1. Are you using this unit a lot [well, not right now, of course. ]?
2. I saw a suggestion about using it in a basement or other cool area [a lower temperature to help the unit in its job]. Are you doing this?
Typically, one of the best places to start when you want to repair something, and you are not completely sure how to do it... is YouTube. Others have faced similar issues with their Harvest Right freeze dryers and have shared how they overcame them.

Are you still in NH?
Is that the one that Runnings sells?
Maybe they could help.
My sympathies. The new ones come with the permanent oil pump.
The older ones, seemed like a PITA. I know the small is $3500, medium- around 5K. Plus, 2 months fulfillment time on the freeze dryers.
I know people who freeze dry casseroles, meatloaf, yogurt, cheese, fruit. They think they are awesome appliances.
Out of my budget. With your huge investment, I hope you get the help you need to repair it.
