  If the compressor in your Haier Refrigerator isn't working, first, check if the refrigerator is plugged firmly into a working power outlet. If it is an automatic defrosting refrigerator, it may be in defrosting cycle, which is normal. Also, verify that the refrigerator is not in the OFF state. If it is, press the “Power” button for 3 seconds or more to restart the refrigerator, or turn the knob from OFF to a temperature selection position.

  If the fridge storage compartment in your Haier Refrigerator isn't working, first check the air door cable to ensure it's properly connected; if not, install it correctly. Also, the fan does not work while the refrigeration air door is open, so check if the door on-off behind the front decoration strip is installed properly and reinstall if necessary. Finally, make sure the fridge storage compartment is turned on manually.

Why does my Haier HFD647AS Refrigerator run so frequently or for long periods?
- S
  Sabrina TaylorAug 13, 2025
  Several factors can cause your Haier Refrigerator to run frequently or for extended periods. It's normal for it to run longer if the indoor or outdoor temperature is high, or if the automatic icemaker is operating. If the refrigerator has been powered off recently, it can take 8 to 12 hours to fully cool down. Also, ensure that the refrigerator door is closed tightly and not opened too frequently. Finally, check that the freezer temperature isn't set too low; adjust it higher and allow 24 hours for the temperature to stabilize.

  Heather Garcia DVMAug 19, 2025
  If you notice moisture accumulating on the inner walls of your Haier Refrigerator, it could be due to a hot and moist climate, which accelerates frost and moisture buildup. Ensure the refrigerator is level and that no food or containers are preventing the door from closing tightly. Also, avoid opening the door too frequently or leaving it open for extended periods.

Why does moisture accumulate on the outside of my Haier HFD647AS Refrigerator?
- M
  Mr. Logan RichardAug 26, 2025
  Moisture accumulation on the outside of your Haier Refrigerator or between the doors is normal in a damp climate, and it should decrease as the humidity drops. Ensure the refrigerator door is closing tightly and that the appliance is level, with no obstructions from food or containers.
