Why does my BioCharger have a 5 minute cool down period?
Your BioCharger generates internal heat and needs time to cool its internal components after a recipe has completed. The Cool Down period down allows those internal components enough time to reach ambient temperature before the next recipe runs.
Some recipes will continue to have the fan run after cool down is complete. Typically these are longer recipes. Room temperature will also affect cool down time. You may start another recipe as long as cool down period on the screen is no longer there and the regular screen is back up to allow you to start a recipe.
