Question about LG LRBN20510WW Bottom Freezer Refrigerator

1 Answer

Where do you get replacement motor for fan?

I have a similar situation as a previously posed question. My freezer is freezing but the refrigerator is not cooling. Following the instructions, in that posting, I found that the 'fan' behind the 'wall' is not spinning. The response suggested replacing it, where do you get the replacement motor? In that same posted, the author said that the thermostat might also be to blame, where can a replacement for that unit be found? Thanks in advance! Allan

    I will give that a shot, but when the refrigerator was cooling you could hear the fan with the door shut, now you cannot. I assumed that meant the motor was gone, so in the meantime I order the part from LG ($10 with shipping). How do I 'power it direct from the mains' to test the installed motor?

    Thanks for the super fast response!

    no ice around fan, it spins freely. How can I check to see if door switch is working? So you don't think a faulty thermostat is likely?

    Sorry about delay, I work nights, it was easier to find my multimeter in the day time. Check motor, it has a good signal. I assume this means the motor works and that my problem is now somewhere else? The part I ordered did arrive but apparently I spent so much time describing the 'fan' that I ordered IT (the fan), and not the motor. I 'checked' switch light turns off when you push it.

    Thanks again for quick responses.

    how would I go about wiring the fan in parallel with the compressor? How can I check the fan stat? How can I check if there is a system fault?

    Thanks again!

  • Allan Ebalo Apr 11, 2007

    I got a copy of the pdf file with a parts list for my refrigerator. The 'stat' you were refering to, would it be the defrost control assembly?

    thanks again for all your help.

  • Allan Ebalo Apr 16, 2007

    Swapped out 'stat'. How long will it take before it functions in the refrigerator? And since I had the old one in hand I checked with my multimeter. It 'seems' continuous(?). What are the other possible problem sites?

    Thanks again!

  • Allan Ebalo Apr 16, 2007

    Bad news. Swapped out 'stat' waited your recommended 15mins, and more (ice started to build up on it ) and nothing. Fan motor has not yet arrived will swap that out and see. I talked to a gentleman (in RL) who has worked on lgs and he recommended swapping out the control board (stupid expensive!). Earlier you suggested a faulty door switch. IF the light turns off it works right? Getting on towards 3weeks with no refrigerator things are starting to get ugly here, and I'm not talking about JUST the refrigerator.

    Thanks soooo much!

Hesitate a little. the fact that the fan not spinning does not mean it is faulty. check continuity across the fan or if you can do so safely, power it direct from mains. remember a lot of these fans are unpowered when the door is open as well

    fact that you cannot hear fan with door shut can mean:
    ice build-up round fan jamming it - most common
    fan faulty
    door switch faulty

    to power up direct from mains - check fan is mains voltage. it should have a little lable on it giving voltage. literally just disconnect and run a lead from a mains supply and see if it runs. in practice these fans are reliable and think problem probably lies elsewhere

  • douglas smith Apr 02, 2007

    before you go any further, you need to check that the fan is in fact faulty. a simple continuity check will tell you that or power up direct as previously suggested. or if the new part has arrived, just substitute and see what happens.

  • douglas smith Apr 04, 2007

    a possibility is that there may be a fan stat mounted on the evaporator - fan doesnt turn on till evap is cold. this stat may be faulty. alternatively, if there is a system fault, the evaporator may not be getting cold enough operate the stat.

    a pal of mine used to just wire the fan in parralel with the compressor to do a cheap and cheerful repair

    never timed it but should work within about 15 mins.

Refrigerator part not keeping cold- freezer freezing. I unplugged it . Cleaned the freezer and thawed it out. It seems ok but the refrigerator part is not cold.

There is a fan that delivers cold air from freezer to the fridge section. if freezer is working fine, and fridge part is not cooling replace the fan motor/fan

Why doesn't it freeze or make ice?

The freezer fan motor is running slow, replace this part, this is a common fault


GR-349SQF won't freeze


Compressor is one reason why your freezer may not get cold. The compressor which is usually found at the back of the freezer helps to pump out gas/ cold air and the fan circulates this cold air in the freezer. If this compressor is knocked/defective, the freezer won't cool. Also, gas in the compressor sometimes get's finished and needs to be refilled. So, the compressor needs to be checked in a situation like this.

