How to Use Smart Diagnosis on LG Refrigerator?

LG refrigerator models are known for being easy to use and maintain. You might want to clean out the condenser coils or replace the evaporator fan motor. In such cases, you’ll need to know how to access specific components inside the fridge.

Step 1:

1. Open the door of the refrigerator.

2. Turn off the compressor.

3. Remove the cover panel above the freezer compartment.

4. Pull the ice maker tray out of the freezer compartment.

5. Lift up the bottom panel of the freezer compartment. You’ll see a small hole near the front edge of the unit. This is where the evaporator fan motor is located.

6. Locate the fan motor. If you’re unsure about where to look, turn on the light switch next to the fan motor. The lights will illuminate.

Step 2 – “Touch the mic icon.”

The next step involves touching the microphone icon on your smartphone. You’ll hear a loud chirp, followed by a recording of what you say.

“Step 3” – “Click the start button.”

Once you’ve recorded your voice, it’s time to click the Start button. An on-screen notification lets you know that your refrigerator is now listening.

“Step 4” – “Wait for the chime.”

You’ll hear a sound once the analysis is completed.

Step 5 – “Analyze”

Open the right refrigerator door and put your phone next to the brand logo. Touch the record icon on your mobile device. See a red circle pop up. Tap it to begin recording.

Now you’re ready to analyze.

Touch the start button on the refrigerator to begin analyzing.

You’ll see a list of items in the fridge and a bar graph showing how much food each item needs.

The system uses machine learning to identify what foods will likely go bad soonest. For example, the system will tell you if there’s something wrong with the milk.

If you want to know why certain items aren’t being used, tap the info button to learn more about the food.

To add more products, just open the app again.

Step 6 – How To Create A Countdown Timer Without Using Code Or Creating A Web Service

If you want to ensure people don’t miss important events, you’ll probably use a countdown timer. You could either build one yourself or find a ready-made solution online. If you’ve ever used a countdown timer, you know how annoying it is to wait for something to finish counting down. But what if you’re running out of time? What if you just wanted to tell someone that something is happening soon?

You might think you’d have to write some JavaScript or build a web service to do this, but you actually don’t. You can use a simple audio file called “step.”

The step format is pretty straightforward. It consists of three parts:

1. A start tone

2. An end tone

3. A pause tone

When played together, these three sounds indicate the beginning and end of the countdown.

Error Codes – How to diagnose?

Er CF

A common problem with refrigerators is the compressor clutch. This part controls the flow of air into the evaporator coil. If it fails, you’ll see a “CF Error Code 5.”

The fan motor is located near where the compressor is mounted. You’ll find it under the unit. Three screws hold the panel together; remove those and pull off the entire panel. Look inside the area behind the fan motor, and you’ll find the clutch assembly. Remove the cover plate to access the clutch.

Er d5 or Er dS

The Boleslavsky Variation of the Sicilian Defence is one of the most popular openings in chess history. It is often considered the best opening move ever played. This variation was named after Mikhail Botvinnik, who used it against Bobby Fischer in their famous match in Reykjavík in 1972.

In the game, Black plays…d5, while White plays c4. The main idea behind this move is to open up lines along the e1–g7 diagonal. The white bishop takes over the role of the knight, moving into position to attack the black king. However, Black gets some counterplay on his kingside, thanks to his rook.

Er FS or Er F5

Er gf or er f fail? Do you know what it means?

If you’re having trouble finding the cause of a problem, you’ll want to check the following things:

1. Check the battery terminals.

2. Make sure there are no loose wires.

3. Look for signs of corrosion.

4. Is the hood open?

5. Is the radiator cap off?

6. Does the fan spin?

7. Are the lights working?

8. How about the headlights?

9. What about the tires?

10. Have you checked under the hood?

Er gf or er f failure? Do you know what this means?

If the parts don’t work correctly, replace them. You should never try to fix a problem yourself unless you’ve been trained to do so. And even then, make sure you know exactly what you’re doing.

Er H5 or Er HS

The most common cause of an overheating problem is a faulty heat exchanger. This is usually caused by a defective fan motor or a clogged air filter. If you notice smoke coming out of the exhaust pipe, there may be problems with the catalytic converter. Check the coolant level and replace it if necessary.

Check the thermostat housing for cracks or leaks if the temperature gauge reads high. Also, check the hoses connecting the heater core to the thermostat housing. There might be a leak somewhere. You can test the system by turning off the ignition switch and opening the hood. If the engine does not start, turn the key again and wait about 30 seconds. Then close the hood and try starting the car again. If the engine starts, repeat the process to find the source of the problem.

Another reason for overheating is too much water in the cooling system. Remove the hose leading to the overflow tank and let the water run into the ground. Replace the hose and tighten the connection. Ensure the radiator cap is tight and the drain plug is accessible.

A third possibility is that the heater core is blocked. Turn off the power to the heater and open the hood. Disconnect the positive battery cable from the negative post on the starter solenoid. Release the parking brake and allow the engine to idle while holding down the accelerator pedal. Let go of the gas pedal and observe what happens. If the engine stops running, release the brakes and restart the car. Repeat the procedure several times. Remove the spark plugs and clean the combustion chamber if the engine still won’t start. Reinstall the plugs and retest.

The heater core is likely damaged if none of the above remedies work. Take the car to a repair shop.
