What does F1 mean on a car refrigerator display?
2 Answers
The refrigerator displaying F1 indicates a fault with the refrigeration evaporator sensor (short circuit or open circuit). Solution for F1 display: Start the refrigerator after the car is ignited, use an adapter for power connection, and adjust the battery protection to medium or low level. Additional details are as follows: 1. Operating temperature of the refrigerator: Higher ambient temperatures result in shorter battery life. 2. Type and quantity of items stored in the refrigerator: More items require the refrigerator to consume more power to maintain the set temperature. 3. Frequency of opening and closing the door: More frequent door openings increase power consumption. 4. Capacity and charge state of the car battery: Larger battery capacity and higher charge levels result in longer usage time. 5. Set temperature of the refrigerator: Lower set temperatures consume more power. 6. Battery protection level setting of the refrigerator: Higher battery protection levels result in shorter usage time.
I often use a car fridge for camping when driving, and last time it showed F1, which was really annoying. Generally, the F1 code indicates a temperature sensor issue, commonly caused by dust buildup or loose wiring. Bumpy roads can easily lead to poor probe contact. Check if the ventilation ports at the back of the fridge are blocked, clean them, and then restart it. If that doesn’t work, check whether the cigarette lighter voltage is stable—too low or fluctuating voltage can also trigger F1. Don’t rush to replace parts; first, check the manual’s code table, as meanings vary by brand. Car fridges are handy but delicate; regular maintenance can prevent issues. If you encounter persistent errors, it’s best to stop using it and get it repaired to avoid food spoilage on the road. Before my next trip, I always remind myself to check it thoroughly.
