SECTION 1. TROUBLESHOOTING
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 indicates 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 avoided, could result in minor or moderate injury.
WARNING indicates a potentially hazardous situation which, if not avoided, could result in death or
serious injury.
DANGER INDICATES AN IMMINENTLY HAZARDOUS SITUATION WHICH, IF NOT AVOIDED, WILL RESULT IN DEATH OR SERIOUS
INJURY.

1-3. TROUBLESHOOTING
Problem Cause Correction
With the switch in the POWER
position, Fryer is completely
inoperative
Shortening will not heat but
lights are on
To isolate a malfunction, proceed as follows:
1. Clearly dene 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, injuries and/or property damage could result.
• Open circuit • Check to see if unit is plugged
in
• Check breaker or fuse at supply
box
• Check POWER switch per
Power Switch Section; replace
if defective
• Check voltage at wall
receptacle
• Check cord and plug
• Faulty contactor (elec.
model)
• Faulty temperature probe
• Faulty high limit

Have electrical supply, wiring, and elements checked
Because of the seriousness of this error code, turn the
POWER switch off and back on to cancel
This error code could be displayed even with the
POWER switch turned off. Unplug fryer or shut-off
the wall circuit breaker to disconnect electrical power
to fryer.
• The Min and Max amps limits are set as
percentages below and above the programmed
“Nominal Amps Reading” (Special Program
parameter SP-12). The Nominal, Min, and Max
amps limits can be viewed in Info Mode. (See the
E-25 error above for details.)
• Replace contacter
• Replace heating element
• Call electrician
1. Check that amp sensors are securely plugged into
the rear of the control board. If error still occurs,
proceed to step 2.
2. Check to see if the ohm value of each sensor is
within +/- 10% of 34 Ohms. If ohm value is not
within this range, proceed to step 3. If ohm value
is within range, proceed to step 4.
3. Replace amp sensors
