7-2. Main control PCB connections
There are 4 connectors on the main control panel of CFE/AFL/AFD refrigerators.
CN1 is the connector for the sensors and the door switch. Its pins from the left to right are:
1: GND
2: +12V
3: Door switch signal. When the door is opened, GND and the signal wires are switch to conduction.
When the door is open, the wires are disconnected;
4-6: Null
7-8: Connected to the fridge storage temperature sensor. We can test the sensor with these two wires.
Its resistance in normal operation is between 6.35 and 3.88k (correspond to 0℃~10). The
resistance at normal temperature is between 2.45 and 1.58k (correspond to 20℃~30);
7-9: Connected to defrosting temperature sensor. We can test the sensor with these two wires. Its
resistance in normal operation is between 10.9 and 25.19k (correspond to -10℃~-25). The
resistance at normal temperature is between 2.49 and 1.61k (correspond to 20℃~30);
10-11: Connected to the freezer storage temperature sensor. Resistance test is the same as the
defrosting temperature sensor;
12: Null
CN2
is the connector for the LED lamps and display panel:
1: GND
2: +5V
3: Com
4: Com
5-6: Null
7: +12V
8: GND
CN3
is the connector for the power cables
1: Zero line
2: Live line
3: Compressor (between it and the zero line)
4: Null
5: Heating tube for defrosting. The resistance between it and the zero is 345±10%
6: Null
CN4
is the connector for the air door and fan:
1: Feedback signal from the fan
2: GND of the fan
3: +12V of the fan
4: fan +12V
5-6: Null
7-9: Motor of the refrigeration air door
