I have an LG LDC 22720 refrigerator just out of warranty. Just recently the lights on the temp. control have been indicating a problem. The lighted numbers on the refrigerator temperature control side of the panel all go out and the "6" and "7" lights on the freezer control panel both come on. Unplugging the refrigerator for a while resets the lights, but lately the problem occurs more frequently, with this situation repeating again within minutes. When this happens the refrigerator stops cooling and the freezer works much less effectively. I have read that this configuration of lights on the control panel is an error code indicating a problem with the "thermal fuse". Where is this "thermal fuse" and how can I deal with the problem? Can you provide me with some illustrations showing me just what I am looking for? I have gotten into the panel at the back of the unit, on the bottom, to clean the condenser coils, (which didn't help with this problem). Are we talking about something in this same general area? The sealed unit seems to be working fine because when the lights on the control panel are in the normal configuration the unit cools beautifully. Any help would be appreciated.

The thermal fuse, sometimes called a "thermister" is a device that is usually located behind the rear panel in the freezer. It looks like a wire with a small thing on the end that is secured to the coils behind the rear panel. You will need to remove all the contents of the freezer and remove the rear panel in the freezer...You most likely are going to need to replace it, so getting a new one before you start taking everything apart will be a good idea..You'll need the model # of the fridge etc. Find an appliance parts dealer to acquire the new part which should be fairly inexpensive.. Search "refrigerator thermal fuse" on YouTube and you should find a few video's on what to do and what to look for..Good luck!

SOURCE: the refrigerator is not cooling properly , only

Hello,

If your refrigerator is not cooling, the problem could be any of the following, follow the steps below one after the other to fix the problem of your refrigerator not cooling.

First of all, the most simplest thing to do is to check the temperature. It might have happened that the temperature control may have been turned off unknowingly, which is the reason for the problem. So if that's the issue, just set the refrigerator at 37 degrees and you are all set.

Poor coiling leads to a heavy frost build up on the evaporator coils. A frost build up, specially on the ceiling of the freezer, is a sign of problem in the self defrosting system or damaged gaskets of the doors. Therefore, check if the refrigerator is facing such a problem and defrost the refrigerator. It would not cool well if the defrosting is not happening properly.

A dirty condenser may be the culprit for your refrigerator not cooling well. What will happen in case if the condenser is dirty is that it will cut off the extra load. That work is done by the thermostat on the side of the compressor in case the refrigerator heats more than usual. To rectify this problem clean the condenser coils using the vacuum cleaner. These are either behind or beneath the refrigerator
In case the refrigerator is not leveled, that too can lead to the refrigerator not cooling properly, because if the level is not right, the door of the refrigerator may not close correctly, causing cooling problems. If this is the case, it might be necessary to ensure that refrigerator is at level and is slightly tilted back. Do some adjustment to get that correct level using a wooden block or see if the screws on the leveling legs need some looking into.

Check out the door seal. If the door seal is worn out, it will definitely result in frost build up and that won't allow the door to close properly, thus the problem of refrigerator not cooling. In addition to that there can be a problem in the door even if the level and other things are fine. You would need something to do about the door then. May be loosen the hinges and fix them in order to get the correct position of the door. Eventually tighten the hinges.

The food and freezer sections will go dysfunctional if the evaporator fan is not working properly. This is because then there will be no airflow to the freezer or the other sections of the refrigerator. Confirm if both the fans are working well by listening to the sound emitted by them. There is a possibility that one may work and the other wont. For that, may be you would have to look for a blockage or something in the one which is not working. Even after doing this you do not find any problem in the fan, you may need to replace it. This are are the general procedure for troubleshooting refrigerator not cooling. with all this, you should be able to identify and fix the problem.

Take care.

My LG Refrigerator Freezer has the green temperature control lights blinking on and off. How can I stop it?

When the refrigerator and freezer reach the set temp, the blinking stops. – If the blinking does not stop, unplug the refrigerator for about 30 seconds to reset the processor. – If the display still blinks it may indicate a problem within the freezer.

Samsung rb215abbp won't stop beeping. I recently switched the door from the right side to the left. Now my fridge says 66 degrees but is cold. Light is on only when I unplug and plug it back in.

Fridge keeps beeping or buzzing: The following is for Frigidaire models but others can be addressed similarly.

Several Frigidaire refrigerator models have an electronic control panel on the freezer door the owner can use to adjust the internal temperature, dispense ice and water and receive notification about issues such as the need to replace a water filter. The refrigerators also emit a beep for various actions and as an occasional alarm. Determining what causes the beeps necessitates some troubleshooting.
Temperature Controls ·A Frigidaire refrigerator's display panel blinks when the control panel is touched to set temperature controls. After pressing "Freezer Temp" or "Refrigerator Temp" on the keypad, press the arrow buttons within five seconds to increase or decrease the desired temperature. If you do not press the arrow buttons within five seconds after pressing "Freezer Temp" or "Refrigerator Temp" on the keypad, the refrigerator beeps to indicate the current setting will stay in place.

Door Open ·When you leave the refrigerator or freezer door open, the refrigerator beeps. Also, the "Door Ajar" indicator illuminates on the appliance's display panel. Shutting the door and pressing "Alarm Reset" stops the beeping and turns off the "Door Ajar" indicator light.
·The Frigidaire refrigerator has a control lock feature that prevents use of its control panel or dispensers when the unit is locked. When the control lock is active, a beep sounds when a keypad or dispenser is pressed. Release the control lock by pressing the "Control Lock" icon for three seconds. A beep will sound, and the icon's light will go out.
Power Reset ·A power reset is occasionally necessary if the Frigidaire refrigerator's control panel does not work normally or a reset function on the keypad does not work. A power reset involves disconnecting power to the refrigerator by unplugging its power cord from the electrical outlet, waiting 30 seconds and plugging the power cord back into the electrical outlet. When the control panel resets, a beep sounds. If the refrigerator beeps even after a power reset and the beeps' source is not known, contact Frigidaire.

Refrigerator light stays on ?

LG has a wonderful way of turning on their refrigerator lights, they have the control board do it. Very nicely done in theory but in reality I would trust a handy door switch to control the light on/off function then a relay that get's stuck. That's right, the relay is stuck on the control board. Pull light bulbs out quickly before plastic melts on the inside top panel of fridge. Call LG, it should be covered under warranty.

Lights would not go out,overheated and burned out

Yes it is a stuck relay. LG has also come out with a new thermal disk in the light housing as well. This will stop it from melting, but at times you may not have a light on when you open the door. Get the new board and it will solve the problem.

Temperature Control

call the number in your service manual. they'll ask you to sent the receipr, the silver sticker on the back of the fridge, and a piece of the outlet cord so they know it's not in use. they'll ship you a new fridge. WOW!
