Do you have any vacuum gauges at all to test the pump? ( Though I doubt that is the problem based upon your tests )
4) I made a plastic shield to protect the main circuit board of the FDer. it simply slides into place and protects the top and both sides of the board from condensation.
I thought an easier way to see what was happening would be to make a time lapse video of an entire freeze drying cycle. As I was about to prepare some apples for freeze drying yesterday, I thought it would be a good time to do that -- so out came the GoPro.

4 trays of corn takes only 16 hours, I would estimate that we have cut our FD times by 30% or more! Condensation has been decreased by 90% - no more dripping down the interior front panel and collecting on the aluminum base.
