Frequent malfunctions of electric ovens Sol
Breakdown of the oven, like any other household appliances, always happens at the most inopportune moment. The device stops turning on at all or error codes appear on its control panel. You can understand the reasons for such an unpleasant situation by performing oven diagnostics.
Sol electric ovens
Modern ovens are available in two versions – independent and dependent. The former are equipped with a separate control system that is not connected to other household appliances. Dependent ovens are made together with the hob and are equipped with a common control. In electric ovens, heat is generated using heating elements.
As a rule, this is the top, bottom heating or combined mode. The presence of the grill function greatly expands the possibilities for cooking. Equipped with a convection mode ensures uniform heating of products. The heating temperature of the working chamber of electric ovens is adjusted on the control panel. At the same time, the setting of the temperature and cooking time is carried out by electronic or electromechanical control. Modern models are equipped with additional functions of microwave, steam cooking.
What can go wrong in the Sol oven
If the oven does not turn on, first of all it is necessary to exclude external causes – check the presence and magnitude of voltage in the outlet. If this is not the reason, then you need to deal with the device itself – there may be several reasons for breakdowns. Moreover, most of them are usually caused by errors in the operation of the oven.
The heating element – TEN – is a metal tube with a wire passing inside. The metal of the wire has a high resistivity, so when current passes through, the wire heats up. In addition to the wire, there is a special insulating substance inside the tube – magnesia, which prevents contact between the wire and the sheath. Electric ovens use several types of heating elements:
spiral – has a single or double spiral, the degree of heating smoothly changes with a rotary knob;
solid – installed under a metal plate, has several stages of heating;
halogen – made of durable refractory glass; the main element is a lamp with a reflector; in household appliances, such a heater is rarely installed.
The reason for the failure of the heating element may be its physical wear. Intensive operation in the heating-cooling mode causes the loss of the properties of the heater shell. One of the most common causes of a non-working oven is a burned-out heater. Visually, this can be seen if dark spots, swellings, cracks and other mechanical damage appear on the heating element. A damaged heating element after turning on the oven is red-hot. A factory defect in the heating element can also cause it to break, but this situation is extremely rare. Manufacturers pay great attention to quality control of this part. A damaged or burnt heater must be replaced.
The thermostat controls the temperature inside the oven. When the temperature reaches the set value, the thermostat closes or opens the electrical network that feeds the heating element. Switching off and on occurs due to compression or expansion of the gas inside the thermostat or due to expansion or contraction of the bimetallic plate under the influence of temperature. If the thermostat fails, the oven may not turn on at all or work without controlling the heating of the chamber. In this case, an uncontrolled increase in temperature is possible, which is very dangerous. You can check if the thermostat is working with an oven thermometer. It must be placed inside, set the temperature controller to the minimum heating. A good thermostat should turn off the heaters after about 10 minutes. Then you need to compare the temperature on the thermometer with the one set by the regulator.
An electronic module, consisting of a motherboard, a processor and a memory board, is responsible for the execution of installed programs. Electronics can fail during a power surge. Also, the program may crash due to incorrect actions of the user himself. For example, when introducing a new command without canceling the previous one. To fix the problem, you can try to reboot the module. If this does not help, it needs a flashing.
The oven may not switch modes or not turn on at all due to a faulty touch screen display. It will not work to repair the touch panel on your own – for this you need to have special diagnostic equipment and experience. It is better to entrust the repair of this equipment to specialists.
In ovens equipped with a grill function, the spit is driven by a separate electric motor. If it breaks, the rotation function does not work. In many ovens, the rotation of the spit is carried out through a belt drive. This design is due to the limited width of the oven and the ability to simplify the design. The belt transmits torque from the engine to the spit. If the belt breaks, the engine will continue to run, but the spit will not rotate. Replacing the belt requires quite complex work, it is not advisable to do it yourself. Also, the rotation of the spit will be disturbed when it disengages from the drive clutch. In this case, you can try to install it yourself in place or slightly tighten the hook.
Uniform distribution of heat in the working chamber is ensured by installing a special fan. When it fails, the correct air circulation is disturbed, which causes uneven heating and baking of the dishes being cooked. Most often, a fan failure occurs due to a break or short circuit in the windings of its electric motor. There can be only one solution to the problem in this situation – the replacement of faulty elements.
Convector heating element
An additional heating element installed in many models of ovens with convection mode provides more uniform heating of the working chamber. The heating element may burn out due to voltage fluctuations in the network, violation of operating conditions. A failed heating element must be replaced, it cannot be repaired.
The temperature probe allows you to more accurately control the temperature during the preparation of various dishes, since it measures it directly inside the product. There are two types of thermal probes – wired and wireless. The first has the shape of a needle, is stored separately from the oven and is connected to a special channel in it. The second is stored in the oven door and does not require connection to a special channel. The temperature probe can completely fail or give false information. The reason may be a malfunction of its sensitive elements. As a result of violation of the rules of operation, they can melt, close. Also, false information can be transmitted if the control unit malfunctions or the cable of the wired temperature probe is damaged. In this case, it is necessary to replace the elements.
Many modern ovens are equipped with a steam generator. This option significantly expands the capabilities of the appliance, allowing you to steam, bake, stew vegetables and meat. At the same time, dishes are obtained almost dietary, retain their beneficial properties. The water poured into a special container flows down the tube into the steam generator bowl located in the working chamber of the oven. There it heats up and turns into steam. If the water runs out during cooking, a corresponding message appears on the display and an audible signal sounds. The reason for the breakdown of the steam generator may be a malfunction of the heater, other structural elements.
One of the malfunctions in combined ovens is the breakdown of the microwave module. In this case, the backlight and ventilation can work. First of all, you need to check the fuse. If everything is in order with him, then they call the magnetron power circuit tester and check the magnetron itself. But, such work should not be carried out on your own, it is better to contact specialists.
The pyrolytic cleaning system is one of the most efficient and powerful ways to clean electric ovens. The method is based on the principle of combustion – pollution of the working chamber burns out under the influence of high, up to almost 500 degrees, temperature. To remove the unpleasant odor that appears during the pyrolytic cleaning process, manufacturers install special filters. The main advantage of this type of cleaning is obtaining a high-quality result without the use of harmful chemical detergents. After completing the process, it is enough to wipe the walls of the oven with a damp sponge to remove soot. With this mode of cleaning, increased requirements are placed on the quality of the steel of the working chamber, heat-resistant enamel, thermal insulation of the body and door. If, when this mode is turned on, abnormal heating of the device occurs, the smell of burnt insulation appears, you must turn off the oven and contact the 24service center.
