Dont be so quick to assume its ur power board?

Fridge not starting? CLICKING? FIRST ALWAYSCHECK FORpower at the outlet,checkfor 120 volts.

MAY HAVE A BAD START RELAY OR CAPACITOR ON THE COMPRESSOR , CAN BUY A INEXSPENSIVE 3 IN 1 HARDSTART KIT AND BY PASS THEM , NOT THAT HARD TO DO, COMES WITH INSTRUCTIONS> BY THE WAY DO U HEAR ANY CLICKING SOUNDS FROM COMPRESSOR? BUT U MAY ALSO WANT TO CHECK UR COLD CONTROL THERMOSTAT IF IT GOES BAD U MAY GET A NON START ALSO HAVE IT CHECKED FOR PROPER VOLTAGE AND OHMS RESISTANCE WHEN IN THE ON POSITION
A BAD DEFROST TIMER CAN SHUT DOWN COMPRESSOR HAVE IT CHECKED WITH MULTI METER.

to check the defrost timer, u can get by and test manually by placing a small screw driver into the tiny slot or hole underneath the timer and turn slowly clockwise till u hear 1 click. this will engage ur defrost cycle in about 15 minutes u should be able to come back and feel the heat in freezer as it melts the ice providing ur terminator is not bad?
Another way to test it is with a multi meter. Remove timer it from fridge and you will see 4 prongs numbered 2,1,4,3 in that order. Place ur meter prong on prong 1 & 3 (if your fridge has a capacitor wired in series with the windings, then u check for micro fares rather than OHMS) If u cannot confirm this test, still try the next.
Take ur meter prong and connect to prong 1 & 4, it should read resistance or ohms ( closed) now remove prongs and place on prong 1 & 2, this should now read infinity or open (no ohms) now take a small screwdriver place it in the tiny hole or slot under the timer. Turn it clockwise slowly till u hear 1 click. Now ur 1& 2 should read closed ( showing ohms or resistance) now place meter prongs on 1 & 4 and you it should now show open ( or no resistance - no ohms) this is how u know ur timer is good, Remember when testing for ohms ADJUST meter to use a high ohms rating in the thousands as the resistance is very high in OHMS. And adjusting to low ohms rating may give a false reading or not show the proper resistance..


AT TIMES YOU MAY HEAR THE COMPRESSOR CLICK OFF AND ON OVER AND OVER. Signs of a bad start relay or capacitor. Check with an OHMS meter for continuity (ohms) and voltage, capacitor can be checked for Microfares.
To check ur compressor with multi meter:
Disconnect and remove the relay and capacitor from compressor, somes located next to compressor in a casing.

You wills see 3 prongs coming out of compressor. 1 goes to ur srtart winding, 1 goes to ur run winding and the center goes to ur ground.

Place ur meter connector or prong on the start prong and the other on the ground (center prong) take note of the reading in OHMS for example 5 ohms.
Next place meter prong on run prong and the center ground prong agin. Take note of the reading in OHMS. Example 4 ohms

Next place meter prong on the start prong and the other on the run prong, now take note of the reading example 9 ohms. Now match the total of this ohms test with the total of ur two separate test. 9 ohms, if they match ur ok give or take 5 percent plus or minus. One more test to make to test of there is a short in compressor attach meter prong to ground prong and rub the other end of meter prong to metal ( scrape the metal clean of paint and test on metal surface not painted surface. If it shows continuity or ohms , u have a short in ur compressor. It should show infinity

SOURCE: where can i buy a circuit board for my lg refrigerator model lfc23760st

No need to buy a new main control board !
The problem is mainly from the fuse that soldered in the main control board, go to buy a "125V 15A or 250V 15A" fuse ($5.00 a pack of 5 pcs), cut the burnt fuse from the board, re-soldered the new fuse into the board, the refrigerator work again. you save $80 for the labour cost of the technician and $180 for the cost of a new main board.

Why is my LG french door act like is has no power?


Probably a bad fuse on the main board. Fuse is not replaceable so either you have do a workaround (search LG refrigerator fuse repair for several fix videos and how-to's) or you have to replace the whole control board (part EBR41531302 I believe, but double check with your the part vendor before ordering).

Check the fuse by pulling the refrigerator out, unplugging, taking off back control board panel, and checking the fuse for continuity.

Replaced main board but still no cooling. now what? the power board?


Compressors cool the fridge, the main controller does all the electrical commands, i'd check if the compressor is cutting in if it does then there is a gas or fan problem.

Refrigerator does not appear to be getting power, no lights, don't here motor running


If you have no lights or hear the motor running, I would check the house circuit breaker first and measure the voltage at the outlet. If that is within specs then the one thing that could cause your problem in the refrigerator is the power control board P/N: 6871JB2047A

So like everyone else, my LG LFC23760ST lost all power. Thanks to this website, I figured out what to do! fuse1 on the main board blew up which I had someone to solder in a new one. However, now that power...


Sorry to read about your problem, I hope this helps you out.

The defect that caused the fuse to blow, is still their. and you still have the problem that caused the fuse to blow...i assume the board is defective and will have to be replaced..but the main problem, still has to be found.

Our refrigerator LG Model #LFC23760 just quit working. We checked the plug and it is good. Not sure what to do next. There is no power to the unit. Nothing is working.


fuse blew, if you have a contract have it repaired but try to keep the old mother board. (they just throw it away anyway, otherwise they are not authorized to work on LG units) you will see the culprit fuse. have it replaced in an electronic shop, (have them put in a fuse holder) and keep a few extra fuses Just in case... next time you could replace the board yourself.

Lfc23760st stopped working


You have a blown fuse on the main board. It can be replaced with a new 20 amp glass fuse using a soldering iron. Remove the cover and check the fuse if it is burned that is your problem

You have a blown fuse on the line incoming voltage circut. Remove the main board cover on the back and look for a glass metal ends 20 amp fuse. You can remove the fuse carefully with a soldering iron and solder a new one back in and you will be running again!
