What is heating element?

A heating element is an important part of many industrial and household appliances and is the central component that provides the source of heat in a heating application.

It can be made of different materials, including silicon carbide and MoSi2, and also comes in different shapes and sizes, depending on the shape and specifications of the heater body.

Why heating elements break down?

However, over time, as the heating function is used continuously, the heating element may begin to deteriorate and its performance may gradually decline or even become useless.

In this article, we will discuss what a bad heating element looks like, with a particular focus on silicon carbide and MoSi2 heating elements.

Silicon Carbide Heating Elements

Characteristics of Aging

One of the most common phenomena of a bad silicon carbide heating element is a significant decrease in heating capacity. If the heating element is not able to provide the same amount of heat as when it was first installed, then it has gone bad and has probably reached its expected lifespan.

In addition, A heating element that emits strange odors or smoke may be a sign that the heating element has been damaged internally or is experiencing electrical problems.

Visualize. If you can see the heating element, you may notice some signs of damage, such as cracks, chips or discoloration of the surface.

This can be caused by prolonged exposure to high temperatures, as well as physical stress. If you observe these phenomena, replace the heating element as soon as possible to prevent further damage to the furnace or safety problems.


MoSi2 heating element

Characteristics of Aging

Like silicon carbide heating elements, MoSi2 heating elements can deteriorate and become damaged. One of the most common occurrences of a bad MoSi2 heating element is a decrease in heating capacity, which can lead to reduced efficiency.

In addition,MoSi2 elements may begin to emit strange odors or smoke, indicating internal damage or possible electrical problems.

Visualization. Damage to MoSi2 elements can also occur due to prolonged exposure to high temperatures or compression by external forces, which can result in cracks, chips or surface discoloration.

Such problems should also be replaced as soon as possible to prevent safety problems from occurring.

In summary, regularly checking your heating elements for deterioration and damage and replacing them when necessary is an important part of the job. This helps the appliance or heating equipment to continue to operate safely and efficiently.

With the above methods, it should be easy to tell if the heating elements have been damaged, and if they have been damaged or are not heating as efficiently as expected, replace them with new ones as soon as possible to keep the equipment running properly and avoid potential safety hazards.
