About VIDEOCON refrigerator PCB BOARD
The PCB (Printed Circuit Board) in a Videocon refrigerator is the main electronic control unit that manages cooling, defrosting, and overall operation of the appliance.
Key Functions & Description:
- Main Control Unit (Brain):
Controls compressor operation, cooling cycles, and overall system performance.
- Temperature Control System:
Uses thermostat or sensors to maintain the desired temperature inside the fridge and freezer.
- Power Supply Section:
Converts incoming AC (220240V) into regulated DC voltage for electronic components.
- Compressor Control:
Switches compressor ON/OFF based on cooling requirement to maintain efficiency.
- Defrost Control (in frost-free models):
Automatically activates defrost heater to prevent ice buildup on evaporator coils.
- Sensor & Input Interface:
Receives signals from:
- Temperature sensor
- Defrost sensor
- Door switch
- Fan & Airflow Control (if applicable):
Controls evaporator fan for proper cooling distribution.
