Diagnosis
The heat function works, but the spin mechanism isn't engaging. This is usually a user error with the clamp or a hair jam preventing the auto-start sensor from triggering.
How to Fix It
Ensure you're using the clamp correctly. The device only spins when the clamp is fully closed and locked onto a section of hair. Make sure you hear a distinct click when you close the clamp. If it's closed correctly and still no spin, unplug, remove the barrel, and check for a hair jam on the spindle as described above.
If That Didn't Work
The micro-switch inside the clamp that signals it's closed may be faulty or have hair/debris blocking it. Try cleaning around the clamp hinge with a cotton swab and isopropyl alcohol.
Heads Up
The barrel will not spin if the clamp is open or not securely latched—it's a safety feature. Don't try to bypass it.
