OUTER CASE REMOVAL

To remove the components, procedure as follows.

1.Disconnect oven from power supply.

2.Remove screws from rear and along the side edge of case.

3.Slide the entire case back out about 1 inch (3 cm) to free

it from retaining clips on the cavity face plate.

4. Lift entire case from the unit.

CAUTION: DISCONNECT OVEN FROM POWER SUPPLY BEFORE REMOVING OUTER CASE.

POWER TRANSFORMER REMOVAL

1.Disconnect oven from power supply and remove outer case.

2.Discharge high voltage capacitor.

3.Disconnect filament leads of transformer from the magnetron and capacitor.

4.Disconnect high voltage lead of capacitor from the transformer.

5.Disconnect wire leads from the transformer.

6.Remove two (2) screws holding the transformer to the base cabinet.

Re-install

1.Rest the transformer on the base cabinet with its primary terminals toward rear cabinet.

2.Insert the two edges of the transformer into two metal tabs of the base cabinet.

3.Make sure the transformer is mounted correctly to the corners underneath those tabs.

4.After re-installing the transformer, secure the transformer with two screws to the base cabinet, one is with outer tooth washer and the other is without outer-tooth washer.

5.Re-connect the wire leads (primary and high voltage) and high voltage lead to the transformer and filament leads of transformer to the magnetron and capacitor, referring to the “Pictorial Diagram”.

6.Re-install the outer case and check that the oven is operating properly.

NOTE HOT (ORANGE) WIRE MUST BE CONNECTED TO THE POWER TRANSFORMER TERMINAL NEAREST TO THE TRANSFORMER MOUNTING SCREW.

MAGNETRON REMOVAL

1.Disconnect oven from power supply and remove outer case.

2.Discharge the high voltage capacitor. Disconnect filament lead of transformer from magnetron. Disconnect high voltage wire lead from magnetron.

3.Carefully remove four (4) mounting screws hold the magnetron to waveguide, when removing the screws holding the magnetron to prevent it from falling.

4.Remove the magnetron from the unit with care so the magnetron tube should not hit by any metal object around the tube.

CAUTION: WHEN REPLACING THE MAGNETRON, BE SURE THE R.F. GASKET IS IN PLACE AND THE MAGNETRON MOUNTING SCREWS ARE TIGHTENED SECURELY.
