Troubleshooting and error codes

Malfunction Check/Remedy
The chamber is not cooled at all
  • The circuit breaker of power source is active.
  • The voltage is too low (In this case, call an electrician).
  • The power is not supplied.
  • The breaker is free.
  • The large amount of articles (load) is stored in the chamber at one time.
The cooling is poor
  • The ambient temperature is too high.
  • The latch of inner door is not closed completely. The outer door is not closed firmly. (The frost or ice between the cabinet and door gasket possibly prevents door seal.)
  • The air intake vent is blocked.
  • The condenser filter is clogged. Always clean the filter when the filter check lamp is lit.
  • The door is not shut tightly.
  • The inner door is not installed correctly.
  • The set temperature in the control panel is not set properly.
  • The grille is blocked out.
  • The freezer is in the direct sunlight.
  • There is any heating source near the freezer.
  • A rubber cap and insulation are not set correctly on the access port.
  • You put too many unfrozen articles into the chamber.
Alarm test key cannot actuate the alarm
  • The alarm is activated only when the battery switch is ON.
  • When only the buzzer or only the alarm is actuated by the alarm test key, the unactuated part is out of order, and must be replaced.
