For a guide to debugging this model, have a look at our Mk3 GHD repair guide
Normal operation is as follows:
- Switch on => LED on constantly
- Reach operating temperature => LED flashes.
The mk3 models never beeped.
Normal causes of electrical failure are thermal fuses and cables (although see our debugging guide to confirm). If a ceramic plate comes loose, then you'll probably need to replace the plastic part that holds the ceramic plate in place (see the online shop).
This model uses the resistance of the heaters to control the iron temperature. As the nominal resistance of the heaters can change if a heater is replaced, the irons may need recalibrating after repair. See the VR1 page for more information.
GHD (i.e. the manufacturer) no longer repair this model. I've heard from a number of people that they have sent their GHD 3.1B's off to GHD with faulty cable like symptoms, only to be told "there is a fault with the PCB and we no longer stock spare parts for this model". To me this sounds like GHD are hoping you will then take up their offer of a new pair with a £30 discount. If you don't accept that, then they will charge you £10 to get your broken GHD back! All sounds a bit cheeky to me.... Of course all the non-official repair companies will happily repair them - see the Repair Service page.

- Instructions for replacing the cable can be found here.
- Instructions for replacing the thermal fuse can be found here. (If you need to buy a thermal fuse, then see the shop thermal fuse item)
- Instructions for replacing the heater element, heater plate or heater plate mounting part can be found here
The normal operating termperature is around 185 degC when measured using a thermocouple between the plates:
Obviously an infrared temperature measurement method may result in a slightly different measurement.
