Many home master, thinking that they are already quite experienced, overestimated their strength and at the slightest faults begin to look for the problem in depth, while she lies on the surface. The result of such repairs can become a full-out microwave oven failure. After this no one person does not take up its recovery.

Sometimes there is no need to repair even open the device - the solution may lie on the surface

About repairing the microwave with your hands in detail on the example of the oven "Samsung"

Let's start with the most simple faults which may occur during operation. Do not immediately run to the store for a new device or service - to take the device for repair. Most problems can be solved independently.

Microwave minor faults and their solutions

Quite often fail out of the door locks. This can be avoided if you do not slam it, and not to open the sharp jerk. Often the occurrence of faults - fault of the user. For repairs need to purchase a locking mechanism and replace it yourself.

In no case can not include a microwave oven with the door unlocked. Modern models from this protected automation, but the older ones may be included, if the hand to press the door, however, is strictly prohibited. At any slightest fault of this unit, immediately disconnect it from the network and do the repair or to seek help from professionals.

The door should open and close gently, without unnecessary jerks, claps

If microwave "Samsung" is not included, the reason for "failure" may be a voltage drop in the main power supply. Conveniently, if the hand is the meter - it is possible in real time to measure the voltage. If such a device is not present, you can roughly determine the network parameters using the wire holder and the bulb - on heating spirals clearly shows the voltage drop. However, be prepared for the fact that in a strong excess of the norm lamp burns out or even burst.

Rectify this situation, if it frequently occurs, it is possible by setting a stabilizer for entry to the apartment, or separately at an outlet of the microwave oven.

That's what may be a power in the socket - what wonder that the microwave oven does not work?

Microwave oven can not be turned empty. If no microwaves begin heating the object reflected from the walls of the device. Sooner or later they will bring down the magnetron. Fix it quite difficult, it is easier to buy a new one. This is what happens if you include microwave empty.

Repairing a microwave oven with his own hands when a serious malfunction

The reasons why the microwave is no longer warm, maybe a few. Most often, they are the problem:

  • the control unit (violation timer);
  • power line;
  • Fuse (sharp voltage drop may disable it);
  • condenser;
  • high-voltage diode;
  • magnetron (the most expensive parts of the microwave oven).

Now we try to understand in detail how it is possible to eliminate such failure - how to repair a microwave oven with his own hands.

Repair of microwave ovens with their own hands is possible, but requires care and accuracy

Repair of microwave ovens with their hands in case of failure of management and violation of the timer unit

The first step is to turn off the oven from the mains, remove the screws behind, remove the protective cover. Next, carefully inspect the management fee for burning-off the conductive paths, swelling, burning elements. It happens that the microwave begins to live his life - may turn on, off, refuse to work. There may be a problem in the touch panel to malfunction. In any case, although such details, and can be restored, but how long they have worked for. Much more profitable to buy a new unit, a keyboard, setting them in place of the old.

By purchasing parts to replace, select marked the same label that stood earlier. So you will save yourself from unnecessary expenses. By the way, these purchases can not be returned or exchanged.

Repair control unit - soldering jumper instead of burned tracks

Microwave oven operates, but stopped warming due to problems in the power circuit

This happens quite often. The first thing is to check the fuse of the magnetron circuit (high voltage). When it is blown lights microwave oven and rotating platform are in working condition, and a magnetron (microwave gun) is not receiving power. It is treated by replacing the high-voltage fuse.

It looks like a high-voltage fuse in a protective casing

Why microwave oven operates, but does not heat food: check the capacitors

Scheme microwave multiplier comprises a capacitor, and communicating capacitors. All of them should be checked with an ohmmeter (multimeter also has this feature). They can become the reason that turns the microwave, but not warm. If found defective, they should be replaced.

It makes sense to check the high-voltage diode. If it is not "ringing" in any of the parties, it is necessary to replace it.

The high-voltage diode - if he does not prozvanivatsya, it should be changed

Microwave works but does not heat: looking for the cause in the magnetron

The main and most expensive part of the microwave oven - magnetron. If all of the above problems have not been confirmed, the problem is more serious than originally thought. Most often, the filament burns out, you can check that by measuring the resistance. If there is no resistance, then confirmed concerns about the extra costs. This is the reason that the microwave works, but not warm. Repair the magnetron does not make sense - the work is labor intensive. Simply buy a new one.

