Grundig Duo-Cooling GKNG3691 User Manual

To adjust the temperature, locate the temperature control panel inside the refrigerator. Use the "+" and "-" buttons to set the desired temperature for both the fridge and freezer compartments.
First, ensure that the refrigerator is plugged in and that the circuit breaker has not tripped. Check that the doors are closing properly and that the vents inside are not blocked by food items. If the problem persists, consider cleaning the condenser coils or contacting customer support for further assistance.
The Grundig Duo-Cooling GKNG3691 features a frost-free system, so manual defrosting is not necessary. However, if you notice ice buildup, check the door seals and ensure the door is closing properly.
Unplug the refrigerator before cleaning. Use a soft cloth and a mild detergent to clean the interior and exterior surfaces. Avoid using abrasive cleaners or sharp objects. Clean the door seals with a damp cloth to ensure they maintain a good seal.
To replace the light bulb, first unplug the refrigerator. Locate the light cover inside the fridge, remove it, and then unscrew the bulb. Replace it with a new bulb of the same type and wattage, then reattach the cover and plug the refrigerator back in.
Check if the drain hole inside the fridge is blocked and clear any obstructions. Ensure that the refrigerator is level and that the door seals are intact. If the issue continues, inspect the water filter and connections if your model is equipped with an ice maker or water dispenser.
Ensure that the refrigerator is positioned away from heat sources such as ovens or direct sunlight. Keep the doors closed as much as possible and ensure a good seal on the door gaskets. Regularly clean the condenser coils to maintain efficient operation.
Locate the water filter compartment, typically inside the refrigerator or in the base grille. Turn the old filter counterclockwise to remove it and insert the new filter by turning it clockwise until it is secure. Run water through the dispenser for a few minutes to clear any air or contaminants.
Unusual noises may be due to the refrigerator not being level, or items inside vibrating against each other. Adjust the leveling feet and rearrange items to minimize noise. If the noise persists, it could be related to the compressor or fan, and you may need to contact customer service.
Common issues include uneven cooling or frost buildup. Ensure that the airflow vents are not blocked and that doors are sealing properly. For frost buildup, verify the door gaskets for damage and check the defrost system for any malfunctions.
