DOOR OPEN WARNING of refrigerator compartment alarms for 10 seconds after 2 minutes when DOOR opened
initially. If the door is opened continuously it is alarmed for 10 seconds with a period of 10 seconds.
Because the penetration of moisture or vapor into DOOR S/W causes the junction SHORT of DOOR S/W, the
warning is alarmed continuously by judgement of MICOM which regards the DOOR as open state.In this case,
DOOR is regarded as continuously opened state after 10 minutes and the lamp of refrigerator is set to be OFF. So
if you open the DOOR, the lamp of refrigerator is maintained as OFF state.
If the moisture or vapor penetrates into the junction and corrodes it, the lamp of refrigerator is kept as OFF state and
DOOR OPEN warning does not work because the signal does not inputted to the MICOM.
