How to Change the Thermal Fuse of a Steamer and Iron

The thermal fuse (or thermal fuse) of the steam generator is a safety component for the device.

  • The thermal fuse protects the device in the event of thermal overheating or abnormal regulation from the boiler.
  • For example, when the boiler exceeds the programmed temperature limit, it cuts off the power to the steam generator and breaks.
  • In case of breakage, it must therefore be replaced, because it cannot be reset. This prevents the steam generator from being seriously damaged following a new thermal anomaly.

The thermal fuse of the steam generator is located inside the casing of the steam generator, it is fixed on the boiler.

Steamers and irons are everyday appliances that use heat and steam to press clothes. One critical component of these appliances is the thermal fuse, a safety device that prevents overheating by cutting off the power when the temperature reaches a certain threshold. Over time, the thermal fuse may blow and need replacement. This article will guide you through the process of changing the thermal fuse of a steamer and iron.

Signs of a Blown Thermal Fuse

Before proceeding with the replacement, it’s crucial to identify the signs that indicate a blown thermal fuse:

  1. Iron or Steamer Won’t Heat: If your appliance doesn’t heat at all when plugged in and switched on, the thermal fuse might have blown.
  2. Intermittent Power Loss: If the power to your steamer or iron cuts off during use and then comes back on, the thermal fuse could be the issue.

How to Change the Thermal Fuse

Step 1: Safety Precautions

Ensure the steamer or iron is unplugged and has sufficiently cooled before starting any repairs. Safety should always be your primary concern when working with electrical appliances.

Step 2: Purchase a Replacement Fuse

You’ll need a new thermal fuse compatible with your specific appliance. Check the old fuse or the appliance’s manual for the required fuse rating.

Step 3: Disassemble the Appliance

Using a screwdriver, open the appliance’s casing by unscrewing any fasteners. Keep all parts and screws in a safe place for reassembly later.

Step 4: Locate and Remove the Old Fuse

The thermal fuse is typically a small cylindrical component found near the heating element. Once located, remove the old fuse by disconnecting it from the wires. This can typically be done by unsoldering or cutting the wires. Make sure to note where each wire connects to replace the new fuse correctly.

Step 5: Install the New Fuse

Attach the wires to the new thermal fuse in the same configuration as the old one. This is where you may need to solder the wires to the new fuse. Make sure the connections are secure and insulated to prevent any short-circuits.

Step 6: Reassemble the Appliance

Once the new fuse is installed, reassemble the appliance, ensuring everything is correctly aligned and securely fastened.

Step 7: Test the Appliance

With the new fuse installed, it’s time to test the appliance. Plug it in and switch it on to check if it’s heating properly.


Being able to change the thermal fuse of a steamer or iron can extend the appliance’s life and ensure its safety. Always prioritize safety when dealing with electrical appliances, and don’t hesitate to consult a professional if you’re unsure about any step. Regular maintenance checks, including checking the thermal fuse, can help prevent costly repairs and ensure your appliance continues to operate efficiently.
