Please follow these important safety instructions to prevent the risk of fire, electric shock, personal injury, or damage when using the LG LSG4513BD range:

WARNINGS:

• Do not step or sit on the oven door. The range could tip, leading to injury from spilled hot liquid or food.

• Ensure the Anti-Tip Bracket packed with the range is properly installed and engaged. If the range is pulled away from the wall for cleaning or service, make sure the Anti-Tip Device is reengaged when the range is pushed back.

• Do not touch burners, grates, or the interior surfaces of the oven during and after use until they have had sufficient time to cool. These surfaces can become hot enough to cause burns.

• Do not store items of interest to children in cabinets above the range or on the back guard. Children climbing on the range to reach items could be seriously injured.

• Do not leave children unattended in the area where the appliance is in use. They should never be allowed to sit or stand on any part of the appliance.

• Never use your appliance for warming or heating the room.

• Flammable materials should not be stored in an oven or near surface units. Keep plastics, clothes, and paper away from parts of the appliance that may become hot.

• In case of a grease fire, turn off the oven to avoid spreading the flame. Smother the fire by closing the door or using a dry chemical, baking soda, or foam-type extinguisher. Do not use water on grease fires.

• Never block the air vents of the range. Air openings are located at the rear of the cooktop, at the top and bottom of the oven door, and at the bottom of the range.

CAUTIONS:

• Always use pot holders or oven mitts when removing food, as cookware and plates will be hot.

• Be careful when handling sheet metal parts, as sharp edges may be present.

• Be careful not to bend the convection fan blade, as this can result in vibration, noise, and poor performance.

• Be careful not to scratch or chip the oven liner paint when handling the oven light socket.

• Do not lift the oven door by the handle, as it is very heavy.

If you smell gas, follow these instructions exactly to prevent a potential fire or explosion:

• Do not try to light any appliance.

• Do not touch any electrical switch; do not use any phone in your building.

• Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.

• If you cannot reach your gas supplier, call the fire department.

Bake Mode: The bake burner operates during this mode. It is used for foods that are normally baked. The oven must be preheated for best results.

Convection Bake / Roast Mode: This mode is ideal for cooking casseroles and roasting meats. The oven should be preheated. This mode uses an “auto conversion” feature that automatically reduces the standard recipe temperature by 25°F (14°C), and the display will show this adjusted temperature. The oven fan runs during convection cooking but will stop if the door is open for more than 30 seconds.

Broil Mode: The broil burner operates during this mode. It is used for foods that are normally broiled. Preheating is not required. Foods should be turned at least once, except for fish.

5. Set the start time: press plus (+) until “4:30” appears in the display.

6. Press Start. A short beep will sound, and “Timed Delay” and the start time will appear. The oven will begin baking at the set start time.

To cancel a Delayed Timed Cook, turn the oven mode knob to the Off position.

The Timed Cook feature allows you to cook for a specific length of time, after which the oven will automatically turn off. This can be used with Bake, Conv. Bake, and Conv. Roast modes.

Example: To bake at 300°F for 30 minutes:

1. Turn the oven mode knob to select the Bake mode. “350°F” will appear.

2. Set the oven temperature: press minus (-) until “300°F” appears.

3. Press Cook Time. “Timed” will flash in the display.

4. Set the baking time: press plus (+) until “30:00” appears. The time can be set from 1 minute to 11 hours and 59 minutes.

5. Press Start.

When the cooking time has elapsed, “End” and the time of day will show in the display, and a tone will sound every 60 seconds until the oven mode knob is turned to the Off position.

When the oven has a malfunction during cooking, the cooking will be canceled, and an F-code will be logged in the EEPROM. This code will not display during normal operation. To check for a logged failure code, follow these steps:

1. With the oven off, press any button, and ensure the encoder is in the “Off” position.

2. Press the buttons in the following order: + then →_ then press and hold Oven light for 3 seconds.

If there is a malfunction, the oven will display the Failure Code (F-code) on the left side of the display and the time the failure occurred on the right. If there are no failures, the display will show “—“. After checking the code, move the Encoder to remove all codes from the display.

If your range has no power or display, perform the following checks:

1. Check the button beep: Touch the Clear button. If you hear a beep, the Main PCB may need to be replaced. If there is no beep, proceed to the next step.

2. Check Power Cord: Ensure the power cord is securely connected to both the wall outlet and the terminal block on the range.

3. Check Thermostat: Check the thermostat for continuity. It should show a “short” condition when normal. If it’s “open”, it needs to be replaced.

4. Check AC Input to SMPS PCB: Verify that there is 120V AC at the SMPS PCB connector CN01 (pins 1 and 3).

5. Check Connections between PCBs: Check the harness connections between the SMPS PCB (CN02) and the Main PCB (CN03). If reconnecting them does not solve the issue, the Main PCB may need to be replaced.

If the oven does not heat and an F9 error is present, follow these troubleshooting steps with the unit unplugged:

1. Check Connections: Ensure all electrical wiring connectors for the Relay PCB and heating elements (Bake igniter, Broil igniter) are secure and not loose.

