According to the fault analysis may be auto-reset circuit of the control circuit is faulty, if the correlation circuit drawings.Lncservice manual download site
IC01 by a microprocessor reset circuit automatically reset terminal @ pin, Q16, R32, R44, R51, R52, ZD3, C3 composition, so that 33 foot plus high finish IC01 reset.Lncservice manual download site
Boot, 5V power measurement is normal, and then measuring instantaneous power after IC01 33 feet is still 0V (normal should be high), indicating that the microprocessor IC01 not automatically reset.Lncservice manual download site
Power, reset circuit each component inspection and found that the ec Q16 has a very open, resulting in automatic reset circuit malfunction caused the failure. Replace Q16. Power test machine, the normal heating microwave troubleshooting.Lncservice manual download site
