Heat Press Replacement Parts | How to Guide (2024)

Replacement parts in heat presses are the components that wear out over time and are changed with new ones. Fuses, Heating elements, relays, and switches are critical parts of Heat presses for proper functioning.

Heating elements wear out at high temperatures during mug pressing. Replacing the burn-out heating elements with new ones gives a proper heating environment in mug presses. Fuses and ON/OFF switches are the other replacement parts that get damaged due to power surges and electrical issues. Prompt replacement of such parts is necessary to ensure the heat press functions safely and effectively.

Heating Element of Heat Press

The heating element in heat presses produces the desired temperature and transfers it to the object under process.

Nichrome is one of the best heating elements containing 80% Nickel and 20% Chromium wire. It is an ideal material because of its high resistance and formation chromium oxide layer when heated for the first time. Heating elements can be in straight and curved forms according to the specification of heat presses.  

Fuses in Heat Press

Fuses in heat presses are the protective components to prevent damage to the internal parts in case of power surge and excessive current.

Nearly all electrical machines have fuses in their circuit breaker boxes. Fuses are classified into 2 types;

  • AC Fuse
  • DC Fuse  

AC fuses and DC fuses are designed to protect electrical appliances from excessive power. Still, they are not interchangeable because they have different characteristics that make them suitable for different applications.

Heat press machines work with DC fuses, and Fuse 3A is their best option.

How to Change Mug Press Heating Element? (Step by Step)

Replacing the damaged heating element with a new one is tricky. With the help of proper tools and patience, it is certainly possible.  

Step -1: Disconnect the Power Source

Before starting the element replacement, switch off the mug press and remove the power lead from the socket.   

This is important for your safety, as working on a mug press is dangerous if it’s still connected to the power source.

Step – 2: Remove the Heating Element Cover Screws

After disconnecting the power source, unscrew the collar by turning it anti-clockwise and disconnect the connector.

Now, unscrew the 4 black-capped screws from the clamp using your hands. Sometimes Philips screws are used in clamping the arm, which needs a Philip screwdriver.

Be gentle in removing the cover to avoid damaging wires and other components.

Step – 3: Remove the Element from Heat Press

Now, disconnect all the wires connecting the heating element. If you are a beginner, make a drawing or take notes for proper connections in the new heating element.

Now, take the old heating element out of the mug heat press.

Step – 4: Install a new Heating Element

Carefully place the new element and align it on the position. Connect the wires with the new heating element with the help of a plier.

Place the cover over the heating element and tighten the screws properly.

Step – 5: Test the Mug Press Now!

Once the new element is in the mug press, assemble all other parts. Connect the mug press to an electrical source and ensure the new heating element works properly.

If everything is functioning properly, you can use your mug press again.

How to Change the Fuse in Heat Press?  

In most of the heat presses, a 3A fuse is used. But due to power surges, it gets damaged. By following these steps, anyone can replace it without any danger.

Step- 1: Unplug the Current Lead

Make sure you disconnect and turn off all the switches of the heat press machine. If the heat press temperature is high, wait to cool down to room temperature.

Step- 2: Open the Control Panel

A control panel is essential in each heat press setup to measure and distribute the electrical supply to auxiliary heat press parts. Unscrew it and check its fuse.

Step- 3: Replace the Fuse

After opening the control panel, remove the old fuse and replace it with a new 3A fuse. Carefully check that both sides of the fuse remain connected to the electrical supply. The heat press’s main switch is connected to the panel board. Check whether the signal is passing to the machine or not.  

Step- 4: Close the Panel Box 

After checking that signal is passing correctly, you can close the panel box. Turn ON the main switch and check the results.

Pro Tip: use a circuit breaker in the panel box to cut the supply in case of a power surge. Otherwise, a fuse can’t bear a high electrical load and cause damage to the fuse and heating element.


Heat presses are essential for custom apparel and fabrics. If a heat press is malfunctioning or experiencing a heating issue, it is essential to check the heating element and fuse.

Replacing a heating element in a heat press will resolve the heating issue and enhance the lifespan and performance of the heat press.

Replacing a fuse will help supply regular electrical power to the heat press. A high quality and reliable fuses and heating elements will deliver the best results in the long run.
