What does the F3 display on a car refrigerator mean?
2 Answers
When a car refrigerator displays the F3 error, it indicates that the current temperature cannot meet the required level, primarily due to excessively high ambient temperature. Below is the relevant information: 1. Definition of car refrigerator: A car refrigerator refers to a portable cooling device that can be carried in a vehicle. It has become a popular new-generation cooling and refrigeration appliance in the international market in recent years. 2. Classification of car refrigerators: There are mainly two types of car refrigerators available in the market. One is the semiconductor car refrigerator, which operates on the principle of electronic chip cooling. The other is the compressor car refrigerator, which uses traditional compressor technology found in conventional refrigerators. It can achieve lower cooling temperatures, ranging from -18°C to 10°C, with high cooling efficiency, capable of making ice and preserving freshness, but it is larger in size.
My RV fridge also showed this error code last week, it was so frustrating! I quickly checked the manual and found that F3 indicates a temperature sensor alarm. These compact fridges have a probe attached to the inner wall, which can shift position or get covered by frost over time. I tried cutting power for half an hour to reset the system, then used a hair dryer to warm the sensor area – and it actually worked! If you don’t have the manual, first try unplugging the power cord for ten minutes before reconnecting, and check if the rear ventilation vents are blocked by luggage. Remember: wait at least 5 minutes between compressor restarts – frequent on/off cycling can fry the circuit board.
