What to do if the freezer is humming

The freezer buzzes for a variety of reasons. Some of them can be caused by external factors, and some may indicate malfunctions. If the unit is installed against a wall or other device, vibrations in the engine generate vibration which causes the hum. The newly bought freezer may hum for the first five to seven days until it enters operating mode.

Also, the cause of the hum can be voltage drops in the mains or setting the thermostat to maximum. The most unpleasant situation why the freezer buzzes is a motor malfunction, which our Toronto appliance repair specialists can identify and eliminate.

The reasons causing the hum of the refrigerator

If your freezer suddenly buzzes, it could happen due to the following factors:

  • The unit is too close to a wall or kitchen cabinet causing the motor vibration. As a result of this vibration, the elements that are nearby are buzzing.
  • Constant power surges in the household power supply (in addition to clicks, there may be a hum).
  • Compressor malfunction. As a rule, a short circuit of the windings. To fix it the use of professional fridge repair services in Toronto is required.
  • The freezer thermostat is set to the maximum. For this reason, the compressor is overloaded working at the limit of its capability and producing a hum.
  • You have just purchased a freezing unit and it is now going into working mode. Typically, this period lasts 5-7 days.

If the freezer shakes and twitches you don’t need to panic right away. However, you still need to pay attention to this problem. Shaking can be caused by the following factors:

  • Metal knocking when turning the engine on/off. The reason may the fasteners that have become loose.
  • Incorrect installation of freezing equipment. The appliance is not on the level. It is especially important to pay attention to the correct installation if your floor is too uneven with large differences in height.
  • After purchasing the new freezer you forgot to remove the shipping screws from the device. Check this moment and if the shipping screws are still present, remove them immediately.
  • Worn or loose compressor shock absorbers. This is the reason why strong vibration from a running engine occurs.

If you’ve listened to your unit and heard that the device squeaks or makes clattering sounds, the reason may be the following:

  • You have not defrosted the freezer for too long. That has created a lot of ice on the sides of the chamber. This ice touches the fan blades of the No Frost system creating a characteristic crackling.
  • Some internal components and parts of the device rub against each other due to improper installation of the freezer unit creating a grinding noise.
  • Compressor creaks. This indicates that this part of the device is very worn out and will soon need to be replaced.
  • The squeak can be made by the walls of the case (especially if the case is made of plastic).

Sometimes, in addition to clicks and knocks, owners of freezers notice that their appliance begins to hiss. Typically this happens due to dirt getting between the blades of the No Frost system fan. To get rid of this unusual noise, just wash the freezer.

Sounds reminiscent of gurgling and hissing may be caused by the movement of a refrigerant. This is normal and there is nothing wrong with that. But if suddenly your fridge stops running, perhaps a refrigerant leak is the reason.
