H on the induction cooker indicates that the temperature of the induction cooker is still relatively high, indicating that the induction cooker is in standby state after use. The display of H code is to remind the operator not to power off immediately, and the induction cooker needs to dissipate heat after working. If the power is cut off immediately at this time, the induction cooker cannot dissipate heat normally. When the induction cooker is used up, H indicates that the temperature is high, so don't turn off the power. When the heat dissipation is completed and H disappears, you can turn off the power.
