GHD 4.2b hair straighteners with a new fuse.
Someone got in touch with a set of GHD 4.2B hair straighteners, which wouldn’t warm up. Not even the light would come on.
Make and model: GHD 4.2b hair straighteners
Cost of replacement: £85.00
Cost of parts: £2.89 (plus my time)
Hours spent on repair: 1 (plus testing)
Repair difficulty: 5/10
These older hair straighteners are well supported with spare parts and their design means that, with a systematic approach and basic test gear, the fault can be identified and parts replaced, fairly easily.
The thermal fuse on these straighteners can fail, even though the heating elements and associated wiring and circuitry is just fine. A combination of age and accidental rough handling can affect the life of the fuse, so it was the first thing I checked on these straighteners.
It was first time lucky in this case. The fuse tested open-circuit. To prove that the rest of the circuit was working, I made a temporary short circuit to the fuse connection and the straighteners powered up OK.
Time to order a new fuse. Using an eBay shop (SiriusHairUK), a fuse was ordered and it arrived very quickly, great service.
With the fuse re-fitted and the heating element re-installed the rest of the hair straighteners were ready for reassembly. Using basic tools, the straighteners went back together well and after final testing, they were ready for use again.

I love repairing things and hate throwing things away that can be saved. There’s far too much waste in the world. Many things that can sometimes appear unrepairable, are indeed repairable, with a little tinkering.
I want to encourage people who doubt their own ability to repair their things, to give repair a go. Afterall, if ‘that thing’ isn’t working, grab a screwdriver, take it apart and investigate. What have you got to lose?
I’ve been tinkering with bikes, cars, coffee machines, toys and vacuum cleaners and pretty much anything that can be dismantled since I could hold a screwdriver. I’ve worked for BT as a senior engineer and I’ve studied design, business and electronics.
Enjoy the repair diary of a tinkerer. I hope it gives you a nudge to repair your broken thing. If you can’t, I might be able to help.
