Question:
Electric Ceramic Cooker Displays H Code and Solutions
Answer:
When the induction cooktop displays the code "H", it usually represents "overtemperature" or "overheat protection".
1. Temporary overheating during normal use (most common)
· Reason: When you use the induction cooker at maximum power (such as stir-frying at full heat or boiling water) for an extended period, the substantial heat generated by the induction cooker may temporarily exceed the capacity of the heat dissipation system, triggering protection.
· Solution:
· Pause use and allow natural cooling: Immediately turn off the power and let the induction cooktop cool quietly for 20-30 minutes.
· Restart: After it has completely cooled down, turn it on again. Usually, the "H" code will disappear, and it can be used normally.
· Follow-up usage suggestions: Avoid using the highest power setting continuously for an extended period. If long-term cooking is required, alternate between medium-high and high power settings to give the cooktop a "breathing" opportunity.
2. The heat dissipation and ventilation holes are blocked
· Reason: The bottom or side of the induction cooktop is designed with ventilation holes, and there is a cooling fan inside. If these ventilation holes are blocked by kitchen grease and dust, or if the cooktop is placed in a sealed cabinet or too close to the wall, it will cause heat to fail to dissipate and accumulate inside.
· Solution:
· Cleaning after power outage: Ensure the power is completely disconnected and the cooktop has cooled down, then use a soft brush or vacuum cleaner to clean the ventilation holes at the bottom.
· Check the cooling fan: Listen carefully to see if the fan rotates normally after the device is powered on. If the fan does not rotate or rotates weakly, it needs to be reported for repair.
· Ensure the placement environment: Place the induction cooktop in a well-ventilated and open area, leaving sufficient space (recommended at least 10-15 cm) at the back, top, and sides.
3. Used inappropriate cookware
· Reason:
· Uneven pot bottom: If the pot bottom is convex or uneven, it will cause only partial contact between the cookware and the panel. Heat cannot be effectively absorbed by the cookware and accumulates in large amounts in a local area of the panel, causing the temperature at that point to rise sharply and triggering over-temperature protection.
· The cookware is too small: Using cookware with a diameter much smaller than the heating area of the burner core will also cause heat to concentrate and fail to dissipate.
· Solution:
· Be sure to use a frying pan, and the diameter of the pan bottom should roughly match the marked circle on the burner.
4. Temperature sensor or control board malfunction
· Reason: A malfunction of the temperature sensor itself or a fault in the relevant circuit on the main control board may cause it to continuously give false high-temperature signals.
· Solution:
· Initial troubleshooting: If all the above situations have been ruled out (i.e., good ventilation, use of a frying pan, and not long-term high-power operation), but the device displays "H" as soon as it is turned on or when using very low power, then it is most likely a hardware failure.
· Contact after-sales repair: Please immediately stop using the product and contact the brand's official after-sales services or professional repair personnel. This is a circuit issue, and self-disassembly and repair pose safety risks and may cause greater damage.
5. There are foreign objects or liquids on the panel
· Reason: If food spills or flammable materials such as plastic or paper towels are placed on the panel while it still has residual heat, they will carbonize due to high temperature and adhere to the panel. These carbonized layers will form an insulating layer, affecting temperature measurement and potentially causing local overheating.
· Solution:
· Ensure the panel is clean: After the cooktop has completely cooled down, thoroughly clean the panel to ensure no foreign objects remain.
