㩵 Investigate the following cause when an alarm display lamp and

buzzer sound are working.

㩵 When use starts. Is temperature of the freezer chamber the value?

㩵 When it is using. Were not you taking the condition that opened the change of the

temperature command and a door for a long time? Did not you put the sample whose temperature was high in the freezer chamber? An alarm is canceled naturally when it is left in these cases.

㩵 The environmental temperature is too high. 㩵 The door is not shut tightly. 㩵 The inner lid is not installed correctly. 㩵 The set temperature in the controller is not set properly. 㩵 The grille is blocked out. 㩵 The filter is clogged.

(Clean a filter if an alarm display lamp has a flash and “Please check a condenser filter.” is indicated by you on the basic screen.)

㩵 The freezer is in the direct sunlight. 㩵 There is any heating source near the freezer. 㩵 A rubber cap and insulation for the access port are not set

correctly. 㩵 You put too many unfrozen articles into the freezer compartment.

㩵 When a stifling day lasts, or it sometimes dews in the exterior of the freezer by the installation features. When humidity is high, it touches the thing that water in the air is cold, and this is to the benefit that dew condensation is settled, and it is not a trouble. Take a butterbur with the cloth which dried when it dewed.
