Troubleshooting

Cabinet

The following ‘Troubleshooting’ guide should be used as a supplement to standard refrigeration
fault finding principles.

Complaint

Possible Cause

Repair

1. Cabinet warm,

product warm,
possible ‘HI’ alarm
activation

• External drafts, possibly from air-

conditioning, door ways or ventilation

fans. External drafts must be less than 0.2

m/s. Note: 0.2 m/s is not noticable by

touch. Generally, any noticable draft is too

much. Some drafts may be intermittent,

such as when air-conditioning cycles on

and off.

• Confirm visually any potential

airflow draft outlets. It may be

necessary to redirect ventilation

fans or relocate the cabinet.

• Cabinet loaded with very little stock or

unusual shelf position.

• Controller setpoint may require

change. Note: that an unloaded

cabinet generally operates warmer.

• Blocked or restricted condenser coil.

• Clean condenser coil (see page 57).

• Visually check condenser for

possible restriction. Remove

condensate tray and clean. If bad,

refrigeration unit removal may be

necessary.

2. Cabinet not

operating

• Loss of power supply.

• Check mains power supply and

cabinet isolation switch.

3. Compressor not

operating
- controller displays
‘HI’ alarm

• Faulty component.

• Repair or replace control.

• Blocked or restricted condenser coil.

• Clean condenser coil (see page 57).

• Visually check condenser for

possible restriction. Remove

condensate tray and clean. If bad,

refrigeration unit removal may be

necessary.

4. Cabinet lights not

operating

• Blown fuse.

• Replace blown fuse.

• Faulty night blind light switch.

• Check switch.

• Loose electrical connections.

• Check all light connections.

• ENSTO plug not plugged into controller

box socket.

• Check plug.

• Controller alarm

• Determine cause and eliminate (see

page 10).

• Failed light power supply

• Replace light power supply.

5. Unit defrosting

excessively

• Unit will demand defrost regularly if the

evaporator temperature is over cold due

to being short of refrigerant or starved

evaporator.

• Check evaporator refrigerant flow

and make suitable repairs.

6. Product warm

- no alarm

• Blocked or restricted honeycomb air grille. • Remove and clean, or replace

honeycomb.

• One evaporator fan not operating or

incorrect rotation.

• Check power supply plug is fully

engaged into motor. Repair or

replace evaporator fan motor.

• Unit defrosting excessively.

• See number 5 above.

• Restricted return air grille.

• Remove restriction.
