Replacing the Drawer:

1. Pull the bearing glides to the front of the chassis glide.

2. Align the glide on each side of the drawer with the glide slots on the range.

3. Push the drawer into the range until the levers “click” (approximately 2 inches in).

4. Pull the drawer open again to fully seat the bearing glides into position.

5. Replace the two screws.

If your LG LSG4513ST oven has a malfunction during cooking, it will cancel the operation and log an F-code in its memory. The code will not display during normal operation. To check for a stored failure code:

1. Ensure the oven mode is set to Off. Press any button to wake the display.

2. Press the buttons in the following sequence: Press “+”, then press and hold “Oven Light” for 3 seconds.

If there is a malfunction log, the display will show the F-code on the left side and the time of the failure occurrence on the right side. If there are no failures, the display will not show an F-code. After checking the code, move the Encoder knob to clear the display and return to normal operation.

If your LG LSG4513ST range fails to power on or the display is blank, follow these troubleshooting steps:

1. Check Power Cord: Ensure the power cord is securely plugged into the wall outlet.

2. Check Circuit Breaker/Fuse: Check your home’s circuit breaker or fuse box to ensure the circuit for the range is on and has not tripped.

3. Check Terminal Block: Verify that the connections at the terminal block on the back of the range are secure.

4. Check Thermostat: An open thermostat can cause a loss of power. This may require a service technician to check.

5. Test Button Beep: Press a button on the control panel. If you hear a beep but the display is blank, the main control board (Main PCB) may need to be replaced. If there is no beep, there is likely an issue with the power supply to the unit.

If these steps do not resolve the issue, the unit may require service from a qualified technician to check internal components like the SMPS PCB and wiring harnesses.

If your LG LSG4513ST oven is not heating or displays an F9 error code, please perform the following checks safely. First, unplug the unit from the power outlet.

1. Check for Loose Connections: Visually inspect the wiring connections to the Bake and Broil igniters and the oven’s heating elements. Ensure they are secure.

2. Check Igniter Resistance: After the oven has completely cooled, a service technician can measure the electrical resistance of the bake and broil igniters. A normal reading is approximately 45-500 ohms. If the reading is outside this range, the igniter may need to be replaced.

3. Check Oven Sensor (Thermistor): The oven sensor’s resistance should also be checked. A normal resistance is approximately 1.09kΩ at room temperature (77°F / 25°C). If the sensor is faulty, it will cause heating issues.

4. Test Mode Check: You can use the oven’s test mode to check the thermistor’s reading in real-time. The value at room temperature should be between 70°F and 90°F. If the reading is incorrect, it indicates a problem with the sensor or the control board.

If these checks do not identify the issue, the problem could be with the Relay PCB or the Main PCB, which would require professional service.

An F10 error code on your LG LSG4513ST indicates a Door Lock System Failure. This means the oven’s control circuit has detected that the door lock motor did not operate correctly, typically during a self-clean or lockout function.

To troubleshoot this issue, follow these steps after unplugging the range:

1. Check Door Lock Operation: Plug the unit in. Press the Clock button for 3 seconds to activate the lockout feature. Listen for the motor and try to open the door. If it locks and unlocks correctly, the issue may have been temporary.

2. Inspect Wiring: Unplug the range. Check for any loose or disconnected wires at the door lock motor, the micro switch, and the connections on the Main PCB (connector CN31) and Relay PCB.

3. Test Components: A qualified technician can test the resistance of the door lock motor (normal is approximately 2.6kΩ) and the continuity of the door lock micro switch. If either component fails the test, it will need to be replaced.

If the wiring and components are all functional, the problem may lie with the Relay PCB or the Main PCB, which would require professional diagnosis and repair.

An F1 (sensor open) or F2 (sensor short) error on your LG LSG4513ST indicates a problem with the oven temperature sensor (thermistor) or its circuit. This sensor is crucial for regulating the oven’s temperature.

To troubleshoot, first unplug the range:

1. Check Connections: Inspect the sensor’s wire harness connection to ensure it is secure. Also, check the connection of the harness at the Main PCB (connector CN31).

2. Check Sensor Resistance: A technician can test the resistance of the thermistor. The sensor should be at room temperature for an accurate reading. The normal resistance is approximately 1.09kΩ at 77°F (25°C). If the resistance is infinite (F1 error) or near zero (F2 error), the thermistor is defective and must be replaced.

3. Enter Test Mode: If the resistance seems correct, you can use the oven’s test mode to see the temperature reading from the sensor. At room temperature, it should display between 70°F and 90°F. An incorrect reading here points to a faulty sensor or a problem with the control board.

If the sensor and its wiring are confirmed to be good, the issue may be with the Relay PCB or the Main PCB, requiring professional service.

An F6 error code indicates that the oven temperature has exceeded 650°F continuously for 2 minutes, signifying an “Oven hot” condition. This is often caused by a malfunctioning component that fails to shut off the heat.

After unplugging the unit and letting it cool completely, here are the troubleshooting steps:

1. Check the Oven Sensor (Thermistor): An inaccurate sensor can cause the oven to overheat. Check its resistance at room temperature; it should be approximately 1.09kΩ. If the reading is incorrect, the sensor needs replacement.

2. Check Heater Relays: The problem is often a stuck or shorted relay on the Relay PCB. A technician can measure the resistance across the heater relay contacts (for both bake/broil and convection). The reading should be infinite (open circuit). If there is continuity (a shorted relay), the Relay PCB must be replaced.

3. Check DLB Relay: Similarly, the Double Line Break (DLB) relay should be checked. It should also show infinite resistance when not powered.

If the thermistor and relays test normal, the issue may be with the Main PCB, which controls the relays. This requires diagnosis by a qualified service technician.

An F7 error code on your LG LSG4513ST indicates that the convection fan motor did not operate when it was supposed to during a convection cooking cycle.

To troubleshoot, please unplug the range and check the following:

1. Check for Loose Connections: Ensure all wiring harnesses associated with the convection fan are securely connected at the fan motor itself and at the Relay PCB (connector CN53).

2. Check Fan Motor Resistance: A technician can measure the resistance of the fan motor windings. The approximate values should be:

• Fan High: 25 Ω ± 10%

• Fan Low: 30 Ω ± 10%

If the resistance is incorrect, the fan motor needs to be replaced.

3. Check Fan Relays: The relays that control the high and low speeds of the fan are located on the Relay PCB (RY8 and RY9). A technician can check these relays for proper function. If a relay is faulty, the Relay PCB will need to be replaced.

If all components and wiring are found to be in good condition, the issue may be with the Main PCB, which sends the signal to operate the fan.

An F3 error on your LG LSG4513ST indicates a “Key short” error or a communication failure with the touch control panel. This can also manifest as some or all buttons being unresponsive.

Please unplug the range from the power outlet and perform the following check:

1. Check Connections: The primary cause of this issue is often a loose connection between the touch keypad (Glass Touch PCB) and the Main PCB. Carefully check the ribbon cable and connectors (CN03 on the Main PCB) to ensure they are clean, undamaged, and securely seated.

2. Run Key Test Mode: If the connection seems fine, you can use the built-in key test mode to check the operation of each button. If the button presses are not registered correctly in test mode, it points to a faulty control panel.

3. Replace Control Panel/Main PCB: If reconnecting the cables does not solve the problem, the issue is likely a faulty control panel (Glass Touch PCB). If a new control panel does not fix the issue, the Main PCB may be the cause and would need to be replaced by a service technician.
