SIRIUSHAIR® Replacement Heater with Welded 229°C Thermal Fuse

Upgrade your repair with this high-performance SIRIUSHAIR® replacement heater, engineered for use across multiple GHD models with compatible control boards.

Developed and refined over several years, this heater delivers reliable thermal performance, enhanced durability, and improved safety through its integrated welded thermal fuse design.

⚠️ Important Compatibility Information

This heater is designed for use with compatible and correctly programmed control boards only.

Suitable for:

• GHD Gold (S7N261)
• GHD Max Gold (S7N421)
• GHD Platinum+ (S8T262)
• GHD Original (S4C242)

✔ Key Features

• SIRIUSHAIR® manufactured replacement heater
• Integrated 229°C thermal fuse
• Aluminium-encased fuse for accurate temperature sensing
• Welded connections (no soldering) – reduces oxidation and failure risk
• Designed to match original GHD thermal performance
• Extensively tested for reliability and consistency

⚠️ Critical Installation Information

This is a specialist component and requires appropriate knowledge and equipment.

Correct operation depends on the motherboard being programmed to accept the heater characteristics.

• GHD Original (S4C242)

If fitting to this model the silicone black fuse cover does not fit over the fuse, the silicone top can be cut off and the fuse fits, this does not affect safety or the fuse operation.

⚠️ Performance Notes

Without correct programming:

• Approx. 60% chance of reaching 180°C when replacing both heaters
• Typical output may be around 155°C

Improved results:

• Using one original GHD heater + one SIRIUSHAIR® heater increases success rate (approx. 80%)

⚠️ Critical Model-Specific Warning

For S7N261 / S7N421 models:
