电磁炉热力不正常故障维修（Maintenance of abnormal thermal malfunction of induction cooker） The electromagnetic oven heat is not normal maintenance of city entrance: Shenzhen - Dongguan - Guangzhou - Beijing - Shanghai with | set home Home market, laws and regulations, household electrical appliance enterprises, home appliances purchase Home appliance technology, maintenance skills, home appliance repair enterprises Home appliance technology: air conditioning technology, refrigerator technology, washing machine technology, disinfection cabinet technology, hood technology, TV technology, audio equipment technology, microwave technology, water heater technology Maintenance skills: air conditioning, refrigerators, washing machines, disinfecting cabinets, range hoods, TV sets, audio equipment, microwave ovens, electromagnetic ovens, water heaters Current position: home appliances online abnormal heating of electromagnetic oven maintenance article text Maintenance of abnormal thermal malfunction of induction cooker (1) the temperature rise of the gate is too high: the fault is mainly that the electromagnetic oven will stop heating after a period of work, and send out the alarm sound or the gate temperature fault code, and then automatically switch to standby. When checking, check that the fan is running properly. If not normal, check Q204, Q205, D262 and fan. Pay special attention to whether the air inlet and exhaust channel of the cabinet are unblocked, whether or not the door heat sink is attached to oil pollution. If the fan is functioning properly, check the gate drive circuit. Mainly to check whether the ZD201 leakage current is too large, Q4 and Q6 performance is normal (preferably replaced), and whether +18V is low. (2) the power supply circuit is poor in filtering: this fault shows that when the electromagnetic furnace works with the highest firepower, the intermittent pause will occur frequently if the power voltage of the city is slightly lower. This is because the use in lo
