[LG electric range] Heating power is weak

Is your induction or highlight burner too weak? Did it stop operating while cooking?

Causes and Symptoms

• Cookware not suitable for an induction range was used.
• Cookware that does not match the burner size was used.
• The overheating prevention system was activated so the induction stopped working.
• The highlight stopped operating to maintain the temperature of the cooktop.

Since induction heats up cookware directly by creating a magnetic field from the coil installed under the burner, magnetic cookware should be used to ensure proper heating.
In addition, the overheating prevention system in the induction automatically stops the burner operation to prevent accidents if the cookware suddenly becomes hot or the internal temperature of induction rises while cooking on the large burner.
On the other hand, highlight heats up cookware with the heat from the cooktop, so it turns the heat wire off and on to adjust the amount of heat.
Therefore, even when it stops operating, it keeps the heat and the temperature is maintained.

Try this

Does the burner not operate or is the cookware not heated well when using the induction?

➔ Use induction-compatible cookware.

If induction-compatible cookware is not used, [U] will be displayed and the burner will not operate properly.
Use induction-compatible cookware with an IH or coil symbol at the bottom or an appropriate cookware according to the following information.
If cookware that worked fine before is not heating, it may be cracked or there may be a lot of foreign objects on its bottom surface, so check it.
If you have purchased new cookware, it is better to check first if it works well before cooking.

How to check your cookware for induction compatibility

Move left or right to check the contents.

If only part of the bottom of cookware is magnetic, the induction may not work properly even if it has an IH symbol.

Did you use cookware that doesn’t match the burner size of the highlight?

➔ Use cookware with a flat bottom surface that matches the burner size.

If you use cookware with a bottom surface smaller than the burner, the heat generated in the red part of the burner exposes to air may escape and the heating power may diminish.
Also, if you use cookware with a bottom surface larger than the burner, the heating speed may become slower in comparison to cookware with a bottom surface of proper size.
Therefore, use cookware with a proper bottom surface size.

Checking containers that match the burner size

Move left or right to check the contents.

Did the heating power diminish while using the large induction burner?

➔ The overheating prevention function was activated to prevent an accident, and this is a normal function.

To protect the parts inside the induction, the overheating prevention function is set to automatically turn off the burner when the temperature rises.
If the induction turns off and an [H] is displayed, turn the power off and on again.
Next, cook with low heating power to increase the temperature of the container slowly.
When using a frying pan, it is recommended that you place and use it on top of the burner, not removing it from the burner if possible.
The overheating prevention function is only set to the large burner, so if the burner frequently turns off even though you use the low heat, use the medium burner.

[Does the burner turn on and off repeatedly while using the highlight?]

➔ Highlights maintain the temperature of the cooktop without reducing the heat level even when the burner is turned off.

If the temperature of the cooktop rises after using the highlight for a long time, the burner is automatically turned off to maintain the heat.
When the heat is set to 9, the burner does not turn off for about 30 minutes to maintain the temperature.
However, if the temperature of the cooktop is already high, the burner may turn off even if you use level 9.
If you need to increase a heat level, use the dual function.
If you select the large burner and press the [Dual] button, the red light will turn on and the size of the large burner will increase.

Do you feel that the heat level of the highlight is lower than that of the induction?

➔ Due to a difference in the heating method, the actual heat level of the highlight is weaker than that of the induction, and the heat level varies by model.

The induction burner uses a magnetic field to directly heat the cookware with high efficiency, and the burner size is large, so the heat level is high.
However, the highlight heats up the cookware at a low efficiency by maintaining the cooktop at a constant temperature, and its burner size is also smaller than that of the induction, so its heat level is low.
Like this, the highlight and the induction have different heat level due to the different heating methods and burner size.
