GHD hair straighteners are a premium product which retail for a minimum of £100 in the UK. However, over time they suffer from common annoying faults which cause owners to condemn the set they have.
This set of straighteners presented ‘as working’ when first switched on. After warming up, hair straightening temperature was reached within the normal time. However, after 5 minutes of use, the temperature reduced and failed to re-heat in a reasonable time. Leaving the straighteners to cool completely would effectively reset the problem, only for the cycle to repeat again.
GHD faults are well documented on YouTube and the fault turned out to be a faulty thermocouple or thermofuse, which should regulate the temperature and cut power in the event of a fault. They do however wear out and this set of straighteners was no exception.
After dismantling, the thermal fuse was replaced for £2.70. The whole job took half an hour and saved the owner nearly £100 on a replacement.
