LG Refrigerator not cooling

Probably your ice-maker's circuit is a victim of power surge. Guess you'll have to call your friendly refrigerator repairman.
To avoid this kind of damage, or even worse because surge can burn out your refrigerator's main circuits, codenser, etc... buy a surge protector

Electronic Surge Protector for Refrigerators up to 27 Cuft and Freezers
Of course, you don't need to get it from Amazon; look for it at your nearest home depot or retail store, Wlamart etc...

Hello Charles;

My name is Peter. I am a retired field service refrigeration technician.

In your owners manual, it is recommended that you have a surge protector on your unit. In fact, any appliance including your television, home computer requires a surge protector.

At your local Home Depot, Ect. you can purchase individual wall socket surge protectors for about $20.00. They are a well worth investment.

Your board reset button is not going to work. The power shut down and restarting surge blew out both your control board and control board capacitor.

As a field service refrigeration technician, I carried no less than 3 LG control boards in my truck. 65% of my service calls were LG & Samsung. The fewest service calls I had were Amanda & Kitchen Aid, follower by GE and Kenmore.

Anyway, You need to replace both the control board (Part Number LMX25981ST - $122.00) and your control board capacitor (Part Number OCZJB20146 - $27.00).

You can get a lower price searching on the internet.

You have already accessed your control board.

So, lets replace the control board and capacitor.

1.) Un plug your unit.

2.) First ground yourself, static electricity will nock out your board. Rub your hands across something that is steel. Do not wear wool clothing.

3.) Your new control board will come in a anti-static silver bag.

4.) The control board is held in by several white pins. On the two sides of these pins are clips you must squeeze in to pull the board out.

5.) Systematically, remove one connector from the old board to the new board. The connectors have a locking tab at the top, squeeze the tab to remove. When inserting on the new board make sure these clips are locked in.

6.) replace the capacitor next to the board.

7.) Reattach the control board cover plate. Plug your unit back in. Allow 24 hours or less for the unit to balance the high pressure (160 PSI) liquid and the low side (65 PSI) vapor side.

Melissa I think you hit the nail on the head! If it was running great before power outage, and problems started after! Power Surge sounds correct to me! below is a link for the service manual! As for board, sounds likely! Check the board for burnt fuses, I think there is 2. Sorry i can't help You more! Good luck!

I guess the pests are fruit fly or white fly from any fruit you may have left. Leave the door open . Switch off the fridge . Use a fly spray. Clean the fridge with warm soapy water and vanilla ( soapy water leans the fridge while vanilla clears the odours) Close the door and turn on. Next time let the fridge run as it consumes very little power if the door is not opened and is ready for use on return.

Your power outage may have been caused by a nearby lightning strike, or any number of
1000 different reasons that cause power surges, brown-outs, voltage spikes, inductive loading,
and/or utility pole breaker trips and resets (this accounts for your power loss (a pole breaker trip),
followed by restoration of power (the pole breaker automatically reset) - even plain old high electrical demand causing an overload due to air conditioning demands caused by hot weather.
When the pole breaker reset, your TV caught a power surge.
Whenever a power outage occurs, quickly power off (or better, unplug) any/all computers, TVs,
etc. that are not protected by surge-protection.
As an electrician, when someone loses an item of electronics concommitant to an electrical
anomaly, its almost
always traceable to a nearby lightning strike (or the power company provided equivalent), accompanied by inadequate surge protection for
the VCR/TV/Computer/Stereo/uninsured valuable electronic item/XBOX 360/Nintendo Wii.
Surge protection can
be provided by the consumer at the power strip (a good one with builtin MOV protection and a
warranty costs $20, whereas a zero-protection 4-outlet or 6-outlet power strip will cost $4-$5).
Your electrician can provide whole-house surge protection where a whole-house MOV-based (metal oxide varistor) surge protector, or per-circuit protection can be installed with
a GFCI breaker (or better, an AFCI breaker) can be installed.
GFCI = ground fault circuit interruptor
AFCI = Arc fault circuit interruptor
Lightning protection is especially important in Florida, which is the "lightning capital of the world."
I've never found a good solution to lightning-fried electronics (random power supply components are destroyed and/or fuse blown), other than renters insurance or homeowners insurance.

Your only real hope for an economical fix is to look for a blown fuse, and replace it.

If desperate to attempt a fix on your own, you could try replacing the entire TV power supply as a module, but even this provides
no guarantee of a fix - lightning damage can extend beyond the power supply.
When traveling, I will always unplug everything before I leave (except the security system),
and also turn off the breakers to unneeded house circuits (which kills the wall switches that
control interior lighting - forcing a burglar to use their flashlight instead of interior lighting)
which is the least convenient lightning protection, but highly effective, and cheap (free).

Hi,

Many times a freezer and/or refrigeratordo not work right because of a dirty condenser coil...there are also many otherthings that can go wrong. If you are hearing a clicking or buzzing thencheck 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 starttrouble shooting your unit...and something that you can do rather then callinga repair person to do a simple thing for you...

Follow the hose from the coolant reservoir to the engine. The thermostat is behind the housing where at hose connects. Below are instructions from autozone.com. Recommend you also read my post at http://www.fixya.com/cars/r5929960-s_thermostat, and thanks for using FixYa.

1. Drain the cooling system.
2. Remove the air cleaner.
3. Remove exhaust crossover pipe.
4. Disconnect the surge tank line fitting from the coolant outlet.
5. Remove the thermostat housing to intake manifold bolts.
6. Remove the thermostat housing outlet and thermostat
7. Clean the mating surfaces.

To install:

1. Install the thermostat and housing outlet.
2. Install the thermostat housing bolts. Tighten the thermostat housing bolts to 18 ft. lbs. (25 Nm).
3. Install exhaust crossover pipe.
4. Connect the surge tank line fitting to the coolant outlet. Tighten the fittings to 15 ft. lbs. (21 Nm).
5. Install the air cleaner.
6. Fill the cooling system.
7. Inspect the system for leaks.

Are you having any cooling problems whatsoever, anywhere? Is there any area in the unit that you dont put food for cooling reasons? if cooling is fine, check the water pressure as it comes into the refrigerator, you wil have to disconnect the water line at the solenoid valve behind the fridge. If pressure is good, pour 4-8 oz of water into ice maker, does it eject those cubes within 24 hours? then replace your water valve(s) One assembly houses a solenoid for both the ice maker and the water dispenser, both solenoids are bad.

If the fan inside the freezer is running and the compressor behind the fridge is running and is hot to touch, you have a gas problem or the compressor is inefficient. This can only be confirmed by connecting refrigeration gauges to the gas system and should only be performed by a fridge tech.
