[. . . ] Com manuals search engine PRECAUTIONS TO BE OBSERVED BEFORE AND DURING SERVICING TO AVOID POSSIBLE EXPOSURE TO EXCESSIVE MICROWAVE ENERGY (a) Do not operate or allow the oven to be operated with the door open. (b) Make the following safety checks on all ovens to be serviced before activating the magnetron or other microwave source, and make repairs as necessary: (1) Interlock operation, (2) Proper door closing, (3) Seal and sealing surfaces (arcing, wear, and other damage), (4) Damage to or loosening of hinges and latches, (5) Evidence of dropping or abuse. (c) Before turning on microwave power for any service test or inspection within the microwave generating compartments, check the magnetron, wave guide or transmission line, and cavity for proper alignment, integrity, and connections. (d) Any defective or misadjusted components in the interlock, monitor, door seal, and microwave generation and transmission systems shall be repaired, replaced, or adjusted by procedures described in this manual before the oven is released to the owner. [. . . ] (2) To reduce gap located on part ‘B’ • Loosen two screws on the stopper hinge under, and then push the door to contact the door seal to the oven front surface. (3) To reduce gap located on part ‘C’ • Loosen the screw on the interlock switch assembly located the top of the oven body. €¢ Draw the interlock switch assembly inward as possible to engage with the hook on the door bottom. (4) To reduce gap located on part ‘D’ • Loosen the screw on the interlock switch assembly located the bottom of the oven body. NOTE :A small gap may be acceptable if the microwave leakage does not exceed 4mW/cm2. 7 ABS SG-076D SG-175 Q'TY 1 1 1 3 1 1 1 REMARK (1) Remove the screw which secure the control panel, push up two snap fits and draw forward the control panel assembly. (2) Remove three screws which secure the PCB assembly to control panel. (3) Disconnect membrane tail from the connector of the PCB assembly. (4) Remove the PCB from the control panel. (5) Remove the membrane, lever door open, spring button and button door open from the control panel. (6) Reverse the above steps for reassembly. 1) Remove the screw which secure the grounding ring terminal of the H. 3) Reverse the above steps for reassembly. 1) Remove the screw which secure the magnetron. 3) Reverse the above steps for reassembly. NOTE : Never install the magnetron without the metallic gasket plate which is packed with each magnetron to prevent microwave leakage. Whenever repair work is carried out on magnetron, check the microwave leakage. It shall not exceed 4mW/cm2 for a fully assembled oven with door normally closed. 2) Remove the noise filter from the wind guide. 3) Remove the screw which secure the wind guide assembly. 4) Draw forward the wind guide assembly. 6) Remove two screws which secure the motor shaded pole. [. . . ] A normal diode’s resistance will be infinite in one direction and several hundred KΩin the other direction. Magnetron For complete magnetron diagnosis, refer to “Measurement of the Microwave Power Output”. (1) Isolate magnetron from the circuit by disconnecting the leads. (2) A continuity check across magnetron filament terminals should indicate 0. [. . . ]
