4.3. Low voltage transformer
and/or power relays (RY1,
RY2)
NOTE:
Be sure to ground any static electric charge built up on
your body before handling the D.P.C.
1. Replace D.P.C. board.
(A) Using solder wick or a desoldering tool and 30W
soldering iron carefully remove all solder from the terminal
pins of the low voltage transformer and/or power relays.
NOTE:
Do not use a soldering iron or desoldering tool of
more than 30 watts on D.P.C. contacts.
(B) With all the terminal pins cleaned and separated from
D.P.C. contacts, remove the defective transformer/power
relays, Replace components making sure all terminal pins
are inserted completely resolder all terminal contacts
carefully.
4.4. Fan motor
1. Disconnect 2 lead wires from fan motor terminals.
2. Remove 2 screws at location on oven attaching orifice
assembly.
3. Remove orifice assembly from oven assembly.
4. Remove fan blade from the fan motor shaft by pulling it
straight out.
5. Remove 2 screws holding fan motor to orifice.
6. Separate the fan motor from the orifice assembly by freeing
2 catch hooks on the orifice assembly.
4.5. Door assembly
1. Remove door C from door E by carefully pulling outward,
starting from upper right hand corner using a flat blade
screwdriver.
2. Separate door E from tabs on door A and remove door A.
3. Open Door E at the opening angle of approximately
10°(Note: The door cannot be removed if the opening
angle is greater than 10°).
4. Remove the door E from its hinges by pushing the door E
upward 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 hinge
hole.
2. Use your left index finger to support the door’s lower
hinge pin while guiding the door’s upper hinge pin into
the 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 parts
of the door, reassemble, and perform microwave
leakage test.
