LG LMVM2033SW (01) PDF DOCUMENT

Please observe the following precautions for safe operation of your LG LMVM2033SW microwave oven:

General Use:

• Do not operate or allow the oven to be operated with the door open.

• Before use, make the following safety checks: (1) Interlock operation, (2) proper door closing, (3) seal and sealing surfaces (for arcing, wear, and other damage), (4) damage to or loosening of hinges and latches, (5) evidence of dropping or abuse.

• Never operate the oven with no load. Operating the oven empty may shorten the life of the magnetron. When cooking small amounts of food or dry foods like bread, always place a glass of water inside the cooking compartment.

• Avoid using aluminum foil as it can disrupt cooking and cause arcing. If used, small pieces should be kept at least 1 inch (2.5 cm) away from any side wall of the oven.

• Never injure the door seal and front plate of the oven cavity.

• Never put anything into the latch hole and the interlock switches area.

During Servicing (by qualified personnel):

• The microwave oven is high-voltage and high-current equipment. Extreme care should be taken during repair.

• Before touching any parts of the oven, always unplug the power cord from the outlet.

• Personnel should not be exposed to microwave energy which may radiate from the magnetron if improperly used or connected. All microwave connections, waveguides, flanges, and gaskets must be secure.

Precautions on Installation:

A. Plug the power supply cord into a 120V AC, 60Hz, single-phase power source with a capacity of at least 20 amperes.

B. Avoid placing the unit in a location where there is direct heat or splashing water.

C. Install the unit on the mounting plate firmly.

D. Place the unit as far away as possible from TVs, radios, etc., to prevent interference.

Grounding Instructions:

For personal safety, the LG LMVM2033SW appliance must be fully grounded at all times. In the event of an electrical short circuit, grounding reduces the risk of electric shock. The plug must be plugged into an outlet that is properly installed and grounded.

This unit is equipped with a 3-prong plug for your safety. If the wall outlet is a grounded 3-hole type, the unit will be grounded automatically.

Warning: Improper use of the grounding plug can result in a risk of electric shock. Do not, under any circumstances, cut or remove the third ground prong from the power cord plug.

You can check the humidity sensor and an internal thermistor using the self-diagnosis mode on your LG LMVM2033SW. Follow these steps:

1. Press the “Defrost weight/time” button for 2 seconds.

2. The unit will display “TEST” and beep once.

3. The unit will then check the internal sensors.

4. If the unit is normal, it will beep and display “PASS”.

5. If it has an error, it will beep and display an error code.

6. Press the “Clear” button to return to Standby mode.

If the self-diagnosis mode detects an issue, it will display one of the following error codes:

These errors indicate an issue with internal components and require professional service.

If your LG LMVM2033SW shows no display or appears to have no power, follow these troubleshooting steps:

1. Make sure the power cord is securely plugged into a working wall outlet.

2. Check your home’s circuit breaker or fuse box to ensure the outlet has power. Reset the breaker or replace the fuse if necessary.

3. If the outlet has power but the oven still doesn’t turn on, the oven’s internal fuse may have blown. This requires professional service to diagnose the cause and replace the fuse.

If the keys on the control panel are not working, try the following:

1. Ensure the door is completely and securely closed. For safety, most keys will not operate if the door is open. The START key is one exception, but the oven will not begin cooking.

2. Try unplugging the microwave from the power outlet for 60 seconds, then plug it back in. This will reset the control panel and may resolve the issue.

3. If the problem persists after these steps, the keypad or control board may be faulty and will require professional service.

If your LG LMVM2033SW runs (light on, fan running, turntable rotating) but does not heat food, check the following:

1. Ensure the door is securely closed. The oven will not generate microwaves if the door is not fully latched.

2. Open and close the door firmly three times to ensure the latch mechanism is properly engaged.

3. Make sure you have set a cooking time and power level, and then pressed the START button.

4. Check that you are not in Timer mode, which does not cook.

5. If the oven continues to run without heating, there is likely an issue with an internal high-voltage component, such as the magnetron or transformer. For your safety, this requires diagnosis and repair by a qualified service technician.

If the turntable is not working, follow these steps:

1. Check that the turntable feature is turned on. Press the TURNTABLE ON/OFF button to ensure it is active.

2. Remove the glass tray and the rotating ring assembly. Clean them and the oven floor to remove any food debris that might be obstructing movement.

3. Ensure the glass tray is properly seated on the rotating ring and that the center of the tray is correctly aligned with the turntable motor shaft.

4. If the oven lamp turns on when a cooking cycle starts but the turntable still does not move, the turntable motor may be faulty and require professional service.

If your LG LMVM2033SW starts operating on its own without you pressing the START key, this indicates a potentially serious fault. For your safety, please do the following:

1. Immediately stop using the oven and unplug it from the power outlet.

2. This condition is often caused by a short in the control panel or a failure in the door interlock switch system.

3. Do not attempt to use the oven. This issue requires professional service from a qualified technician to be resolved safely.

Your LG LMVM2033SW is designed with multiple safety features to contain microwave energy. However, you should be aware of the following:

• If the oven operates with the door open, stop using it immediately and unplug it. This is a serious safety hazard.

• Do not use the oven if you notice any physical damage that could compromise the door seal, such as:

– The door does not close firmly.

– A broken hinge or latch.

– A damaged door seal.

– A door that is bent, warped, or misaligned.

• Always keep the door, its seal, and the mating oven surfaces clean and free of debris.

• Any service or checks for microwave leakage must be performed by a qualified service professional using specialized equipment.
