Induction cooktops heat through magnetic energy. The"----"message usually appears for one of the following reasons:

1. No cookware is placed on the cooktop. The unit must detect a pot or pan before it can begin heating.

2. The cookware is not compatible with induction cooktop. Please use a cookware with a magnetic base. You can test your cookware using the magnet included in the package, if the magnet sticks to the bottom, the cookware is induction-compatible.

If none of the above applies and the unit still does not operate properly, please contact us through the"Other Question or Support?"section below. Provide your name, order number, shipping address, and phone number, and we will promptly arrange a replacement unit for you.

This is normal. What may appear as "inaccurate temperature control" is actually a built-in slight delay in how the internal processor regulates temperature, and it is part of the product’s design.

The temperature sensor is mounted under the glass top, and the control system adjusts power output based on feedback from this sensor. Because induction cooktops heat the cookware ITSELF through a magnetic field, the sensor measures heat transferred through the cookware rather than the temperature of the food directly. Since heat must travel from the cookware to the glass before being detected, a small delay or difference between the displayed reading and the food temperature is expected.

In addition, temperature readings may vary depending on cookware material, ambient room temperature, the amount and type of food, and the timing of checking the food temperature.

In TEMP mode, the cooktop is designed for steady, controlled heating rather than rapid temperature increases. If faster heating is needed, we recommend using HEAT mode.

Induction cooktops work differently from gas or electric stoves, they heat the cookware ITSELF through a magnetic field. Heating performance can vary depending on how the unit is used and the cookware selected.

1. Choosing the right heating mode is important.
For faster heating, we recommend using HEAT mode. It is not recommended to start heating in TEMP mode.
We recommend to use HEAT mode first to bring food or water to a boil or the desired level, then switch to TEMP mode to maintain the temperature.

HEAT Mode uses power levels to heat quickly and is ideal for boiling water, and other fast-cooking tasks.
TEMP Mode adjusts power based on the temperature sensor to maintain a set temperature. It heats more slowly but provides more precise temperature control.

2. Cookware has a significant impact on heating speed.
Heating performance can vary depending on the cookware’s magnetic composition, effective magnetic contact area, material, and thickness.

Some aluminum cookwares with a bonded magnetic base may be detected by the cooktop, but the effective magnetic area is relatively small, which can prevent the cooktop from fully utilizing its heating capability and result in slower heating.

For best results, we recommend using fully magnetic cookware with a medium to heavy-gauge base. You can use the magnet included in the package to test whether the bottom of your cookware is magnetic.

This is normal and intentional, and it is part of how induction cooktops are designed to heat quickly while preventing overheating. Induction cooktops regulate heat output through a controlled heating cycle rather than applying continuous power.

The heating cycle is managed by the cooktop’s internal control chip, which continuously monitors temperature and automatically adjusts the heating output based on the selected setting, the type of cookware, and the temperature detected.

In TEMP Mode:
The temperature sensor is mounted under the glass top. When the base of cookware’s temperature approaches the set value, the cooktop cycles the heating to maintain the target temperature within the designed range. This is especially effective when cooking smaller portions, as it helps prevent overheating or burning.

The cooling fan is designed to regulate the internal temperature of the induction cooktop. You may hear the fan while the unit is operating, and after the cooktop is turned off, the fan may continue to run for about 1 minute, during which the display may still show "H" or "L".

This after-cooling process is completely normal and helps protect the internal electronic components, ensuring safe and reliable operation. Once the internal temperature drops to a safe level, the fan will automatically shut off.

This is a normal part of the induction heating process. Induction cooktops heat the cookware ITSELF through magnetic induction, not the surface of the cooktop. At the beginning of heating, energy is more concentrated in the center of the pan, so you may initially see a smaller, more defined bubble ring in the middle. This is simply an early-stage energy concentration effect and does not mean the coil is smaller or that only that area is being heated.

As heating continues, the heat gradually spreads outward across the bottom of the cookware. The 8-inch coil is designed to provide consistent, even heating across the entire base of the pan, resulting in stable and uniform cooking performance over time.

