Replacing the inner frame of the door of the EMWK 1050.0
and the EMWG 1050.0
INTRODUCTION
Replacing the inner frame of the door has become one of the repairs most carried out by technicians on
the new series of compact microwave ovens (replacing hinges, handles and catches).
In order to be able to re-use individual elements without any damage we have below listed the correct
procedure for removing the door and its components. The inner frame is only pressed on without the
help of any devices such as screws or pins.
PROCEDURE
Removing the door
1. Pull the door right open.
2. Insert rivets into the holes of the hinge.
3. Pull the door upwards out of the hinges.
Removing the inner frame
1. Lift up the frame direct next to the hinges and remove it.
The frame is a little thinner at this point and can be lifted
out more easily.
2. Firstly use a screwdriver to carefully lift out the frame on
the outside between the two hinges direct next to the
glass.
3. Repeat this procedure on the left side.
4. Remove the inner clips on both sides of the frame.
5. Finally carefully remove the silicon sealing.

Re-assembling the inner frame
1. Insert the hob seal all around, without any gaps. Begin in the centre of the underside of the new
frame. The beginning and the end must meet. Make sure that the seal is not deformed.
2. Put the frame into the hinges and align it with the door.
3. Now begin pressing the frame on the underside and check
to ensure that the inner profiles on the door are properly
fitted (2 elements). Make sure that the clips are in the
proper mounting position.
4. Now press the left side and check here too to ensure that
the profiles and the clips have been properly fitted.
5. Repeat these steps on the other two sides.
6. Now press around the inner edges and make sure that the
clips are correctly positioned.
7. Check all around the outer frame. It must be fully inserted and must touch the glass surface.
Re-assembling the door and the closing device
1. Remove the rivets and suspend the hinges in the holders.
2. Close the door and check the respective positions with the control panel.
3. Align the door and the hinges again if necessary.
4. Check to ensure that the micro-switches are working properly and that the door closes smoothly.
Attention!
It is very easy to remove the door, but the inner frame may break while you are
doing so. To avoid having to replace the whole door, the frame is available under
spare-part no. 528949.
