  Troubleshooting

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 noticeable by 

touch. Generally, any noticeable 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 40). 

• 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 40). 

• 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.

• Loose electrical connections.

• Check all light connections.

• Tyco plug not plugged into controller box 

socket.

• Check plug.

• Controller alarm

• Determine cause and eliminate (see 

page 9).

• 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.
