Common Issues with Induction Cooktops
Table of contents
Induction cooktops are convenient, functional, and safe appliances. Their high reliability is ensured not only by their unique operating principle but also by the use of modern technical solutions. However, like any other household appliance, induction cooktops can occasionally experience issues of varying complexity. Most of the time, these issues arise due to improper use of the appliance. While some problems can be fixed on your own, the majority require professional intervention.
Common Issues with Induction Cooktops
Induction cooktops are reliable appliances, but they do require careful handling and regular maintenance. A common problem with induction cooktops is the burnout of high-voltage transistors, damage to the conductive tracks on the module, destruction of electronic components due to moisture exposure, and mechanical damage to the appliance.
Device Not Turning On
If your induction cooktop won’t turn on, first check the outlet for power. Then inspect the plug and power cord for any visible or internal damage, replacing them if necessary. If power is flowing correctly, check the fuse and main switch. Next, examine the wiring between the control unit, power board, and touch panel. Replace any faulty module, and if that doesn’t work, the coil block might need replacement. If an error code appears on the screen, try unplugging the cooktop for 30 seconds and then restarting it. If the error persists, the control board likely needs replacement.
Touch Panel Not Responding
Induction cooktops use touch controls. If the touch panel isn’t responding, try rebooting the device by unplugging it for 1-2 minutes. Sometimes, the issue is simply the child lock being activated—turn it off to restore functionality. A dirty panel can also cause unresponsiveness, so clean it thoroughly. If these steps don’t help, it’s time to call a professional.
Poor Heating of Cookware
Insufficient heating of cookware can be caused by improper positioning. If the cookware is not centered on the burner or has a smaller diameter than the burner itself, the heating will not be evenly distributed across the bottom. A similar issue may occur if the cookware does not sit flush against the glass-ceramic surface. Poor heating can also result from inadequate power supply to the appliance. To diagnose this issue, unplug the power cord and carefully inspect it for any damage.
Cooktop Flashing
When the induction coil overheats, the control unit automatically reduces power, causing the power indicator to flash between the set and reduced levels. In this case, unplug the cooktop and check the coil's condition.
Timer and Other Options Not Working
If the cooktop timer malfunctions, turning off too early or late, it’s best to consult a service center. For residual heat indicator issues, check the temperature sensor with a software test; if that fails, the control unit may need replacement. If the LCD elements work partially or stay lit, inspect the connections between the control unit and touch panel or replace the connecting cable. Persistent issues might require control unit replacement.
The cooling fan in induction cooktops turns on periodically. If it runs constantly, it could be due to max heating power or high ambient temperature. If it doesn’t turn on, it may be because of low power settings. Test the fan with a diagnostic program, and if faulty, replace it.
One or More Burners Not Working
If one or more burners on your induction cooktop aren’t working, first ensure you're using the correct cookware—made of steel, cast iron, or with a ferromagnetic base. If the cookware is correct, check the burner’s temperature sensor using test programs. Also, ensure the induction module is tightly attached to the glass-ceramic panel, adjusting the pressure springs if needed.
If the left pair of burners isn’t working, inspect the connections between the coils, control unit, and power board. Faulty wiring may indicate a control unit issue, which usually requires replacement. For the right pair, check the terminal box contacts and replace any blown fuses in the coil block.
A high-power burner might not turn on if others are in use due to automatic safety features preventing overheating. It will activate once the other burners cool down.
Should You Repair It Yourself?
Repairing an induction cooktop on your own is not advisable. It requires engineering knowledge, the right tools, and components. Disassembling the device without understanding its construction can lead to further damage, making reassembly difficult. Additionally, since it’s an electrical appliance, strict safety protocols must be followed to avoid electric shock. A poorly done repair not only endangers the cooktop but also the safety of everyone in your home.
