HairMaster: How to Replace the Heating Tube
The heating tubes in your HairMaster are the parts that wear down with use and can, of course, become worn out. Fortunately, replacement is easy. Safety first: turn off HairMaster, unplug it, and let the head cool completely. The heating tube is made of glass — handle it carefully.

What you'll need
How to do it
Check the serial number
You can find the serial number under the head of your HairMaster. The serial number must be over 3.000.000 for you to be able to replace the tube.
Preparation
- Turn off your HairMaster
- Let it cool down
Remove the grill
Push the metal grill toward the machine itself and pull/tilt it out. The grill is secured in 2 holes at the outer part of the arm of your HairMaster. Take a look before you start pushing/pulling.
Loosen the old heating tube
Press the heating tube slightly toward one end so the opposite end loosens from the socket, then gently tilt it out.
Stuck? Don’t use force. Give the tube a slight twist (turn it a little) while pressing in a bit. Once it’s loose, you can tilt it out without resistance – you’ll know, but it can be tricky on older machines.
Install the new heating tube
Do the same in reverse: Insert one end into the socket, press lightly, and tilt the other end into place. The same rule applies as before: Do not use force. Give the tube a slight twist (turn it a little) while pressing it slightly down into the socket.
Put the grill back on
Opposite of how you removed the grill, now guide it back toward the arm and press it against the machine so the grill engages into the 2 holes.
Power on and test
Connect power, turn on your HairMaster and check that the tube heats up steadily and evenly.
