It may happen that some time after the electric stove is installed, it starts to give you an electric shock. It can be quite a minor electric shock, but certainly unpleasant, especially if you have touched the stove with wet hands.
This problem should be corrected as soon as the first symptoms appear, otherwise it can lead to serious and life-threatening injuries. There is no single cause, so you need to diagnose and properly identify the root of the problem.
If you are more or less familiar with your electric stove and have basic skills with a multimeter and screwdriver, then in general you will be able to do a simple diagnosis. However, it is important to remember that any repair work on electrical appliances is dangerous if the person is not experienced and qualified.
We recommend to contact a San Diego Appliance Repair, the best appliance repair service provider all over San Diego County, guarantees that our technicians are expertly trained to repair gas and electric stoves. We will examine the systems that keep your stove working including safety fuses, sensors, control panels and coils using the latest technology, analysis and tools needed.
If you decide to inspect your electric stove yourself, remember that maximum precautions must be observed, internal inspection of the stove is only to be carried out when it is switched off. If the stove will be on, you should not touch it with wet hands, barefoot or in wet clothes.
Therefore, first unplug the stove and inspect the insulation of those wires that are in plain sight, perhaps everything will immediately become clear and you will not have to disassemble the stove. If an external inspection does not reveal anything unusual, you will have to disassemble the stove and consistently disconnect its components, ring the resistance between the electrodes of the plug with a multimeter in ohmmeter mode, so that there were no closed circuits.
- Checking the grounding
Even at the design stage of the electric stove everything is done to prevent possible current leakage from its components to the case. Grounding is used for this purpose. However, a disturbance can still occur because, although everything inside the stove is working properly, the grounding on the outside may not be present at all.
Grounding may have lost its function for various reasons: oxidation of the ground wire terminals, overheating factor, excessive exposure to UV light, destructive influence of moisture, etc. In any case, it is necessary to check the integrity of the ground loop and find out if the power supply is grounded.
First, use a multimeter in voltmeter mode or an indicator screwdriver to find the phase and zero terminals of the outlet. Then measure the resistance between the neutral terminal of the outlet and the ground terminal. The resistance should not be significant. Also, a phase may appear on the cooktop even if the outlet ground is good, but the plug terminal does not make contact with the outlet ground terminal. Check this out. Finally, you should check the cooktop chassis and the grounding terminal on the plug – the resistance should be near zero. If the problem is detected at this point, an electrician will be able to fix it.
- Checking insulation integrity
Faulty insulation can also cause a phase in the body of the stove. Insulation can be compromised at the contact points as well as on the connecting wires. Check contact continuity with a multimeter while the stove is off, and a screwdriver indicator will work to detect phase leakage on the body and components of the stove. Remember, the indicator screwdriver should not be touched with your hands when the stove is on!
Once a phase leak is detected, it will be easy to find the part of the stove that has a phase leak, which means that part needs to be repaired or replaced.
- Are the heating elements undamaged?
Faulty (punctured) heating elements can also be the cause of voltage on the stove. More often than not, the problem is in the oven. The heating element may heat up and work almost normally, but a breakdown will occur, causing current to flow through the vulnerable area. In this case, it is necessary to completely replace the punctured heating element. The heating element can be replaced by an electric stove repairman.
- Is the filter broken?
An infrequent but recurring cause of alternating voltage on the case of an electric stove is the breakdown of a capacitor designed to smooth out impulse noise. This capacitor is installed near the switching power supply, if there is one in the stove. The current pierces through the body of the faulty capacitor to the body of the stove and causes, although not very large, but perceptible and unpleasant to the touch, alternating voltages. The breakdown capacitor should be replaced.
