The freezer will not defrost. The refrigerator makes as clicking noise as if it is calling the defrost unit, but it does not defrost.

Sounds like the compressor is trying to start. Shut it off overnight. Try re-starting. If it still clicks you'll need a service call.

Sorry to hear about your problem. Sounds like you have a defrost issue. Hence your unit is not defrosting. All of this apply's if your freezer side has ice on it. If not. you have other issues
Here is a list of some things that can go wrong.
1. Defective heat coil
2. Defective defrost timer
3. Defective defrost sensor
You should call a service company to resolve your issue.

Hi and welcome to FixYa, I am Kelly.
That strange noise your hearing is probably the fan blades of the evaporator fan striking ice build up on the evaportor coils. This symptom is typical of and automadefrosting problem.... or someone left the freezer door open for a very long period.
You can try doing a manual defrost by unplugging the unit and place a fan blowing into the freezer compartment / compartment making noise for about 2 hours. (makes a water mess) After 2 hours tend to the water mess and restart the unit. Most likely the noise you heard will be gone... for a few days. If you have an automatic defrost problem the noise will return in about 72 hours as the ice build up gets larger on the evaporator coils.

Depending on date of manufacture this unit can have either a manual defrost timer or an adaptive defrost control board that controls the automatic defrost. .

Thanks for choosing FixYa,

Hi,

Many times a freezer and/or refrigerator do not work right because of a dirty condenser coil...there are also many other things that can go wrong.

If you are hearing a clicking or buzzing then check out the last two tips.

If your refrigerator is running but warm, then...

Check out these tips that I wrote about that... it is a great place to start trouble shooting your unit...and something that you can do rather then calling a repair person to do a simple thing for you...

Refrigerator or Freezer not Cooling or Getting Cold

Hello, Self-defrosting refrigerators use a circulating fan to move air through the freezer and refrigerator compartment. This fan runs when ever the unit is cooling. The fan is located in the freezer, as follows:

• If the freezer is on top, the fan is on the back wall,near the top or bottom, in the center of the freezer.
• If the freezer is on the bottom, the fan is on the back wall, near the top of the freezer.
• If the freezer is on the left, the fan is on the back wall, half way up or near the top.

Overtime the fan may become noisy, usually making a chirping or squealing sound, though it may make a loud groaning noise instead.
To find out if the fan is causing the noise,just open the freezer door and push in any fan/light switches, if the noise is louder when the door is open, the evaporator fan motor is the cause. You can lubricate or repair this motor. You must replace it.
There are three components on the outside back of the refrigerator that may become noisy: the compressor, the condenser fan motor(if self-defrosting), or the defrost timer (if self-defrosting).
Thanks

Clicking could be a bad starter relay if the noise is coming from the back under the unit where the compressor is. check it here Check your compressor relay- http://www.acmehowto.com/howto/appliance/refrigerator/check/compressorrelay.php
The clicking could be coming from a fan, one of which is near the compressor under the unit and another is in the freezer behind the rear cover inside.
The defrost timer could be clicking. This sound would come from the fridge.

How to check everything

If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

check defrost timer, defrost heater, defrost thermostat.
You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

This might be a normal noise. when they switched to 134a refrigerant, they had to develop a new oil. This new oil comes over or circulates more easily then the old oil. The oil and refrigerant flow through a capillary tube under 180 psi to the evaporator where it expands. the noises from this process can sound like tapping, chirping, clicking, squealing or wheezing. A hot day, a dirty condenser or when the unit comes out of defrost will make the noises more noticeable.

IF the below mentioned information does not help, then contact a elextrical engineer worksman who can check the circuit board as it might also cause a short cicuit.

The inside of the freezer Self-defrosting refrigerators use a circulating fan to move the air through the freezer and refrigerator compartments. This fan runs whenever the unit is cooling. The fan is located in the freezer, as follows:

• If the freezer is on top, the fan is on the back wall, near the top or bottom, in the center of the freezer.
  
  
• If the freezer is on the bottom, the fan is on the back wall, near the top of the freezer.
  
  
• If the freezer is on the left, the fan is on the back wall, halfway up or near the top.
  
  

Over time, the fan may become noisy--usually making a chirping or squealing sound, though it may make a loud groaning noise instead.

To find out if the fan is causing the noise, just open the freezer door and push in any fan/light switches. If the noise is louder when the door is open, the evaporator fan motor is the cause. You can't lubricate or repair this motor. You must replace it.

The outside back of the refrigerator There are three components on the outside back of the refrigerator that may become noisy: the compressor, the condenser fan motor (if self-defrosting), or the defrost timer (if self-defrosting).

• The compressor is a football-sized case with no apparent moving parts. You can see it on the outside of the refrigerator at the back near the bottom. It is usually black and has black or copper-colored tubes and various colored wires attached to it. If the compressor is the device making noise, there is probably no repair that will reduce the noise. You will have to replace it--which can be quite costly.
  
  
• If the condenser fan is making noise, there may be a build-up of lint or other debris on the fan blade. The fan is located near the back of the machine, sometimes behind a thin panel. To clean it, first unplug the refrigerator, remove the thin panel, and use a soft bristle brush to clean it. If there is no lint build-up or debris on the blade, you will have to replace the motor.
  
  
• The defrost timer is often located at the bottom of the refrigerator, near the front and behind the kick plate. Occasionally the electric motor inside the timer may become noisy. The timer must be replaced to solve this problem.
  
  

The bottom of the refrigerator Noises detected at the bottom of the refrigerator almost always originate from the back of the refrigerator. However, sometimes the drain pan under the refrigerator will rattle. You may need to tape the pan in place to stop a rattle. Also see the “Outside back of the refrigerator.”

you may have defrost problem you will have to call them

IF IS NOT 5 YEARS OLD YET CALL A TECH ASAP THIS MODELS HAVE A COMPRESSOR THAT ARE FAMOUS FOR LOCKING UP AND THE ONLY FIX IS TO REPLACE IT BUT FIRST DISCONNECT AND REMOVE BACK COVER AND RIGHT BY THE COMPRESSOR THERE IS A SMALL BOX ATTACHED TO IT CALL A OVERLOAD REMOVE IT AND SHAKE IT IS IF RATTLES THEN JUST REPLACE THAT PART IF IT DOESNT RATTLE CALL A TECH
