GHD 4.1B

This model is a MK4 pair of GHD straightener in Black.

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.

I've heard reports that some versions suffer from the R8 failure which makes them appear completely dead. See this page about the R8 failure.

The heaters have a resistance of 70 Ohms each (nominal). When connected to the PCB, they are in parallel, so you'll measure a resistance of about 35 Ohms. I've had a few pairs where a heater element has broken. This sometimes result in the thermal fuse tripping and them being completely dead. See the Heaters page for more details.

Replacement cables are available in the spares shop and the replacement method is described here

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

A debugging guide is available here.