Heating performance is also influenced by the size and material of the cookware. If the effective magnetic contact area on the bottom of the pan is smaller, the active heating zone may appear smaller at first. Only when the magnetic surface area is large enough can the full 8-inch induction field be fully engaged.

In addition, induction cooktops only work with magnetic metals, such as cast iron or magnetic stainless steel. If the cookware has weak magnetism, the magnetic field may not be fully activated, making the heating area appear smaller.

In actual cooking, the size of the visible bubble ring does not affect overall performance or heating speed. For best results, we recommend using flat-bottom cookware with strong magnetic properties. You can also use the magnet included in the package to test whether your cookware is induction-compatible.

HEAT mode and TEMP mode operate independently and are designed for different cooking needs.

HEAT mode is intended for fast heating, while TEMP mode focuses on maintaining a steady temperature. As a result, TEMP mode may take longer to reach the target temperature compared to HEAT mode.

HEAT mode provides multiple power levels to suit different cooking tasks—the higher the power level, the faster the heating.

For example: Model 103020-A
HEAT mode power range: 200W–1800W

Low power (200–800W): ideal for warming and simmering
Medium power (1000–1400W): suitable for pan-frying
High power (1600–1800W): ideal for fast boiling and preheating
For power settings on other models, please refer to the Quick Reference Guide.

TEMP mode allows you to set a target temperature between 120°F and 460°F. The cooktop automatically adjusts power output to maintain the selected temperature as closely as possible. This mode is suitable for frying, sous-vide cooking and keeping food warm.

Note: The ability to reach and maintain the set temperature may be affected by cookware material, food volume, and ambient temperature.

This induction cooktop works with cookware that has a magnetic base. You can easily test your cookware using the small magnet included in the package, if the magnet sticks to the bottom of the cookware, it is induction-compatible. In addition, the cookware should have a flat contact surface with a diameter greater than 4.75 inches (12 cm).

Examples of compatible cookware:
• Stainless steel with a magnetic base
• Aluminum cookware with a magnetic base
• Enameled porcelain cast iron
• Cast iron
• Carbon steel

Examples of non-compatible cookware:

• Aluminum cookware without a magnetic base
• Glass cookware
• Copper cookware
• Ceramic cookware

This is normal. The noise you hear during use usually comes from the cookware, not from a malfunction of the induction cooktop.

Unlike gas or electric stoves, an induction cooktop heats the cookware ITSELF through magnetic induction. When the cooktop is operating, the bottom of the cookware heats up very quickly under the magnetic field.

Many cookware items marketed as"induction-compatible"do not have a solid, single-material base. Instead, the bottom is often made by bonding multiple materials together, for example, aluminum cookware with a magnetic steel plate attached to the bottom. Small gaps or differences between these materials can cause slight vibration and resonance during rapid heating, which may produce a buzzing or sizzling sound. This effect is more noticeable at higher power levels.

Cookware that is more likely to produce noise includes: Aluminum cookware with a bonded magnetic base, Cookware with different materials for the body and handle and Thin-bottom or layered-base cookware.

These sounds are a normal physical result of resonance during induction heating and do not affect the cooktop’s performance or safety.

Generally, the cookware made from a single, solid material, such as cast iron. These cookware types are more stable, quieter during heating, and provide more even results.We recommend preheating the cookware before cooking to achieve better results.

This is a normal electrical phenomenon. Induction cooktops are high-power appliances and contain internal capacitive components. When the plug is connected to the power supply, these components may charge rapidly, creating a very brief current surge that can sometimes appear as a small visible spark.

This type of spark occurs only for a brief moment, does not continue, and does not affect the product’s normal operation, performance, or safety. The unit complies with applicable electrical safety standards and is certified by UL, ETL, and NSF, ensuring safe and reliable operation under normal use conditions.

Please note that this phenomenon is not related to whether the unit uses a two-prong or a three-prong (grounded) plug.

For best results, we recommend plugging in or unplugging the unit only when it is powered off and ensuring that the outlet provides a secure, firm connection.
