Question:
Meaning and Solutions of Induction Cooker Fault Code H
Answer:
When the induction cooker displays the "H" code, it usually indicates that the device has detected that the panel temperature is too high, which is mostly related to the residual heat reminder or the activation of overheat protection
Common meanings
1. Residual Heat Warning: After heating stops, when the panel temperature remains above approximately 53°C, "H" will be displayed to remind you to be cautious of burns.
2. Overheat protection: When the internal temperature is too high during operation (such as poor heat dissipation), the device automatically stops heating and displays "H" for protection.
The main reason
1. Heat dissipation issues: blocked ventilation openings, non-rotating fans, or internal dust accumulation affect heat dissipation.
2. Improper use: long-term overloading (such as continuous use at maximum power), excessively high ambient temperature, or incompatible cookware.
3. Component anomaly: Temperature sensor malfunction or issues with the relevant control circuit.
When users encounter the "H" code
First, determine the scenario:
· If the panel still feels hot to the touch right after heating has just stopped, this is usually a normal indication of residual heat, which is a normal phenomenon. It reminds you that the panel is still hot, so please do not touch it directly with your hands. Wait for 'H' to go out before cleaning or moving the induction cooker.
· If it suddenly stops during operation and displays "H", it is an overheat alarm.
· Steps for handling overheat alarms:
1. Immediately turn off the power and unplug the cord: This will completely stop the induction cooker from operating.
2. Let it stand and cool: Move it to a well-ventilated area and allow it to cool naturally for at least 30 minutes.
3. Check and clean:
· Ensure that there are no obstructions in the ventilation openings at the bottom and sides of the induction cooker.
· Observe whether the fan is rotating normally (if there is a visible gap). If the fan does not rotate, it can basically be determined that there is a problem with the fan.
· Clean the panel and body, removing oil stains and dust.
4. Re-energize and test: After cooling, re-plug the device and turn it on. Use a suitable cookware with a small amount of water and test the machine at medium to low power.
· If it returns to normal, remind the user to pay attention to the usage method and heat dissipation environment.
· If the alarm goes off again or the fan still doesn't turn, you need to contact a professional maintenance technician for inspection and repair.
How to prevent the "overheating" problem
· Ensure heat dissipation: When in use, ensure there is sufficient space around the induction cooker, especially at the bottom, for heat dissipation.
· Correctly select cookware: Use special cookware with a flat bottom and good magnetic conductivity.
· Avoid long-term extreme use: When long-term cooking is required, medium to low power can be appropriately used in the middle.
· Keep Clean: Regularly clean the panel and body to prevent grease from clogging the air duct.
