My machine is not heating

On first use, the heater will default to a temperature 1°F higher than the current room temperature. Thereafter, the heater will remember the last target temperature set.

The heater will not operate unless the target temperature is above the room temperature.

  • Switch the machine on.
  • Increase the target temperature above the temperature of the room.
