Common Reasons for Fan Only Working in Test Mode
If the fan in your LG refrigerator only works in test mode, there could be several reasons for this.
Here are Some of the most common reasons are:
Faulty Control Board
A faulty control board is one of the most common reasons for the fan only working in test mode.
The control board is responsible for controlling the fan’s operation, and if it is not functioning correctly, the fan may only work in test mode.
Defective Fan Motor
Another reason for the fan only working in test mode could be a defective fan motor. If the fan motor is not working correctly, it may only operate in test mode, and not during normal operation.
Faulty Thermistor
The thermistor is responsible for monitoring the temperature in the refrigerator and communicating the information to the control board.
If the thermistor is faulty, it may not be able to communicate the temperature information correctly, which can result in the fan only working in test mode.
Clogged Air Vents
If the air vents in your refrigerator are clogged with debris or ice, it can prevent the fan from operating correctly.
This can result in the fan only working in test mode, as it is unable to circulate air throughout the refrigerator.
Low Refrigerant Levels
Low refrigerant levels can also cause the fan to only work in test mode. If the refrigerant levels are low, it can cause the compressor to overwork, which can result in the fan only working in test mode.
