Controller display fault code problem
The controller continuously displays ER0 fault code Indicates that the temperature sensing head is short-circuited. At this time the compressor enters the timing working mode, it runs for 30 minutes and then stops for 30 minutes
Solution: Replace the temperature probe
The controller continuously displays the ER1 fault code Indicates that the module input undervoltage protection
Solution: When adapter power is being using, please replace the adapter
                   When the car power supply is being using, please adjust the voltage protection switch to mid-range or low-range. If the voltage protection switch still displays a fault code, it means that the battery voltage of the car is also seriously insufficient, and the battery needs to be charged or replaced
The controller continuously displays the ER2 fault code Indicates DC fan overcurrent protection
Solution: 1. Replace the DC fan
                 2. If RE2 is still displayed after replacing the fan, then replace the compressor module
The controller continuously displays the ER3 fault code Indicates abnormal compressor startup protection
Solution: 1. Check whether the external power supply (car power supply/adapter) is normal
                 2. Check whether the DC fan is running at the beginning of operation, if not, replace the fan
                 3. If the fan is running, replace the compressor
The controller continuously displays the ER4 fault code Indicates abnormal compressor speed protection
Solution: 1. Check whether the external power supply (car power supply/adapter) is normal
                 2. Check whether the DC fan is running at the beginning of operation, if not, replace the fan
                 3. If the fan is running, replace the compressor
The controller continuously displays the ER5 fault code Indicates module temperature abnormal protection
Solution: replace the compressor module first. If it is still faulty, you need to replace the compressor
The controller continuously displays the ER9 fault code Indicates that the temperature sensing head is open. At this time the compressor enters the timing working mode, it runs for 30 minutes and then stops for 30 minutes
Solution: Check whether the connection of the temperature probe terminal is loose. If it is loose, then reconnect the connector. If the connection is normal, you need to replace the temperature probe

Controller display fault code problem
The controller continuously displays LL fault code Indicates that the temperature sensing head is open. At this time the compressor enters the timing working mode, it runs for 30 minutes and then stops for 30 minutes
Solution: Check whether the connection of the temperature probe terminal is loose. If it is loose, then reconnect the connector. If the connection is normal, you need to replace the temperature probe
 The controller continuously displays HH fault code Indicates that the temperature sensing head is short-circuited. At this time the compressor enters the timing working mode, it runs for 30 minutes and then stops for 30 minutes Solution: Replace the temperature probe

Category Problems solution
Other common faults The compressor works normally but the temperature inside the box does not drop Main reason: the refrigerant leaks
Solution: Check the leakage point of the refrigeration pipeline by maintaining pressure, and perform repair welding and refill the refrigerant after finding the leakage point
The power indicator on the control board shows green, indicating that the compressor is working but the actual compressor is not working The main reason: the six-core connector on the control board is loose
Solution: Open the control board on the handle and reconnect the six-core connector
The temperature value displayed on the control panel is incomplete Main reason: part of the digital tube of the control board is damaged
Solution: Replace the control board
The compressor is working normally but the light in the box does not light up Main reason:The light panel is out of order
Solution: Replace the light board
Refrigerator is not working 1. Check whether the power supply is connected correctly (whether the plug is loose, positive and negative)
2. Check whether the power switch on the control board is turned on
3. Check if the fuse is blown
The noise refrigerator is abnormal 1. The car refrigerator is not stable
2. Touch a wall or other objects
3. The internal parts are loose or fall off
Condensation on the refrigerator surface When the ambient air humidity is greater than 75%, the product may be slightly condensed on the surface of the cabinet. The higher the humidity, the greater the probability of occurrence, which is a normal phenomenon
There is the sound of running water in the refrigerator This is the sound of refrigerant flowing, which is normal
Poor refrigerator cooling 1. Excessive storage of food makes the refrigerator crowded and cold air flow is not smooth
2. The door is not closed
3. Sunlight or a heat source nearby
4. Improper temperature setting
5. Put too much hot food
6. The door seal is damaged or deformed, and the seal is not tight
When the refrigerator reaches the set temperature and the compressor stops working, the temperature in the box will continue to drop After the compressor stops working, because the refrigerant pressure in each part of the refrigeration system pipeline has not reached equilibrium, so it continues to flow. And it will continue to evaporate and absorb heat. When the compressor stops for 3 minutes or longer, the temperature will not continue to decrease, which is normal
