1. Preparation

Step 1: Confirm the heating element type

First, you need to confirm the type of heating element your equipment is using. If you are unsure of the heating element model, you can refer to your equipment’s manual or ask the manufacturer.

Step 2, turn off the power of the equipment

Before replacing the heating element, be sure to turn off the power to the equipment to ensure safety.

Step 3, prepare the necessary tools and materials

You need some basic tools and materials to replace the heating element, including wrench, broom, vacuum cleaner, cleaning cloth, insulating tape, insulating porcelain tube, high temperature resistant wire, etc.

Step 4, Remove the old heating element

The heating element is typically secured to the furnace or heating system with screws, brackets, or clamps. Remove these fasteners to free the old heating element from its mounting location.

Step 5, Measure the dimensions

Measure the dimensions of the old heating element to ensure that the replacement element is the correct size and shape. This will ensure that the new heating element fits correctly into the mounting location.

Step 6, Clean the area

Remove any debris or residue left behind by the old heating element. This will ensure that the new heating element is properly secured and free from any obstructions.

2. Replace the heating element

The first step, disassemble the old heating element

First, disassemble the old heating element. For Silicon Carbide Heating Elements and MoSi2 Heating Elements, it is usually necessary to remove the ceramic tube covering the heating element and then use a wrench to remove the screws holding the heating element in place. Once disassembly is complete, remove dust and residue with a broom and vacuum cleaner.

Step 2: Install the new heating element

Fix the new heating element in place, taking care not to damage the ceramic tube, and secure the new heating element with screws. When connecting the wires of the new heating element, make sure that they are firmly and correctly connected. Use insulating tape and insulating porcelain tubes to protect the wires and the heating element.

Step 3: Test the new heating element

After the replacement is complete, you need to test the new heating element for proper operation. Turn on the power and observe whether the heating temperature is normal. You can also use a multimeter or a thermal imaging camera and other tools to test the current, resistance and heat output of the new heating element and other parameters.

3. Precautions

When replacing the heating element, be sure to pay attention to safety. Make sure the power to the equipment is turned off and use insulated tools and materials to do the job.

Replacing heating elements requires attention to detail. When removing and installing heating elements, be careful not to damage other equipment components and heating elements.
