The fuse in the F5 slot is also responsible for the SD control unit, but it is most likely to burn because of the heater fan. If this happened several times in a row, the engine is more likely to be curled, and the power of the current increases and the fuse is afloat. Frequently, the fuse of an additional stove resistor is not built.
If these symptoms are found on the warranty cars, "Avtova" recommended to the dealer centers to immediately change the fan of the stove assembly. Some owners recommend that you try to lubricate it, but given the complexity of the access to the engine, it is usually easier to perform a replacement.
