Troubleshooting and error codes
| Problem | Check | Explanation and Action |
|---|---|---|
| The refrigerator does not cool at all! | Has enough time passed after installation? | It takes 4 to 5 hours for the refrigerator to cool, and may take 24 hours in summer to fully cool. |
| Is the temperature setting set to "L"? Is the compartment set to Power Save Mode? | Set to "M" or "H", or set the versa compartment to "FRZ.H" or to the setting of your liking. Cancel Power Save Mode. | |
| Is the flow of cold air being blocked? Are the doors being opened frequently, or left ajar? Is food blocking them? | Make space between foods and remove any food that is sticking out of shelves or touching the ceiling of the drawers. Avoid opening and shutting the door for a while. | |
| Food freezes in the refrigerator and vegetable compartments | Is heat discharging being blocked? Check if there is no gap around the refrigerator and the refrigerator is exposed to direct sunlight. | Check that there is enough space around the refrigerator and that it is properly installed. |
| Is the temperature on the operation panel set to "H"? Have you placed easily frozen food containing a considerable amount of moisture in the compartment? | Set the temperature to "M". Also, the temperature with each setting may temporarily decrease. Place drinks and food containing a lot of water, such as tofu, vegetables and fruits, at the front of the shelf or in a door pocket. | |
| Is the surrounding temperature 5°C or less? | Cold air may escape and water may freeze. Freezing is less likely when the temperature settings are set to "L". | |
| Food in the lower case freezes | Is the surrounding temperature 5°C or less? Is the refrigerator compartment's temperature set to "H"? | Set the temperature of the lower case (when Supercool Chilling is set) to "L". Set the temperature of the refrigerator compartment to "M" or "L", or set the temperature of the lower case (when Supercool Chilling is set) to "L". |
| Are you piling frozen food onto other food? | Food that touches frozen food may freeze. | |
| Food in the versa compartment melts | Has the Supercool Chilling been set? | Set the Supercool Chilling. |
| Food does not quickly freeze | When storing ice cream and frozen foods, did you set the refrigerator to "FRZ.H"? | "SOFT FRZ", "FRZ•L", and "FRZ•M" are higher temperature settings. Set to "FRZ•H". |
| Soft-Freezing freezes food too hard | Is the versa compartment set to "FRZ"? | Set the versa compartment to "SOFT FRZ". |
| Does the food contain a lot of moisture? | Foods containing a considerable amount of moisture may freeze too hard. We recommend leaving the food for about 5 to 15 minutes, placing the other hand on the back of a knife, and cutting the food by pushing on it. Also, use the setting "SOFT FRZ L". | |
| Is food freezing the same way as with "Freezing"? | Food appears to freeze in the same way as with "Freezing". | |
| Cannot make ice / Water in the tank stays at the same level | Has enough time passed after installation? | It takes 4 to 5 hours for the refrigerator to cool, and 24 hours or more in summer to make ice. |
| Has food, the ice server, or another object been left in the ice storage box? Also, has the ice been leveled? | Remove food or other objects from the ice storage box. The ice storage box is judged to be full of ice. Also, spread the ice out flat all the way to the front. | |
| Is the ice making setting for the ice making compartment set to "ICE STOP"? | Set the ice making compartment's setting to ICE. | |
| Ice is small or joined together | Has the water supply pipe and water tank installed to the refrigerator without any gaps? Additionally, is the tank pipe installed to the water tank without any internal gaps? | Check the installation around the water tank. If there are gaps, the cold air may escape and water may freeze. |
