Used equipment sales microwave hurried to the store looking for high-voltage capacitors and fuses. No first wife . Look capacitance tolerances allowed , signs of ± 3%. Accordingly , the purchase of the two capacities of 1.1μF and 1.09μF capacitor. Came back with a digital capacitance / inductance meter (DM-6243L) measurement, no errors. 1.09μF/2100WVAC decided capacitance test. Careful circuit installed , check and correct cover housing ( anti- microwave radiation ) , power , display properly. Ready for a cup of cold water , placed in the center of the microwave oven , press the "Start " button , the turntable rotates, the display remains lit , indicating that everything is normal. Look ammeter , 5A table refers to the extreme . After a few seconds, press the " pause" button , open the door to see the water temperature , water vapor around the glass has been covered up .JgCservice manual download site

High voltage capacitors on the secondary market , there are many varieties: pressure is 2100V, while never capacity ranging from 0.85-1.1μF . I believe that the capacity of the capacitor size and output power related to the case that the same transformer output voltage , large capacitance can be slightly higher output voltage . Therefore , the output will be slightly larger magnetron power . As for why to be accurate to two decimal places , may be considering the consistency of manufactured products output power requirements . In this regard , I have something to eat impervious . Do not buy the same type of fuse affect the use of estimates is an issue. Capacity due to corrosion of the original fuse reasons not clear to see , like 8A. Now use ordinary 10A fuse , could affect the life of a large current impact fuse . High voltage circuit microwave are similar. The difference is that the control circuit of the microwave oven . But in most cases , the manufacturers do not provide control circuit.JgCservice manual download site