2. Check Igniter Resistance: Measure the resistance of the bake and broil igniters. A normal reading should be between 45-400 ohms for a Norton Igniter or 50-500 ohms for an SIC Igniter. If the resistance is outside this range, replace the faulty igniter.

3. Check Thermistor (Oven Sensor): Measure the resistance of the thermistor at room temperature (approx. 25°C / 77°F). It should be approximately 1.09kΩ. If the resistance is incorrect, replace the thermistor.

4. Check with Test Mode: Plug the unit in and enter the service test mode to check the thermistor’s reported temperature. At room temperature, it should read between 70°F and 90°F. If the reading is incorrect, proceed to the next step.

5. Check Relay PCB: If the thermistor and igniters are functioning correctly, the Relay PCB may be faulty. If the problem persists after replacing the Relay PCB, the Main PCB should be replaced.

An F10 error indicates a problem with the door locking mechanism. This can occur if the door lock switch does not operate correctly after the lock motor rotates twice during a self-clean cycle start. Follow these steps with the unit unplugged:

1. Check Electrical Connections: Inspect the wiring and connectors for the Relay PCB, the door locking motor, the micro switch, and the CN31 connector on the Main PCB. Ensure all connections are secure.

2. Check Door Lock Motor: Press the Clock button for 3 seconds to attempt to operate the lock motor. If it does not operate correctly, proceed to the next step.

3. Check Micro Switch: Measure the resistance of the door lock micro switch. It is a normally open type switch, so it should show infinite resistance (open) when not activated and continuity (closed) when activated. If it does not function correctly, replace the micro switch.

4. Check Lock Motor Resistance: Measure the resistance of the lock motor. It should be approximately 2.6kΩ. If the reading is infinite or below 5Ω, replace the lock motor.

5. Check Relay PCB: If the motor and switch are normal, the issue may be with the Relay PCB. If the problem persists after replacing the Relay PCB, the Main PCB should be replaced.

An F1 error (Sensor open) or F2 error (Sensor short) indicates a problem with the oven temperature sensor (thermistor).

1. Check Connections: With the unit unplugged, check the sensor connection harness and the CN31 connector on the Main PCB to ensure they are not disconnected or loose.

2. Check Thermistor Resistance: Measure the resistance across pins 4 and 5 of the CN31 wiring harness (which connect to the thermistor). At room temperature (25°C / 77°F), the resistance should be approximately 1.09kΩ. If the resistance is incorrect (infinite for F1, near zero for F2), the thermistor is defective and must be replaced.

3. Check with Test Mode: Plug the unit in and enter the service test mode to view the current oven temperature. At room temperature, it should display a value between 70°F and 90°F. If the value is abnormal, there is an issue with the sensing circuit.

4. Check PCBs: If the thermistor and wiring are confirmed to be good, the issue may lie with the Relay PCB or the Main PCB. Replace the Relay PCB first. If the problem continues, replace the Main PCB.

An F6 error indicates that the oven temperature has exceeded 650°F continuously for 2 minutes. This suggests a problem with temperature regulation, likely a stuck relay.

1. Check Thermistor: Unplug the unit. Verify the resistance of the oven thermistor is normal (approx. 1.09kΩ at room temperature). An incorrect reading could cause the oven to overheat.

2. Check Heater Relays: With the unit unplugged, measure the resistance across the heater relay terminals on the Relay PCB (Broil igniter relay RY12 and Convection igniter relay RY11). The resistance between the relay and the “Live” terminal should be infinite. If it shows a short, the relay is stuck closed and the Relay PCB must be replaced.

3. Check DLB Relay: Also check the DLB (Double Line Break) relay (RY13). It should also show infinite resistance. If shorted, replace the Relay PCB.

4. Check with Test Mode: If all components test normal, plug the unit back in and use the test mode to verify the thermistor reading is accurate. If the problem persists, replace the Main PCB.

An F7 error indicates the convection fan is not operating correctly.

1. Check Fan Motor Resistance: Unplug the unit. Measure the resistance of the convection fan motor windings.

• Fan High: Approximately 25 Ω ± 10%

• Fan Low: Approximately 30 Ω ± 10%

If the resistance is incorrect, replace the fan motor.

2. Check Fan Relays: Measure the resistance of the fan motor relays on the Relay PCB (RY8 for High, RY9 for Low) and the “Live” terminal. The reading should be infinite. If it’s shorted, the Relay PCB is faulty.

3. Check Connections: Ensure all harnesses and connectors associated with the convection fan and its path to the Main PCB (CN42) and Relay PCB (CN53) are secure.

4. Check Main PCB: If the fan motor, relays, and connections are all good, the issue may be with the Main PCB. If the same phenomenon occurs after checking all connections, replace the Main PCB.

An F3 error indicates a shorted button on the keypad or a communication failure with the touch interface.

1. Check Connections: Unplug the unit. Check the connecting states between the Key pad (Glass Touch PCB) and the CN03 connector on the Main PCB. Ensure the connection is secure.

2. Replace Control Panel: If connections are good, the issue is likely with the control panel (Glass Touch PCB). Replace the control panel.

3. Check with Key Test Mode: After replacing the panel, enter the service test mode to check button operation.

4. Replace Main PCB: If the button is still not operated correctly after replacing the control panel, replace the Main PCB.