Fan problem is one of the most common reasons for the freezer to start failing, this is called "frost free failure." Ice can build up on the evaporator coils over time, and this ice builds up until it starts blocking the fan. The fan is responsible for circulating cold air throughout the freezer, so if it is blocked the freezer will not be able to freeze any food. You can usually check this by removing an access panel in the back of the freezer to inspect the coils. If ice is built up on the coils, a hairdryer can assist in defrosting them.

It's also possible that the fan is not running at all. If the fan is burned out or the motor isn't running, cold air can't circulate through the freezer and everything will melt. You can normally hear the fan motor switch on and off from time to time. Listen for it and if you can't hear it coming on for an extended period of time, the motor may need repair or replacement. The wires connecting to the fan may be the problem, preventing the fan from receiving electricity.

Several other problems could be keeping your freezer from freezing:

There could be leaks in one or several of the hoses in the refrigerator, which results in the cold air being lost instead of circulating properly throughout the fridge and freezer.

If you have the freezer so full that the cold air can't circulate, your food will thaw even though the freezer isn't malfunctioning. Always leave some space open in the freezer and try to not store food right up against the cooling vents.

The thermostat might have shorted out, which means the freezer can't accurately determine how cold it is. If this is the case, the refrigerator would probably not be working, either.

If your defrost drain becomes clogged, the water in the line will just refreeze over and over again, which could damage the lines as well as the fan. Always check the drain and make sure no sludge is building up in it if you have a self-defrosting refrigerator.

Always try to keep the freezer door closed for long periods of time. The more the door is opened, the more warm air is let in and cold air is released. If the door is opened frequently, the freezer could be warming faster.

I hope the above helps.....

For further assistance, please let me know.


Fridge doesn't cool.

Hello, would you happen to have the make and model number of your refrigerator? In a refrigerator the freezer side of the refrigerator is the only side that produces the cold. If your refrigerator side is not cool but your freezer side is one of the first things that you would check would be to open the freezer door and look along the rear wall of the freezer to see if you notice any frost or ice build up on the rear wall. If you did this is termed as a defrost issue and message me back that you do have this situation and I will instruct you how to diagnose this to correct this situation. If you had no ice/frost build up on the rear wall you would next assure that the evaporator fan is blowing air inside of your freezer. If you felt no air blowing inside of the freezer you would then remove the rear wall on the inside rear of the freezer by unscrewing the 1/4" screws. This would give you access to the evaporator coil and above the coil would be the evaporator fan motor. I will await your reply to your finds as to if there is any ice/ frost and if the evaporator fan is blowing air inside of the freezer before further diagnosing.
Thank you

F&P fridge not cooling and the freezer is icing up model E442B it isn't flashing codes

Check fan by removing and connecting to a 12v dc source. Ensure 12v is available at the plug situated on the fan baffle plate. Allow ice to thaw on lower condenser before replacing fan (replacment fan if necessary) Fan must recirculate air to freeze contents of freezer.

Freezer fan does not come on . Thought that replacing the DC motor would "fix" the problem. It did not. The compressor works as the freezer gets cold, but the fan never works so the refrigerator side does...

You have a bad main control board . The board in back of the refrigerator , behind an 8"X10" panel . Keep your old motor to play with . A small 9 volt battery will run it . I may have found 1 bad dc freezer fan motor in all the time i've worked on the new style G E refrig.

Kenmore Refrigerator: Freezer not freezing

a blocked condenser can cause a warm up situation,and after youve done this you have to wait 24 hours before making desision on out come.but other possiables are condenser fan motor slow,its fan blade dirty.defrost problem,frost on back frezer panel can be a sign of issue.evap fan moving air slow[inside fan]run time,is it running enough[thermostat controls that]if all those ok could be restriction in sealed system,that where the freon curcit.if moisture,or particles they can get caught in the cap tube[small tube to create persure so then freon expans to a gas]that should give you a few ideas.God bless ,tom
