Freezer coils freezing - Refrigerators

The red light that comes on and the freezer not freezing could indicate a few possible issues: Temperature setting: Check to make sure that the temperature setting in the freezer is set correctly. If the temperature is set too high, the freezer may not freeze properly. Thermostat: The thermostat may be malfunctioning, which can cause the freezer to stop freezing. You may need to have it replaced. Evaporator fan: If the evaporator fan is not working, it can cause the freezer to stop freezing. You can check to see if the fan is running by listening for it or feeling for air flow in the freezer. If it's not running, it may need to be replaced. Condenser coils: Dirty or clogged condenser coils can cause the freezer to stop freezing. You can clean the coils with a vacuum or brush. If you've tried all of these troubleshooting steps and the problem persists, it may be best to contact a professional technician to diagnose and repair the issue.

Condenser Coils clean or Evaporator Coils clean?

An iced up evaporator coil can cause a freezer not to freeze goods. That is caused by a failed defrost timer or a failed defrost heater.

Or it needs gas topping up.

Sounds like the air circulation fan isn't running. The air must be circulating to freeze. First tip off is the coils are iced up, second, unit isn't freezing. Find the fan inside the freezer and check that it will turn and it's not stuck. Sometimes a little 3 n 1 oil on the bearing shaft into the motor is all it takes to get it running again.

Check for ice / frosting inside the freezer .... If present you probably have a defrost problem.... This causes the freezer coil to ice up and block the air flow ... the causes could be a bad defrost heater , defrost timer, defrost sensors, or control board. Also make sure that the condenser coil is clean. remove ALL dust with a vacuum and a coil brush .the coil is located either on the bottom or on the back side of the unit...

Hi,

coil freezing is a sign of under charged system. Contact aized service center for recharging of refrigerant.

I hope this helps.

Turn off the refrigerator.Remove the freezer shelves/bins and rear panel.
Take a hair dyer and thaw the ice completely. The defrost heater will be across the bottom of the freezer coil. The defrost thermostat will be attached to a refrigerant coil at the top of the freezer coil.It is about the size of a quarter and 1/2 inch thick.There will be wires from top to bottom on the sides of the coil.

In the freezer coil is a defrost heater coil, and a defrost thermostat. You have to expose the freezer coil to find them. If your local dealer can't get parts, I get mine from Repairclinic.com.

The freezer door not closing properly would caused the freezer to freeze up
