Condenser fan making noise and sometimes makes a clicking noise coming from electrical board on back

needs new control board wr55x10942. condensing fan not running or running slow. it get to hot then the compressor relay cut off compressor to protect it once cooled down enough it starts back running.

. The next time the noise starts , open the freezer door and see if that is where the noises coming from . If yes , replace the circulation fan located in front of the evaporator assembly . If the noise is coming from the bottom of the unit and you can hear it clearly with the doors closed , more than likely it would be the condenser fan located next to and sometimes even mounted on the condenser assembly . If the unit has a static condenser , which will be indicated by the metal lines running up and down and all around the back of the unit itself , there is no condenser fan . The squealing noise you hear is a bad bearing in one of the motors . As the motor shaft spins , it actually wobbles within the bad bearing as too much clearance between the two exists .

Hi!!

I think the clicking noise behind the unit comes from the compressor bimetal thermal protection, which can be caused by the condenser fan not worikng (the small fan on the back bottom of the unit) and/or dirty/clogged condenser.(the coil in front of the fan)

Also check:

Temp. control knobs,

Small fan in freezer, it should start working after opening the freezer door for a couple of minutes. If it does not start, use a pen or pencil to turn the blades, if it kick in, replace motor.

Remove freezer back panel (where the little fan is) and check for iced evaporator coil, if so, unplug unit and use a heat gun or hair dryer to melt ice, make sure the air duct going to the fridge is clear.

Once this is done, restart unit

Keep me posted!! Rate this post!!!

Noise can come from these areas:
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.”

Main board is defective. Replace part # should be wr55x10552.

Some areas noise may come from:
Inside:
Whenever the refrigerator is cooling a circulating fan is operating to move air through the freezer and refrigerator. This fan can be found in one of several locations: For freezers positioned on top of the refrigerator the fan can be found on the back wall at the center of the freezer; If your freezer is on the bottom then the fan will be near the top on the back wall of the freezer; and if your freezer is on the side the fan will be on the back about 1/2 way up or near the top.
These fan tend to wear out over time and make a noise like a whistle or chirping sound. Open the freezer and press any switch. If the noise is louder with the door open the motor that operates the evaporator fan is likely the cause. This fan cannot be serviced in any way and must be replaced.
The back of the refrigerator:
The compressor, defrost timer, or the condenser fan motor may be the cause of noise from the back. The compressor is located near the bottom and is identified by it's small black case that appears to have no moving parts, but several colored wires coming out of it. If you find the compressor is what is making the noise then you will have to replace it in order to get the noise to stop, these aren't serviceable (and can be expensive). Near the back of the refrigerator you'll also find the condenser fan. Sometimes this fan gets clogged with debris and can make a lot of noise as a result. If this is the case then simply clean the blade with a soft bristled brush, you can usually get one of these brushes from a hardware store, or you can order it from us by calling our 800 number. If it doesn't need to be cleaned then the whole motor may need to be replaced.
The defrost timer is usually found behind the kick panel. The timer has an electric motor attached to it that may become noisy over time and will need to be replaced in order to get it to be quiet again.
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.”

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.

This unit, I believe is a piezo electric cooling/warming unit. It's possible that after or during your defrost, the control board was exposed to excess moisture... whether by condensation (sweating), evaporation or direct contact with the melted water. In this case, if you plugged the unit in before allowing sufficient dry time, it would have shorted your control board. Possibly allow the unit to dry (unplugged) for 24-48 hours and retry. If the same symptom occurs, replace the control board.
