  If your Hisense Refrigerator isn't working correctly, first ensure the power cord is properly plugged into the outlet. Then, check the fuse or circuit of your power supply, and replace if necessary. If the ambient temperature is too low, try setting the chamber temperature to a colder level. Also, note that it's normal for the freezer not to operate during the automatic defrost cycle, or shortly after being switched on, to protect the compressor.

  If the temperature inside your Hisense Refrigerator is too warm, it might be because the doors were left open too long or too frequently. Another reason might be that the doors are being kept open by some obstacle. Also, check that the appliance has sufficient clearance at the sides, back, and top.

  Madison NorrisAug 21, 2025
  Unusual noises from your Hisense Refrigerator can be quite normal, such as compressor running noises, air movement noise from the fan, gurgling sounds similar to water boiling, popping during defrosting, or clicking before the compressor starts. However, other noises might be due to the cabinet not being level, the back of the appliance touching the wall, or bottles/containers knocking against each other. Check these potential issues.
