Why is food freezing in my Haier AFD631 Refrigerator compartment?

  Christine WilsonJul 30, 2025
  If food is freezing in the fridge storage compartment of your Haier Refrigerator, affix seal strip on the interface between the air door and the foam if the seal between them is not tight. If the sensor R1 is malfunctioning, replace it. If the main control panel is malfunctioning, replace it. If the connector of the air door is connected with reverse polarity, reconnect it correctly. If the air door is malfunctioning, replace it.

What to do if Haier Refrigerator is not defrosting?
- D
  Dennis GouldAug 8, 2025
  If your Haier Refrigerator is not defrosting, check if the temperature of the heating wire does not change, remove the fan cover plate to check if all the connectors are connected properly and test if there is 220V voltage output across the terminals of the heating wire. If the resistance of the defrosting fuse is infinite, the fuse is malfunctioning. If no malfunction is found in the above checks, please test the defrosting temperature sensor with a multimeter.

Why is the temperature too high in my Haier AFD631 fridge/freezer?

  rodriguezdeborahAug 12, 2025
  If the temperature in your Haier fridge or freezer is too high, it could be because the door is being opened too frequently or for too long, the temperature is set too high, the door isn't closing tightly, or the condenser is dirty. Try to open the door as infrequently as possible and reset the temperature. Also, make sure the refrigerator is on a level surface and there is no food or container interfering with the door.

  If you notice water, moisture, or frost in your Haier Refrigerator, it might be due to a hot and humid environment, the door not closing properly, or the door being opened too often or for extended periods. Ensure the refrigerator is level and that no food or containers are preventing the door from sealing correctly. Also, try to reduce how frequently you open the door.
