✽
Since door switch sensing switch (A), (B) are a separate switch even if the door switch of the freezing room normally
operates, they may fail to sense door opening in the failure of switch at both ends of (A) and (B) or in failure of the L/wire.
✽
Lamp does at the cold storage room not turn on if the door switch of the cold storage room fails to sense the door open
switch (c ), (d) or the home bar switch.
