GHD Hair Straightener Repair

GHD 4.0 Pink

This model is a MK4 pair of GHD straighteners in Pink. Temperature regulation is performed by a thermistor.

Normal operation is as follows:

If the temperature of the irons is below 5 degrees C then they will not work and the will emit a continuous beeping sound. To fix this, just bring them back up to normal temperature (gradually!) and then try again.

We stock lots of 4.0P spare parts in this section of the spares shop. This includes replacement cables (GHD 4.0P Cable) and the cable replacement method is described here.

The heater elements are 70 Ohms each. When connected to the PCB they are in parallel, so you will measure 35 Ohms (if they are both working). See the heaters page for details of the replacement heater options available.

Most common fault with this model is R8 going open circuit in the electronics causing them to be completely dead (see the R8 Failure page).

A debugging guide is available here.
