Checking items such as the switch in the circuit box that powers the cooktop, debris on the cooktop and the size of the cookware are three common steps in troubleshooting the most frequent issues that affect performance. Going through this troubleshooting process can save the expense of a service call.
If the induction cooker does not operate at all, it is helpful to go to the circuit box and check the switch or fuse. Replacing the fuse or resetting the breaker should solve the problem, but if it keeps recurring, a professional electrician may need to address the circuit overload. If the power is not the problem, the unit may need replacing.
In some cases, the cooktop shuts off during the middle of the cooking process. Some models are programmed to turn off automatically after a given amount of time, and if that is the case, this time appears in the instruction manual. Another case could be high temperatures sensed inside the unit. Debris can block vent holes for the cooktop, elevating interior temperatures. Cleaning those holes can solve the problem.
If the element fails to heat the food, the cookware may not have a large enough bottom to activate the cooking zone. If the cookware does not have magnetic material or is warped, it may not activate the cooktop. The cookware must be centered over the surface for the heat to transfer properly.
