Independent repair of ovens

Modern ovens break quite rarely, but problems in their work are not excluded. The difficulty is that the design and all its elements do not provide for outside intervention. Repair of ovens at home is usually done by replacing components and in most cases, it is carried out by an experienced master. However, in some cases, the damage can be fixed by yourself.

When it makes sense to interfere with the design

If you decide to try to repair the oven with your own hands, then you should know the situation when you should not do this. Definitely no need to open the case if:

• electric oven is under warranty;
• the information panel of the oven shows that the problem lies in the breakdown of a complex component;
• you know nothing about electrical engineering.

During the warranty period, all repairs are made. is free. Except for the following cases:

1. On the construction there are traces of attempts to open - worn or damaged heads of bolts, screws, removed seals.
2. Insects or rodents have penetrated into the oven, causing a short circuit or mechanical damage to the nodes and wires.
3. Connection is incorrect, without following the manufacturer’s recommendations.
4. Damage to electronic components occurred due to a change in voltage parameters, as a result of which it went beyond the critical limits indicated by the manufacturer.

In all cases when the warranty is removed, repairs will have to be paid. in full size. The same situation is observed when the warranty period expires.

Primary check

Before you grab the multimeter, wear gloves and get a set of screwdrivers, it makes sense to check the power supply in the oven. It is worth looking for answers to the following questions:

1. Is it powered?
2. Is the power cable okay?
3. Is there good contact between the socket and the plug?
4. Are there any signs of soot, flashing on the plug and socket?
5. Is the plug or oven fuse broken?
6. Is the power wire in perfect condition, are there any fractures, scuffs or flushes on it?

Check the fuse in the plug

If there are no problems described above, and the oven still does not start, you should check the appliance for standard faults.

What malfunctions most often occur

Consider the typical malfunctions, methods for their diagnosis and the necessary repair of electric ovens at home. As mentioned above, most troubleshooting is the replacement of components and parts.

Control system failure

If the electronic control unit of the oven fails, be prepared to pay a tidy sum for the repairs. In most cases, you don’t need to do anything to identify this problem. Modern oven models are equipped with self test system: the electronics will automatically signal by displaying an error code.

Repair of the control module with your own hands is possible only if you have experience and knowledge in electronic engineering.

Parts are replaceable, they can be ordered from the manufacturer's catalog. For users who prefer to get a baked chicken out of the oven, rather than electronic boards, it is best to call a qualified master.

If this is not possible or the qualification of service personnel is not credible, you can order a control unit wholly. This can be done on the official website of the manufacturer or in a specialized online store. It is usually not difficult to install the board in the place of the burned one.

Breakdown of mechanical timers, mode switches

Most modern models equipped with mechanical regulators do not provide for their disassembly and cleaning. Primary repair consists of removing contamination from the outside, removing contact leads and stripping plates on the controller or timer. If this does not help or does not help fully, the part should be replaced.

Some old models allow cleaning of mechanical regulators, after which the latter work perfectly, without complaints. It is necessary to perform maintenance using non-aggressive solvents, for example, white spirit or a weak solution of ammonia. To clean the oxides from the contact groups should be very fine sandpaper, special primers are used to eliminate traces of corrosion.

Failure of a mechanical thermostat

This is a detail that is often changed, including when repairs are made to gas ovens. Intervention in the design of the device is not provided. The item is replaced entirely.

Disabling superchargers

Fans blowing and grill over time cease to create high-quality air flow. If the engine is running, the impeller should be cleaned. It constantly accumulates dust, while on blown fans there is grease and oil.

After a certain period of operation, it is necessary to disassemble the oven and lubricate the engine, if it is provided for by its design.

In case of failure of the supercharger, rewind or other repair is simply unprofitable - the node is replaced entirely. Do the same with the grill motor. It is placed in a non-separable housing together with a gearbox.

Breakage TENA

The heating elements of the oven are constantly working in a critical mode. Determining whether TEN works is simple enough. To do this, turn on the oven to the appropriate heating mode and check the temperature by touching the hand in the kitchen mitten. The method works, but for a more accurate result is better. apply pyrometer. The device will clearly show the uniform heating on the area, will indicate the maximum temperature in a given mode. This will make it possible to diagnose a “burnt” TEN not only completely, but also partially.

Infrared pyrometer

Heaters are replaced after dismantling the case, it is easy to buy the appropriate part. Specific labeling can be found after the removal of heating elements or by reference data of your model of electric oven.

Conclusion

The last three elements that change without any doubts and hesitations are the backlight, thermal fuses and the touch film panel. All these parts are not subject to cleaning and repair.

The operation of the thermal fuse in emergency mode will be reported by the oven electronics, and problems in the operation of the film touch panel are diagnosed by a lack of response, the need to exert excessive pressure, random triggers. The backlight can be replaced on its own, but to install new fuses or a film sensor, it is better to contact the master.
