5-9. Door S/W Sensing Circuit
5. Circuit Descriptions
1) The terminals,
②
and
⑥
of the connector (CN30) are grounded, and DC5V (Vcc) is
supplied to the terminals,
⑤
and
⑥
through the resistors, R404 and R403 for the freezer
and the refrigerator door, respectively.
2) The micro-processor senses the door’s open and close based on engaged voltages,
“Low(0V)” and “High(5V),” respectively.
The door switch always should be checked when the evaporator fan is not
