GHD 4.2B and 4.2P

This model is a MK4 pair of GHD straightener in various different colours.

Normal operation is as follows:

Switch on => Beep Once, LED on constantly
Reach operating temperature => Beep twice, LED flashes.

If they are like 4.0B's then 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.

This model is commonly faked - see the fake GHD page for more info.

Design Variations

It seems that GHD did a reasonably significant redesign of the straightener without changing the model number. Therefore there are a couple of different designs which all have a label stating 4.2B.

Type 1

This type of GHD 4.2B is very similar to previous models and uses the same cable connection etc:

Type 2

The differences are as follows:

Cables

Some 4.2B straighteners have a different cable connection to all previous GHD straighteners. The different style of connection looks like this:

This style of connector seems to have a problem where the contacts for the central pin get bent outwards and stop making contact with the pin. Therefore if your GHDs are dead, try gently bending those contacts back in with a small screw driver.

If you need a new cable for this style of connection, then unfortunately we cannot supply them at the moment.

Heater Plates

In all previous models of GHD the heater plate are held in by plate mounts that just clip onto the heater plate with plastic clips on the mounting part. In some 4.2B's however they use extra metal clips to hold it all together. This is a good thing as it removes the problem that previous models had with the plastic clips breaking off and the plates falling out.

The plates with metal clips look like this:

The clips can be removed with a small screw driver:

With the mounting part removed it looks like this:

The clip that holds the heater element in place is quite difficult to remove without bending it. It can be removed with a small screw driver as follows:

Hinge Spring

The hinge spring is different and uses a bent bit of flat metal, rather than the traditional spring.
