TROUBLE SHOOTING

If the unit malfunctions, check out the following before calling for service.

Malfunction

Check/Remedy

The chamber is not cooled

￿ The circuit breaker of power source is active.

at all

￿ 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 controller is not set properly.

 

￿ The freezer is in the direct sunlight.

 

￿ There is any heating source near the freezer.

 

￿ A rubber cap and insulation are not set correctly.

 

￿ You put too many unfrozen articles into the chamber.

Alarm test key cannot

￿ The alarm is activated only when the power switch is ON.

actuate the alarm

￿ 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.

Note:

 

If the malfunction is not eliminated after checking the above items, or the malfunction is not shown in the above table, contact Sanyo sales representative or agent.
