Summary

Many products in this category see daily or weekly use, and faults frequently appear after a time. Many of these are simple mechanical or electrical faults which can be fixed fairly simply, provided the device can be disassembled.

Safety

As with all mains electrical devices, dangerous voltages may be exposed when opened.

Disassembly

Provided the device has accessible screws there's a good chance you can disassemble it, though you may have to examine it carefully in order to see how to release any clips, additionally holding it together.

Mains operated devices often use security screws in order to discourage disassembly by those who may not understand how to do so safely.

Often, the parts will be tightly packed in and need to be reassembled in exactly the same way otherwise it may be impossible to close the device. Pay particular attention to the routing of wires and the position and orientation of other parts. Taking photos at each stage of disassembly can avoid much frustration and wasted time.

Cleaning

Hair driers and electric trimmers and razors often get clogged with hairs. In the case of hair driers, hairs can get tangled around the fan and its spindle, causing the motor to run slowly, to labour or to stall. A burning smell may come from an overheating motor or from hairs caught on the heating element.

If the fan is not turning freely, this may cause a thermal fuse to blow or the motor to burn out. A thermal fuse can be replaced but it's likely that a burnt out motor can only be replaced if you can cannibalise one from a similar or identical device.

In the case of electric razors and trimmers, bits of hair can jam up the mechanism if the devices isn't regularly cleaned. Check the instructions (you may be able to find them online if the owner has lost them) and follow any cleaning instructions given. Otherwise, disassemble them as far as you can in order to expose the cutters and the mechanism driving them.

Electrical faults

Leads

Users of hair driers, straighteners and curlers often wind the lead around the device when they have finished using it. This is generally A Bad Idea since it commonly results in the lead getting more and more twisted until the strain causes it to fail. Some hair straighteners and curlers have the mains lead attached via a mechanism that allows the device to be twisted without twisting the lead, but this isn't always proof against an incorrigible twister of mains leads.

Wrapping the lead around the device indeed keeps it tidy when you put it away, but on the next use it's essential that you suspend the mains plug by the mains lead at sufficient height to allow it to untwist naturally. Simply pulling the lead will never untwist it and will only hasten the damage.

A damaged mains lead can usually be replaced with a similar type of cable, provided you can disassemble the device sufficiently to remake the connections within the device.

Repairing a damaged mains lead with PVC tape or Sugru may effect a temporary fix provided the copper isn't exposed, but such a repair will necessarily fail the visual inspection of a PAT test.
