Q: Why does my OK OFK 412 D refrigerator freeze food at thermostat level 1?

Level 1 of the thermostat is actually the warmest setting (least cold) of the OK OFK 412 D. If your food is freezing despite this low setting, it indicates a malfunction or incorrect setting. Initial checks Check the thermostat - Level 1 should never cause freezing. The slider may be stuck or misaligned. Try turning it slightly to ensure it moves correctly. Test at a lower level - If available, set the thermostat to position 0 (full stop) for a few minutes, then return it to level 1 to reset the system. Check the door seal - A poorly closed door or a defective seal can cause extreme temperature variations. Ensure the door closes tightly. Check the ambient temperature - The refrigerator operates correctly only between 16°C and 38°C. A kitchen that is too cold can amplify cooling. Recommended setting The manual recommends using level 4 for normal operation. Start with this setting and monitor the temperature for 24 hours before adjusting. If freezing persists at level 1 or level 0, the thermostat is likely defective and needs repair.

Q: Why is the refrigerator not cooling?

First of all, check the following points: Initial running time: After plugging in the appliance, wait 2 to 3 hours before loading food. If you have just transported it, wait 12 hours after unpacking before plugging it in. Ambient temperature: The OK OFK 412 D refrigerator operates correctly only if the room temperature is between 16°C and 38°C . If your kitchen or garage is too cold or too hot, the appliance will not cool properly. Thermostat setting: Check that the mechanical thermostat (with levels 1 to 7) is not set too low. The levels simply indicate the relative degree of coldness, and level 4 is generally recommended for optimal operation. Door closure: Ensure that the door is properly closed and that the seal is not damaged. After 60 seconds with the door open, an alarm will sound. Air circulation: Food should not come into contact with the back wall, as this would block the circulation of cold air. Leave a free space. If after checking all these elements the refrigerator still does not cool properly, contact the manufacturer's technical service.
