If the power to the freeze dryer is lost for any reason during a freeze or dry cycle, the freeze dryer will go into a limp mode and turn on the refrigeration only. While in this limp mode it will not heat the shelves or turn on the vacuum pump. This protection is there to help make sure the user evaluates the situation after the power has been restored to see if the food is salvageable and or what part of the cycle the machine should go to in order to restart.
If there is a concern, update the software to the latest version. The firmware download and the instructions for how to do it can be found at the link below. There are lots of changes we make to the software to handle errors better and communicate with sensors better. Simply updating the software may resolve the issue.
