Resumen del manual
95mm(3.5in.). 3. Place it at the center of the tray and set it in a cavity. 4. Close the door and operate the oven. 5. Measure the leakage by using Microwave Energy Survey Meter with dual ranges, set to 2450MHz. 1) Measured radiation leakage must not exceed the value prescribed below. Leakage for a fully assembled oven with door normally closed must be less than 4mW/cm2. 2) When measuring the leakage, always use the 5cm(2in.) space cone with probe. Hold the probe perpendicular to the cabinet and door. Place the space cone of the probe on the door, cabinet, door seem, door viewing screen, the exhaust air vents and the suction air vents. 3) Measuring should be in a counter-clockwise direction at a rate of 1 in./sec. If the leakage of the cabinet door seem is unknown, move the probe more slowly. 4) When measuring near a corner of the door, keep the probe perpendicular to the areas making sure the probe end at the base of the cone does not get closer than 2 in. from any metal. If it does not, erroneous reading may result. 17 3. COMPONENT TEST PROCEDURE • High voltage is present at the high voltage terminal of the high voltage transformer during any cooking cycle. • It is neither necessary nor advisable to attempt measurement of the high voltage. • Before touching any oven components or wiring, always unplug the oven from its power source and discharge the capacitor. 1. High voltage transformer (1) Remove connections from the transformer terminals and check continuity. (2) Normal readings should be as follows: Secondary winding ...................Approx. 110.±10% Filament winding....................................Approx. 0. Primary winding .....................................Approx. 1. 2. High voltage capacitor (1) Check continuity of capacitor with meter on the highest OHM scale. (2) A normal capacitor will show continuity for a short time, and then indicate 10M. once the capacitor is charged. (3) A shorted capacitor will show continuous continuity. (4) An open capacitor will show constant 10M.. (5) Resistance between each terminal and chassis should be infinite. 3. High voltage diode (1) Isolate the diode from the circuit by disconnecting the leads. (2) With the ohmmeter set on the highest resistance scale measure the resistance across the diode terminals. Reverse the meter leads and again observe the resistance reading. Meter with 6V, 9V or higher voltage batteries should be used to check the front-back resistance of the diode, otherwise an infinite resistance may be read in both directions. A normal diode’s resistance will be infinite in one direction and several hundred K. in the other direction. 4. Magnetron For complete magnetron diagnosis, refer to “Measurement of the Microwave Power Output”. Continuity checks can only indicate and open filament or a shorted magnetron. To diagnose for an open filament or a shorted magnetron. (1) Isolate magnetron from the circuit by disconnecting the leads. (2) A continuity check across magnetron filament terminals should indicate 0.1. or less. (3) A continuity check between each filament terminal and magnetron case should read open. 5. Fuse If the fuse in the primary and monitor switch circuit is blown when the door is opened, check the primary and monitor switch before replacing the blown fuse. In case the fuse is blown by an improper switch operation, replace the defective switch and fuse at the same time. Replace just the fuse if the switches operate normally. 18 WIRING DIAGRAM 19 20 EXPLODED VIEW AND PARTS LIST 1. DOOR ASSEMBLY Refer to Disassembly and assembly. 2.
