting table.
3. Review all possible causes, then one at a time, work
through the list of corrections until the problem is solved.
If maintenance procedures are not followed correctly, inju-
ries and/or property damage could result.
Problem Cause Correction

lights are on
• Faulty contactor (elec.
model)
• Faulty temperature probe
• Faulty high limit
• Faulty drain switch
• Check contactor per Heating
Contactors Section
• Check temperature probe
per Temperature Probe
Replacement Section; “E-6”
• Check high limit per the

1-4. WARNINGSAND ERROR
MESSAGES
The controls monitor procedure problems and system failures
with warnings and error codes. The display shows the
warning or error code, and an alarm sounds.
Pressing cancels most warnings and pressing any
control button stops most error code alarms. But there are
some exceptions (see below). The display shows the error
until the situation is corrected.
WARNINGS
Display Cause Correction
