20 Most Recent LG LRSC21934 Side by Side Refrigerator Questions & Answers

Usually a small leak in the water line from water valve to the water filter.
I have seen when moving a ref the movers catch the plastic water line on the back of the box on the home door to the outside and damage it.

Pull out the Ref. and inspect the tubing.

Be sure to protect your floor.

If your house water supply to the refrigerator is poor it is most likely the cause of the water dispenser and ice maker not working. If you hear the water valve humming when the water dispenser is depressed and no water is dispensed it is most likely poor or restricted water flow to the refrigerator. If you live in an older home the water supply shutoff valve to the refrigerator is usually in the basement or under the kitchen sink. Many shutoff valves are called a saddle valve and the valve is secured onto a cold water pipe and as the valve is turned clockwise a pin punctures the water pipe allowing water to flow. Saddle valves often become clogged with minerals and can completely block water flow to the refrigerator,. If the valve is corroded on the outside it should be replaced. Ice maker installation kits are available at most hardware stores. Copper water line kits are preferred. Cost is under $25.00. If the Saddle valve is in good shape they can be taken apart and cleaned. Be sure to shut off the main house water and drain pipes before attempting to clean. Newer homes may have a water box in the wall behind the refrigerator. Sometimes these can become clogged with mineral deposits as well. Hope this helps. Mike

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...

You have a faulty main board. And possibly more problems. Contact an authorized LG repairman to resolve this as it can be a difficult problem to diagnose.

If it's not a defrost problem then it will be a freon/compressor problem which has a 5 year warranty.

The evaporator coil behind the cover on the back wall inside the freezer will ice up under normal conditions. Every 8 to 10 hours for around 20 minutes the defrost timer (or in most newer models the electronic adaptive defrost control) will turn the defrost heater on to melt the built up ice. There is a defrost thermostat which prevents the heater from overheating the freezer by breaking the heater circuit when the temp reaches close to 32 degrees F. The entire cooling system shuts off during the defrost cycle and starts back when the timer advances through the cycle.

If this ice is not melted it will continue to build up until the air can’t flow over the coil to circulate the cold air through the freezer and into the fridge. The temperature change in the fridge is usually noticed first followed by the freezer.

If the defrost thermostat is bad it can prevent the heater from coming on OR it won’t turn the heater off when it gets too warm. It is clamped to the evaporator coil at the top to sense the temp. If it appears to be misshapen it is bad.
With an ohm meter it should show continuity when cold and none when warm.
You can also bypass the thermostat to see if the heater comes on then. If it does then you know the thermostat is bad and needs replaced.

The defrost heater is located on the evaporator. It is in a tube which is at the bottom and can also go up the sides of the evaporator. On some types you can see a burnt spot if it’s bad. With an ohm meter it should show continuity from end to end when disconnected from the wiring in the freezer. You can also test the wiring for voltage when it’s in the defrost mode.

If you have a defrost timer you can test it. It can be located under the fridge behind the kick panel on the front. Some are in the fridge with the controls at the top. You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer because that means the timer is not running. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

If you have an adaptive defrost control instead of a timer, replace it if the heater and thermostat test good. It is located in the fridge with the controls in some models and on the back in others.

I suspect you are talking about the area between the doors. Refrigerators use a loop off the compressor to warm this area to prevent condensation from forming there. Older refrigerators sometimes used an electric heater there, but of course that increases energy consumption. You will notice that the area is much warmer when the compressor is running. All this is normal, and saving you energy.

Look for the air ciculation regulator sliding vent between frig & freezer section open accordingly. Set both sides to #3 on dials if frig not cooling to less than 40 degrees, might need new cold/temp controller behind frig dial

You should barely be able to hear the compressor. You should only hear the freezer fan when you open the door. If something has gotten into the freezer fan, maybe you can remove it's cover to check.

Make sure your door fits good and flat. I run a piece of paper all around it to check the seal. Close the door on the piece of paper and try to slide it. Check all around.

Check freezer... for Frost build up and if Fan is blowing, Check condenser... To make sure clean, and the fan is blowing by compressor, Check Recirclating Vents in refrigerator... to make sure theres no blockage, CONTROLS ...should be in the middle setting,

Try pulling the cover off in the back of the fridge and see if the fan is still operating when you push the light sensor switch in but hold it down for at least 10-20seconds to see if it starts.

Fridge freezing up- and no fan or air circulation: AT TIMES The fan usually stops working due to ice obstruction when the defrost terminator has gone out and u get ice build up? u can check the terminator with a multi meter for continuity but do not check at room temperature. stick the terminator in cup of ice water for 20 minutes then check it for continuity, should be closed when cold and open at room temperature. May also need to check the defrost timer, The defrost timer is usually found behind the front grill "toe kick" of the refrigerator. Or in the fridge compartment near middle top section. 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.. Another item to check with a meter is the heating element itself. Located under the evaporator coils. It should show continuity or resistance OHMS WHEN TESTED AT BOTH ENDS OF THE PRONGS . Lastly check the cold control thermostat with a meter for both OHMS and volts ( VOLTS is a live test with fridge plugged in so be careful) It must show 110 volts. An open or thermostat that reads infinity will not allow the proper cooling and defrosting cycles to operate and may in fact stop anything from happening as if there is no power to the unit? ALSO CHECK THE AIR FLOW VENT SYSTEM and THERMISTORS At times it can get stuck to far closed or open. Some units feature a digital electric adjusting vent system while others are manually set. Check for any ice build up or other obstruction in the vent damper, see if u can manually open or close it. Some times when u have the settings set to the highest it closes off one area while allowing to much cold air flow to the other area! THERMISTORS in the freezer and fridge section for continuity OHMS and for amount of OHMS current being put out. In most models around 1300 ( give or take 150 ohms) ohms is required God is so good: so this is why I give free advice so please thank him not me.
