LG Microwave Oven, power level adjustment? - LG Microwave Ovens

If your LG Solardome microwave oven is overheating a melamine plate within 30 seconds, there could be a few potential issues at play:

1. Power Settings: Check to see if the power settings on your microwave are too high. If it's set to a high power level, it can cause certain materials, like melamine, to overheat quickly. Try reducing the power level and see if that helps.
2. Plate Material: Melamine plates are not suitable for use in microwave ovens as they can overheat and potentially release harmful chemicals into your food. It's recommended to use microwave-safe dishes made of glass, ceramic, or microwave-safe plastic.
3. Microwave Performance: If the microwave is consistently overheating items within such a short time frame, it might indicate a malfunction. In this case, it's best to contact LG customer support or a certified technician to inspect and repair the microwave.
4. Placement and Usage: Ensure that the plate is placed centrally on the turntable and not touching the sides of the microwave. Also, avoid using the microwave for extended periods without interruption, as this can cause overheating.
5. Testing with Different Materials: Try using a microwave-safe ceramic or glass plate to see if the issue persists. If other materials heat up quickly as well, it could indicate a problem with the microwave itself.

What is it that you are losing ? You can set the power level by using the marked touchpads on the touchpanel, much like setting the volume on a TV. If you do not change the power setting and it is taking a long time to heat things or intermittently fails to, that is usually a sign that the Magnetron has reached its use by date and needs to be replaced. Not always an economical proposition unfortunately as spare parts are often exorbitantly priced.
Before removing the cover of the oven in attempt to carry out any maintenance such as replacing the Oven cavity lamp, make sure the oven is disconnected from the power point ! The voltages in a microwave oven ARE LETHAL !

As you didn't specify any specific model, one of the Samsung models uses this scheme to change power levels.

You begin by pressing the "Microwave" button once. Pressing it again will display different power levels, from low to high.

Place the items inside the unit and close the door. Set the cook time, then press the "Power Level" button. When the display asks for input, press "5" for 50% power. Then press START.

There are no heat levels on a microwave oven, only power levels. I am not aware of any method of checking the power level except to boil water. Boil water at each level and time how long it takes to boil. The lower the power, the longer it should take. If there are no differences in the time, the oven is not functioning as expexted.

There is a built in triac switching semiconductor, when it fails the high setting is lost, it switches the power levels through incriments from low to high.

I see by looking at the owner's manual there is an option to set power level from 0% to 100%, maybe that is set too low (see page 14 of manual). If don't have manual for that model (LMVM2277ST), can get from this web page (look near bottom of page and click words "owner's manual" that are underlined) :

Microwave Oven Basic Troubleshooting Tips

If the microwave functions normally while cooking everything else, but is only burning popcorn, there is no component problem that will cause this. You cannot adjust or replace any internal component to make it not burn popcorn. All power levels and program options are contolled by the consumer at the control panel. Refer to your owner;s manual for their recommendations.

If the oven is equipped with a popcorn feature button, it is programmed for a recommended power level and time. This is an ESTIMATED program feature. The manufacturers of both the oven and the popcorn will also give directions that tell you to turn the oven off when the popping slows to about a pop every 2 seconds. Failure to do so can result in burning.

If the microwave does not come with a popcorn feature button, the manufacturers of the popcorn have directions on the outside of the box that tell you what POWER LEVEL and TIME to set the oven on for the desired result. Again, the you still have to listen as the bag pops to ensure it does not burn.

In addition, on some microwave ovens, there is a feature that allows you to select the SIZE of the popcorn bag. Some popcorn manufacturers have smaller snack size bags that don't take as long to pop. You have to select the appropriate size to get the correct program option.

In any case, you never are to place popcorn in a microwave oven and walk away from it. All these program features are ESTIMATIONS based on manufacturers testing and recommendations for the best results. All microwave ovens are different and operate at different power levels. Your best judge is to listen as it pops.

I hope this helps you.

Press "Power" until you get to the level you want. Then enter the # of minutes on the keypad (CANNOT use express cook times.) An alternating runnig hum will let you know the setting is working.
