The lamp is blown.
F/R-H/B Door S/W is
good.
Lamp Control Relay
on PCB is good.
1. When replacing the Freezer Lamp, be sure to turn off the power to prevent electric shock.
2. Take care when replacing the incandescent lamp to prevent skin burn.
Caution
When the F-Door is open, its Door S/W will be open. And then 5V is to be applied to MICOM, signalling the Door Open.
After that, when 5V is input for more than 2 minutes, it will send out Door Open alarm for 10 seconds at an interval of 1
minute. (it's the same for the R-Door and the R/F-H/B Door.) So, when the Door S/W is defective, it will send "Ding
Dong" sound at an interval of 1 minute with the doors closed. In this case it needs repairing.
Note
The Room Lamp Relay
switches on & off when the
door gets opened and closed.
When the lamp does not light
up, check the relay operation
with its switching sounds by
opening & closing the door.
Note
When the lamp is controlled with Relay
(Refer to the specifications below).
