If touching the surface of the stove is accompanied by a slight electric shock, you should immediately call a master. It is very undesirable to look for and eliminate the causes of problems yourself. Mistakes in the work with electrical appliances usually end badly, and achieving the result without the use of a special tool will be extremely problematic.
Causes of current leakage
The mentioned malfunction occurs under various circumstances. Among the most common options is the lack of external grounding and poor state of contact. Perhaps a violation of the insulation of wires leads to their direct contact with the body of the electric stove and the subsequent current leakage on its surface.
Also, the reasons can be the formation of a layer of dirt, water ingress into the structure, damage to electrical wiring, or malfunction of the heating element. Sometimes the problems are explained by the bad condition of the socket and errors in the connection of phases. Before you start repairing electric stoves, you need to assess the likelihood of exposure to each of the above factors, make a diagnosis and only then proceed to troubleshoot.
How do determine the cause of malfunction?
To begin with, it is necessary to study in detail the design of the device and the principles of its operation. Then you will need to prepare a tool, disconnect the stove from the power grid, and proceed to a step-by-step diagnosis.
The first step will be a visual inspection for visible damage, oxidation, and adhered dirt. The second step is to disconnect the nodes one by one in order to measure the resistance. It is advisable to use a multimeter to obtain readings. Measurements are made by gradually excluding nodes for the sake of identifying the leakage.
But to completely fix the problem on their own still can not.
