I have worn the heatable underwear for a while and now it doesn’t heat anymore. Is it broken?

Usually not! Sometimes the conductivity of the knitted fabric is affected by secretions of the skin (such as sweat). In an extreme case the resistance rises until it breaks the predefined frame so the Mini-Power-Controller activates the safety shut-down, which prevents further heating. Therefore the underwear needs to be washed each second day if worn intensively (please consider washing instructions!). The conductive fabric is thus cleaned and the full conductivity is restored.
