Defrost problem on a LG Bottom Freezer Refrigerator

Frost building up on the inside back wall of the freezer. The fan is now making noise as it works to spin against the frost build up.

I had the same trouble. I found out if you have the digital display of temperature type of refrigerator adjust the freezer temperature to +5 degrees. The defrost systems uses a circuit board type. Not sure how it works. I took the back panel of and looked at the board. Did not see any manual defrost methods. I had to remove all the contents of the freezer and manually defrost. have not a problem since.

You have a problem in the automatic defrost circuit. I suppose you know that !
You may have to disconnect the power from your refrigerator and use hot water in a pot or a hair drier to melt the ice away. You'll have to remove the back cover of the freezer and clear the ice from there too. You most likely have an open defrost heater and/or defrost thermostat.
If you have a tech sheet which is normally stored near the compressor section, you can trace the circuits and find your problem. If you're not comfortable with this kind of work , you'll need to call a tech to check it out for you. If you don't do something soon you'll lose all the food in both your refrigerator and freezer sections.
I hope this helps you

Refrigerator does not freeze enough


Lets have a look at rear wall of freezer, is there frost building up? Usually in top freezers the cold air settles to bottom and you don't notice fresh food section until about a day. If frost is building open fresh food sections door and in control panel=> CLICK HERE see item 257 in photo? That is WR9X565 or 311082 Defrost Timer Just below that is the control panel cover and you should have a small plastic plug covering a hole just below the defrost timer. Pry plastic plug out and using a flathead screwdriver turn the defrost timer clockwise slowly. Once you hear the compressor and fans stop stop turning timer and about a minute later you should hear some crackling noise coming from freezer. Allow to stay like that for up to 30 minutes and timer should come out of defrost and compressor and fans should start again on their own. If this action caused defrost then replace the defrost timer. If that does not seem to cause defrost the we need to go to step two, unplug and place items in a cooler or alternate refrigerator and use a hair dryer to assist in melting the ice behind rear panel. Remove rear panel in back of freezer and see => Freezer Components item's 621 and WR51X10038 or 880036 Defrost Heater Assembly
You will need to remove rear panel and work with refrigerator unplugged from power. On this=> Page watch how to test your defrost element just beside a photo of the timer. Most times I replace the defrost thermostat while inside freezer wall but I will let you try this first and please respond and rate, Thanks, Sea Breeze

The fan is running in the freezer constantly and frost is building up on the walls of the inside of the freezer. The fan is making a loud buzzing noise.

Hello there
Please follow these steps first ok
It's noisy Noise can come from these areas: The inside of the freezer The outside back of the refrigerator The bottom of the refrigerator 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 it may make noise

Refrigerator was making a 'Thump'' noise every so often and just stopped working. Freezer is still working It's a kenmore elite 3 door bottom freezer refrigerator model number 76539


Unplugging for an hour won't allow it to defrost if that is what the problem is.

Look inside the freezer at the back wall. Look for heavy accumulations of ice building on the cooling coil, which is behind the back wall panel. You may have to look in the louvers or past where the evap fan is located.

Once we know if there is heavy frost or ice there, we'll have a better idea how to resolve. Is there any warranty on this refrigerator that you know of, besides the 5 year compressor warranty?

Freezer building up with frost


Sounds like the defrosting system has a faulty timer/board, faulty heating element or bad electrical connections to these components.

More info, let me know...

LG fridge/freezer rumbling/vibrating sound


Check your defrost components. The fan is hitting the frost buildup and will shut off when the door is opened so as to not circulate the warm air. The heater or the timer is not doing a proper defrost cycle.

Hi

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.”

Please revert for further assistance and Do accept the solution if found useful.

Thanks

Is your fan blowing in the freezer? Frost on the back wall of the freezer usually indicates a defrost problem... defrost themostate, heaters, take back panel off and check evap for frost build up and if your fan in working.
