4.3. Low voltage transformerand/or power relays (RY1,RY2)NOTE:Be sure to ground any static electric charge built up onyour body before handling the D.P.C.1. Replace D.P.C. board.(A) Using solder wick or a desoldering tool and 30Wsoldering iron carefully remove all solder from the terminalpins of the low voltage transformer and/or power relays.NOTE:Do not use a soldering iron or desoldering tool ofmore than 30 watts on D.P.C. contacts.(B) With all the terminal pins cleaned and separated fromD.P.C. contacts, remove the defective transformer/powerrelays, Replace components making sure all terminal pinsare inserted completely resolder all terminal contactscarefully.4.4. Fan motor1. Disconnect 2 lead wires from fan motor terminals.2. Remove 2 screws at location on oven attaching orificeassembly.3. Remove orifice assembly from oven assembly.4. Remove fan blade from the fan motor shaft by pulling itstraight out.5. Remove 2 screws holding fan motor to orifice.6. Separate the fan motor from the orifice assembly by freeing2 catch hooks on the orifice assembly.4.5. Door assembly1. Remove door C from door E by carefully pulling outward,starting from upper right hand corner using a flat bladescrewdriver.2. Separate door E from tabs on door A and remove door A.3. Open Door E at the opening angle of approximately10°(Note: The door cannot be removed if the openingangle is greater than 10°).4. Remove the door E from its hinges by pushing the door Eupward and out.5. Remove door screen B from door A.6. Remove door key and door key spring.To re-install components:1. Place the door’s lower hinge pin into the bottom hingehole.2. Use your left index finger to support the door’s lowerhinge pin while guiding the door’s upper hinge pin intothe top hinge hole.3. Lower your finger to seat the door onto the hinges.4. Replace other components.NOTE:Door alignment is crucial. If door is misaligned,apply pressure until alignment is achieved.NOTE:After replacement of the defective component partsof the door, reassemble, and perform microwaveleakage test.13NN-T695 NN-T685SF PreviousNext |
