2 electricity without reaction, check the power supply circuit. Remove 250V/8A fuse, from the appearance of seemingly not fuse, multimeter ohm retaining measure, resistance is infinite, need to be replaced. Select "fire"2QYservice manual download site
Electricity, still not working. Shutdown check, door interlock switch LXW-l0Bl6 (0.3A/250V) from the positioning groove, and one end plug sheet is broken, use a string connected test machine, fan and the tray rotating lights, but not heating.2QYservice manual download site
30000 meter measuring high voltage diode TS01 (14512), high voltage capacitor CH85 (O.80 μ F/2lOOAC) normal. Through measuring voltage transformer primary voltage free Y600STC220V/50Uz. Detection of a timing switch circuit wiring are as follows2QYservice manual download site
The timing switch back wiring column from the left to the right function is: the fan motor, the power supply line, connected to the magnetron, MT, the lighting, the space, and the tray motor.2QYservice manual download site
Check the timer posts have electricity, but the primary winding voltage transformer is still without electricity, judge between the terminal and the terminal plug bad contact, to clean the fastening, test machine, each function.2QYservice manual download site
Summary: This machine to replace the fuse, 250V/8A, LXW1-10B16 door switch, a timing switch terminals to oxidation fastening.2QYservice manual download site
