SECTION 1. TROUBLESHOOTING
1-1. INTRODUCTION
This section provides troubleshooting information in the form
of an easy-to-read table.
If a problem occurs during the first operation of a cabinet,
recheck the installation per the Installation Section of the Operator’s
Manual.
Before troubleshooting, always recheck the operation procedures in
the Operator’s Manual.
1-2. SAFETY Where information is of particular importance or is safety
related, the words NOTICE, CAUTION, or WARNING are
used. Their usage is described below .
SAFETY ALER T SYMBOL is used with DANGER,
W ARNING, or CAUTION which indicates a personal
injury type hazard.
NOTICE is used to highlight especially important
information.
1-3. TROUBLESHOOTING
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,
may result in minor or moderate injury.
W ARNING indicates a potentially hazardous situation
which, if not avoided, could result in death or serious
injury.
T o isolate a malfunction, proceed as follows:
1. Clearly define 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 problem is solved.
If maintenance procedures are not followed corr ectly,
injuries and/or property damage could result.

Green compressor indicator Compressor and condenser fan
light on and the compressor do not work:
not working, or working - Faulty contactor Check contactor and change if
sometimes necessary
- Faulty control board relay-no Replace control board

Compressor works, but condenser
fan does not:
- Faulty condenser fan Replace fan
Compressor and condenser fan
work together:
- Faulty protection component Check items and replace if
for the compressor (overload necessary

1-4. ALARM MESSAGES In the event of a system failure, the digital display will show an
alarm message. These messages are coded; “AL-1”, “AL-2”,
“AL-3”, “AL-5”, and “AL-6.” When an alarm occurs, the red
alarm LED will illuminate and a buzzer (optional) will sound. Press
the ALARM button to stop the buzzer .
The unit can operate on auto back-up if an alarm sounds for a
faulty probe. Must select the Timer Mode, and enter a time.
Display Cause Correction
“AL-1” Faulty air temperature Replace the probe; unit can operate on auto
probe back-up until a new probe is installed
“AL-2” Faulty evaporator probe Replace the probe; the de-icing cycle can operate at
50% of the setting in step 7 of the Programming Section
“AL-3” Faulty Frigiprobe Replace the probe; the Frigiprobe Mode will not
operate, but the unit will operate in the Timer Mode
“AL-5” Temperature too low Faulty control board - replace control board;
in the hold mode faulty contactor - replace contactor
“AL-6” T emperature too high in Faulty control board - replace control board;
the hold mode door opened too much - make sure door stays
closed as much as possible