Before purchasing overwrite old data magnetron, its marking. Burnt piece is better to take with them along with the rewritten markings for comparison.

Why microwave sparks when working: Causes, Remedies

The most common cause of such malfunction becomes user carelessness. Turning apparatus with an empty platform metallic objects in the operating device, drops of dried fat mica plate - here because that similar trouble may occur. Even dishes with gold or silver trim It can not be used to heat up with microwaves, not to mention a stainless steel or enameled steel container. Consider the causes of sparks and troubleshooting.

Faults microwave, causing crack and occurrence of sparks

Mica plate, if not in time clean from her has got fatEventually begins to break down. This occurs due to the heating of food debris that had accumulated on it. As a result, the mica plate (diffuser microwaves) appears small black spot, which quickly expands during operation of the microwave oven. The process is accompanied by smoke, sparks, bang.

The consequences of burning mica plate (diffuser microwaves)

Crackling and sparks inside a microwave oven: what to do, how to troubleshoot

The first thing you need to thoroughly wash the inside of the microwave oven. To replace the better to buy a larger plate. Annexing the old, cut out the desired shape with scissors, process the edges with sandpaper. Further note and drilled holes for fastening screws, after which it remains only to fix the cut plate screws.

We note the pencil outline of the old plate and cut a new

Important information!

Removing mica plate, look at the state of the cap of the magnetron. If necessary, it should be replaced, too.

Another reason for cod and sparks may become enamel peeling chamber. This happens when the stove to warm up putting too much crockery. It rubs against the wall, leaving scratches which give rise to sparks, and can easily damage the magnetron. When the scratches make these steps.

  1. Thoroughly washes away the camera from the stubborn fat.
  2. We clean the scratch with sandpaper, degreasers.
  3. Apply the primer, and after 2-3 enamel layer (food, refractory or conductive).
  4. We are waiting for the complete drying, after which the device can be used.

This microwave oven can not be used - need restoration and replacement are already beginning to burn through the mica plate

Other possible failure: Causes, Remedies

Often that heating is performed, the light within the chamber is ignited, and the platform is not rotating. The reasons for this may be:

  • improper installation of the plates;
  • plucked drive gear;
  • failure of the engine;
  • bad contacts.

With a plate of the problem is easily solved - it is only necessary to correct. If the reason is not in it, it is necessary to disassemble the device. Failure of gear reducer - it is a problem that occurs more frequently in new models of microwave ovens. In pursuit of cheaper products steel producers to establish the short-lived plastic gears (metal stood on older models). If this is the case, then treated with a sore replacement gear - to restore the teeth of gears unrealistic.

Plate should clearly fall into the grooves

geared motor, rotating pan can get damaged by power surges. In this case, they will burn out one of the stator windings. The result is a motor of the refusal. Previously, the engines could be given for repairs. Their rewinding, and they can function again. Today, these workshops have not: in the case of such a failure would have to buy and install a new one. The main thing - to rewrite marked clearly and correctly. Otherwise, the engine just does not fit your model.

Solving the problem of poor connections is quite simple. All connections have to be cleaned from the oxide, if necessary, and redirect to tuck in the reverse order.

What if the microwave oven is not switched on

If the microwave does not turn, the causes should be sought in the sockets, plugs, wires or opening the fuse 220 V. Outlet check prozvanivat wire and fuse with a multimeter. Defective parts replaced by a new one. If you think about it, then this is a simple problem that can happen with your microwave oven.

Introduction of burnt fuse microwave oven requires replacement

To summarize

Microwave - required for any home appliance. But for it to work smoothly, and your food will not stay cold for him to follow. Fat droplets that fall on the chamber walls, it is better to wipe at once, and make a complete cleaning at least once a week. This eliminates the burning mica plate, as well as failure of the magnetron. Plates with a silver or gold pattern - a direct damage to the equipment, it is also to be remembered. Utensils should fit the size of the rotary tray or slightly less - this will protect against scratches on the chamber walls. By following these simple rules, you will extend the life of your microwave oven for years to come.

Take care of the technique - it will prolong its life for years to come
