How to disassemble a microwave

At first glance, it may seem that a microwave oven is a complex device, in fact, it has a simple design. It includes the following main elements:

• magnetron;
• heating chambers;
• windings;
• waveguide.

The latter is needed to connect the magnetron to the camera.

Is it possible to disassemble the microwave yourself

Undoubtedly, it is possible if you observe basic safety rules. First: before disassembling the furnace, it is disconnected from the supply network and the voltage is removed from the high-voltage modules.

Important!When the device is turned on, it is forbidden to disassemble it.

How to disassemble a microwave: step by step instructions

Like any technical device, it is disassembled in a certain sequence.

1. Cover removal

At the first stage, remove the casing, To do this, disconnect the cord from the power socket, unscrew the fasteners from the back and side surfaces of the stove. When the cover is released, it must be moved back and raised up.

2. Disconnecting the power cable

After the cover is removed, you can begin to remove the power cord. Disconnect the leads from the filter and disconnect the middle cable of the power cord.

ATTENTION! Do not forget that an electric protective tool is used to discharge the high-voltage capacitor.

3. Dismantling the front panel and control unit

To dismantle the panel and control module, it is necessary to carry out the following manipulations - disconnect the cable from the control module. Remove the grounding hardware and hardware that secures the module. After the plastic fasteners are clicked off, pull out the control panel. The unit is mounted using three screws, which must be removed to remove. The last step is to remove the display panel.

Important! Disassembly is carried out carefully; when disconnecting the cables, pulling them is not recommended.

4. Dismantling the door

After the control unit is removed, it is permissible to proceed with the removal of the door. It is opened and the restriction plate is removed using a flat-head screwdriver. Care must be taken when working. One careless movement - and the rubber seal can be damaged. Then they lift and remove the door.

Important! After reinstalling the door, check that the circuit breakers are working.

Dismantling may affect microwave radiation level. The limit level should not be more than 4 mW / cm2.

After reassembling, make sure that the door and frame are parallel. Adjust as necessary. The door must be installed so that there is no gap between it and the chassis.

5. Extraction of a magnetron

When removing the magnetron, disconnect the cables from the capacitor and transformer. Remove the fasteners that hold them to the frame. The assembly is disconnected until the tip comes out completely from the waveguide.

When removing it must not be allowed to collide with the parts installed side by side. This may cause damage. After the magnetron returns to its place, it will be necessary to check the radiation level. It should not exceed 5 mW / cm2.

6. Removing the noise filter, diodes and other components.

To do this, perform the following manipulations:

• Disconnect the power harnesses from the filter and remove the fasteners that fix the filter grounding wire to the rear wall.
• After that, remove the filter. To do this, press the two plastic latches.
• After the power harnesses are disconnected from the tank, and the screw is unscrewed, the ground wire of the high-voltage diode is fixed.
• At the next stage, the harnesses are disconnected from the current relay and fan. Then remove the fan mount and remove.

Filter extraction should be carried out with caution, because it may contain various pathogens.

7. Removing the backlight

In order to remove the backlight, disconnect the wires from the llama and remove the fasteners that attach the duct to the magnetron. After pressing the latches of the duct, the display panel is removed.

In general, the extraction of the components of the microwave oven is carried out according to one scheme:

1. Disconnect wires.
2. Removing fasteners.
3. Removing a component.

How to disassemble the microwave door

Regardless of the manufacturer, the doors have many common design features. In particular, any door consists of several layers - a carrier (it is made of metal), protective and external, for the manufacture of which plastic is used.

To disassemble the door, you will need a knife and two slotted screwdrivers. The first thing is to separate the seal frame, in the next step, remove the outer part, it can be fixed using traditional fasteners or using plastic clips. And immediately they pull out the glass. The analysis is over.

Important tips for better disassembling the microwave

When starting disassembling, you need to remember that there are many models of these household appliances on the market from different manufacturers, and each model may have separate subtleties in disassembly. For example, for disassembling some models, an ordinary screwdriver with a cross-shaped slot may not be suitable; they use fasteners with a different shape of the slots.

For those who perform this operation for the first time, it makes sense to accompany the disassembly process by photographing each stage, it can help with reassembly.
