LG LMC2075ST user manual

Inverter defrost is a feature found in some LG LMC2075ST models. It is a technology that helps to improve the defrosting process of the microwave.
Traditional microwaves use a simple timer-based defrosting method, where the power is turned on and off at regular intervals during the defrost cycle. This can often result in uneven defrosting, with some parts of the food being overcooked while others remain frozen.
Inverter defrost technology works differently by adjusting the power level of the microwave in real-time during the defrost cycle. It utilizes sensors to detect the temperature and consistency of the food, and then modulates the power output accordingly. This allows for a more consistent and even defrosting process.
Overall, inverter defrost helps to ensure that the food is defrosted properly, without any overcooking or undercooking. It can be particularly useful for thawing delicate or unevenly shaped items, such as meat or poultry.

There could be several reasons why your LG Smart Inverter microwave is not heating:
1. Faulty Magnetron: The magnetron is responsible for producing heat to cook the food. If this component fails, your microwave will not be able to heat the food.
2. Damaged Diode: The high voltage diode renders conjoint microwave power from the magnetron to the cooking chamber. If the diode burns out, the microwave will not heat.
3. Faulty Door Switch: The door switch indicates whether the door is closed correctly. If it's faulty, the microwave might not be able to start the heating process.
4. Defective Control Board: The control board controls the various components of your microwave. If it fails or has power issues, the microwave might not heat even though the display and buttons are functioning normally.
5. Failed Capacitor: The capacitor stores electricity and releases it to the magnetron for creating heat. If it is failed, it might not supply enough power thus leading to no heat production.
6. Transformers: Transformers are used to step up the power for heating elements.
This issue requires a professional's attention. If your microwave is still under warranty, contact LG customer service. If not, you might want to reach out to a local appliance repair expert. Make sure to unplug your microwave before attempting any fixes.

There could be several reasons why your LG microwave is not working. Here are a few common troubleshooting steps you can try:
1. Check the power source: Make sure the microwave is properly plugged into a working power outlet and that the outlet itself is functioning. You can test this by plugging in another device or appliance.
2. Reset the circuit breaker: If the microwave is not receiving power, check the circuit breaker or fuse box to ensure that the circuit is not tripped or the fuse is not blown. Reset the breaker or replace the fuse if necessary.
3. Check the display panel: If the display panel is not turning on or showing any signs of life, it could indicate a problem with the control board or power supply. In this case, it may require professional assistance to repair or replace the faulty components.
4. Reset the microwave: Some microwaves have a reset button that you can press to reboot the system. Refer to the user manual of your LG microwave to locate and reset the unit.
5. Door interlock switch: The microwave will not start if the door interlock switch is not functioning properly. Check that the door is closed securely and that the switch is not damaged or misaligned.
6. Contact LG customer support: If none of the above steps resolves the issue, it is recommended to reach out to LG customer support or schedule a service appointment for further diagnosis and repair.
Remember, microwaves contain high voltage and can be dangerous to work on without proper knowledge and precautions. If you are unsure or uncomfortable troubleshooting the issue yourself, seek professional assistance.
