Power Transformer Removal
Removal
1. Disconnect the power supply cord and then remove
outer case.
2. Open the oven door and block it open.
3. Discharge high voltage capacitor.
4. Disconnect filament leads of transformer from the
magnetron and capacitor.
5. Disconnect high voltage leads of capacitor from the
transformer.
6. Remove one (1) screw holding the capacitor holder to
fan duct and remove the capacitor.
7. Disconnect wire leads from transformer.
8. Remove three (3) screws holding the deflector to the
cavity face plate and remove the deflector.
9. Remove three (3) screws holding the base cover to
the cavity face plate and one (1) screw holding the
base cover to the cavity back plate, and remove the
base cover.
10. Remove two (2) screws holding the transformer to
right base plate.
Re-install
1. Install by sliding the transformer on the right base
plate with its primary terminals toward the fan duct.
2. Secure the transformer with two (2) screws to right
base plate.
3. Re-connect wire leads (primary and high voltage) to
the transformer and filament leads of transformer to
magnetron and high voltage capacitor. Refer to
“Pictorial Diagram”.
4. Re-install the capacitor.
5. Re-install the base cover and the deflector.
6. Re-install the outer case and check that oven is
operating properly.
To discharge the high voltage capacitor, wait for 60
seconds and then short-circuit the connection of
the high-voltage capacitor (that is the connecting
lead of the high-voltage rectifier) against the
chassis with the use of an insulated screwdriver.
Positive Lock® Connector (No-Case
Type) Removal
1. Disconnect the power supply cord, and then remove
outer
case.
2. Open the door and block it open.
3. Discharge high voltage capacitor.
4. Push the lever of positive lock® connector.
5. Pull down on the positive lock® connector.
To discharge the high voltage capacitor, wait for 60
seconds and then short-circuit the connection of
the high-voltage capacitor (that is the connecting
lead of the high-voltage rectifier) against the
chassis with the use of an insulated screwdriver.
Make sure the wire leads never touch the fan blade.
