Did You Know?

1. In the early 1900s, the concept of induction heating was developed by Dr. William Stanley, who used it to heat metals for industrial purposes.
2. Induction cookers work by creating a magnetic field that heats up the cookware directly, making them more energy-efficient and faster than traditional cooktops.
3. One of the common reasons for an induction cooker not heating is a faulty or misplaced magnetic field sensor, which may need to be recalibrated or replaced.
4. The phenomenon of “eddy currents” is responsible for the heat generation in an induction cooker. When alternating current passes through the copper coils beneath the cooktop, the eddy currents inside the ferromagnetic cookware create heat as a result of resistance.
5. While induction cookers offer many advantages, they have limitations too. For instance, they only work with cookware made of ferrous materials such as cast iron or stainless steel. Non-magnetic cookware like copper, aluminum, or glass cannot be used on induction cookers without using an induction interface disc.

Inspecting The Junction Box And Copper Coil

When troubleshooting a non-heating induction cooker, it’s crucial to begin by inspecting the junction box. Ensure that the junction box is properly covered and securely fastened to prevent any potential electrical issues. Next, examine the copper coil and wiring beneath the induction stove. Over time, these components may suffer from damage or wear, leading to cooker malfunction.
