GHD Air Hairdryer
The repair service for the GHD Air model is HERE
The Air hairdryer can be taken apart by removing the plugs above and below the speed/heat switches which gives access to two screws. Once these screws are removed the back half of the case hinges upwards and the two halves come apart.
The screws are security types and require a special bit to undo them. A flt bladed screwdriver of just the right size can be forced into the screw head and they can be removed carefully. However if you break the screw head you will not get these apart!
Inside there are a few basic components:
- A small PCB which has the fan speed and heater switches on it
- A motor with a radial fan blade
- A heater element with built in 184 degC thermal fuse
The PCB controls the power to the motor and the heater. The fan sucks air in the back of the hair dryer and blows it through the case and over the heater element.
There is a push button mounted in the case plastics which disconnects the heater to enable easy switching from hot to cold air.
Not much to it really!
Here are some photos of the components:
The switch PCB
The Motor
Common issues are worn out bearings. The motor will be noisy. You can see the wear if you try to wiggle the motors shaft from side to side.
The bearings can not be replaced.
The heater assembly
With heat resistant cover to stop the plastic case getting hot / melt.
You can see the "cold" button inline with the wiring.
The Heater
Radial fan
This sucks air in the back and flings it sideways which then gets funneled down the hair dryer
This is a broken example where some of the blades have come off.
Thermal fuse inside the heater
The heater element coil has been moved to the side so you can see the thermal fuse
Cable
The cable has a custom moulding on the end which acts as a strain relief with hanging loop.
(this is a broken one that has been cut up!)
A faulty cable can be replaced if the strain relief has not been bonded to the cable.
