Electric Burners: Strange Sounds Explained

In summary, when electric burners are turned on, they make a sound similar to stretching, which increases and decreases in volume and frequency. This is caused by the metal parts expanding and contracting as they heat and cool. Similar sounds can be heard from a car engine, toaster, or space heater due to temperature changes.

Forgive me if this ends up not being a physics question, but I've noticed that when you turn on the burners (electric) they make a sound that almost sounds like they're stretching, but not a continuous sound, more like a series of closely spaced ticks. This sound seems to increase and decrease volume and frequency every so often. Does anyone know what I'm talking about, or what the cause of these sounds is?

It's just the metal parts expanding and contracting as they heat and cool. Your car engine makes those same sounds.

Although it's not as pronounced because of the smaller scale, you can hear the same thing from a toaster or space heater. Pretty much anything metallic that undergoes a serious temperature change, in fact.
 

Related to Electric Burners: Strange Sounds Explained

1. What causes the strange sounds coming from electric burners?

The strange sounds coming from electric burners are typically caused by a phenomenon known as thermal expansion. This occurs when the metal components of the burner, such as the heating coil, expand as they heat up, creating small cracks and pops.

2. Are these sounds dangerous?

No, these sounds are not dangerous. They are simply a natural occurrence due to the heating and cooling of metal components in the burner. However, if the sounds are accompanied by a burning smell or smoke, it is important to turn off the burner and have it inspected by a professional.

3. Can these sounds be prevented?

While the sounds themselves cannot be prevented, regular maintenance and cleaning of the electric burner can help minimize the frequency and intensity of the sounds. This includes removing any debris or residue from the burner and ensuring proper ventilation for the burner to cool down.

4. Do all electric burners make these sounds?

Yes, all electric burners are susceptible to making these sounds. However, the intensity and frequency of the sounds may differ depending on the quality and age of the burner.

5. Should I be concerned if the sounds suddenly stop?

In most cases, the sudden stop of these sounds is not a cause for concern. It could simply mean that the metal components have cooled down and are no longer expanding, or that the burner has reached its desired temperature. However, if the burner is no longer functioning properly, it is important to have it inspected by a professional.
