Poor cooling and freezing up - Refrigerators

Hi Mags.
Clogged coils can cause poor cooling. Check to make sure nothing is stuck in the condenser fan and that it spins freely (models with coils on the back won't have a fan). To do this, unplug the fridge and pull it out. ... Plug in the fridge and make sure the fan runs when the compressor is running.

Not sure what noise you are referring to but if you can here the refrigerant..."hissing " or maybe "bubbling" it is likely low. Leaking somewhere, likely freezing up. Good Luck!!

You either have a Freon leak or poor air flow

Samsung refrigerators have the condenser coil fan motor that goes bad. Check if this is the problem. This could cause a poor freezing isssue.

Few things cause this. Poor or no airflow inside the furnace, dirty filters, poor filter placement that will cause your indoor cooling coil to plug with dirt, or low freon pressure.

Refrigerator or Freezer not Cooling or Getting Cold

check for a blockage. There is only one cooling section, divided by airflow for freezer / fridge.
Perhaps something sticky is in the vents, or the freezer section has poor airflow, resulting in ice formation.
Unplug the unit for several hours, clean out vents, and make sure freezer section has good airflow from the vents.

unplug the refrigerator, remove the back panel inside the freezer, plug it back on, see if the freezer fan is working, if not replace it. if fan is working but there's a block of ice on the evaporator, replace the defrost timer located next to the thermostat, the defrost thermostat located on the evaporator and test the defrost heater element with a multi-meter.

Your filter is plugged, or the refrigerant is low, or it is getting too cold outside overnight (less than 60degf)

1) The two most common causes of insufficient air flow are dirty filters and under sized ducts. A dirty filter limits air flow which in turn allows the cooling coil’s temperature to drop below freezing. Replacing the filter, monthly, usually alleviates this problem. Under sized ducts will also cause the system to freeze
Because it also limits the amount of air flowing over the cooling coil. This results in lowering the coil temperature and allowing the humidity in the air to collect on the coil and freeze.
2)Refrigerant charge. The refrigerant system teeters on a delicate balance. If the system is not charged correctly, the system will not function properly. This malfunction may result in the poor cooling output and/or freezing up. Only a qualified, certified service technician can properly test and charge a refrigerant system.
3) Outdoor temperature. If night time temperatures are too low, the system will not operate properly, and freeze up may occur. The outdoor unit does not function well in temperatures below 60 degrees F. A special “ambient temperature” control must be installed to allow the unit to run properly in cool temperatures, or you may open your windows and save energy.

The timer motor can die or the timer can simply hang up in the defrost mode. The heater can blow out just like an ordinary light bulb over time. The terminator will actually swell up and fail also. MORE...
