Harvest Right Vacuum Fix VIDEO

A GREAT fix to your HR Freeze Dryer Vacuum Leaks. We cover a lot of problem areas.
My apologies for the video, it has been a long time since I have made one. The content is great though and the fixes are real. Post your results and comments, the good, the bad and the ugly. THANK YOU!

Hands down the best video to stop leaks. I have looked for the details listed here for 6 months. I asked Donald how to fix the issue on a live show. He refused me to his video fix but it lacks much needed info and is not nearly as in depth. Thank you so much for this.

Seriously they built the tray assembly so it hits the door gasket? I don't understand how such an expensive machine could have a problem like that.

I have done every single thing you have mentioned to do in a repair for my freeze dryer. In the past when my freeze dryer was working fine. Then There was an issue where I had to send my freeze dryer in for repair. After it was returned to me I couldn’t keep a vacuum every so often, and I would crank my valve as hard as I could shut, and then it would finish the batch. Little by little, it became more and more frequent that I could not keep vacuum. That’s when I ordered a new valve from Harvest Right, installed it and nothing changed. I couldn’t keep a vacuum. My vacuum pump stayed home while it had repairs. I have changed the valve to a gas valve. I have used the liquid tape and the stretchy tape you recommended and used the that you recommended. Also check the door the tray inside the freeze dryer for adequate space. The only thing I haven’t done is adjust the door and I don’t think it’s necessary because it looks like I have a seal around the ring. Does that make any sense?what would you do if you were me.😢 I have a no oil pump . I will do a full freeze dried bread test. Just in case you’re tired of answering these questions.

I want to thank for for this video. We had tried multiple things to fix our $4000 paperweight with no resolve. There were vacuum leaks that even harvest right was zero help in resolving. We just put only the liquid sealer on all the joints you specified and turned on the pump and after about an hour we have finally reached 450 mtor and slowly going lower. We couldn't get the freeze dryer anywhere close to 500 before we followed your video. You sir are awesome!

Excellent video! I need to do this to my freeze dryer just to prevent issues. Do you suggest taking all the areas loose and taking off the teflon tape that is there from Harvest Right or just putting the liquid tape over it?

[@rossim2005]

Thanks! It worked! Back down to 230mTorr. Had an issue getting below 1300. Bought a new stop valve, put on nylog blue, put liquid tape at all the points you said to, and will finish it off with stretch and Seal tape.

This may be the most helpful and easy to follow vacuum fix video. I've watched many including several FLX fix vids. I bought the white liquid tape from a local Menards, which makes it easier to see where you might have pinhole leaks after a first coat. The black liquid tape may camouflage holes/gaps. Thank you for taking the time to share the video!

Thank You!!! We purchased our FD machine 16 mo. ago. Mtorr's rarely got below 200 mtorr's, averaging around 210-220 mtorr's. After applying this fix & wrapped foil around the tray holder (wrapping the tray holder was found in another video) . Knowing the tray holder is shielded a little more from the iced tank walls, I also lowered the drying to 120 deg. as often the drying hits up to 131 deg. and I've heard 125 deg is when food starts to cook. Now we average 142-156 mtorr's. Thank you AGAIN! I've been hearing people putting food grade Super Lube grease into the door gasket slot for more sealing power, some mentioning their machine got below 100 mtorr's.

I have no problems with the Harvest Right machine love it I had a problem with the vacuum adjusted the door and new valve it works good now

[@danielpittman2188]

Our machine is not giving frost rings or freezing and can not find videos to help us diagnose this issue.

[@genesisfarmhomestead2017]

Great video

[@genesisfarmhomestead2017]

What is the name of that tape and where can I find it?

[@baaboo21]

Not getting an error, the pressure is just not dropping below 500, so all long batches are being ruined.

[@MsCindyh]

Thanks, have everything ordered. Will be working on it as soon as the supplies arrive. My error said not vacuuming …but also said In a later message that the sensor may be bad. Trying this first.

[@lindam7584]

Excellent video. Wish I found you months ago. I am trying everything you suggested using the same product suggested. Running my FD now for 24 hours and see what happens! Thanks sooooo much

[@-Tetragrammaton]

Awesome Thank you!!!

I know what you mean. Too bad that the pump manufacturers have to be so secretive about their lubricant design criteria.

[@dancnbear]

Steve, which pumps are you using? I was just about to retire our standard pump and purchase a Premier XL from Harvest Right or maybe Navac 12-CFM, but I'm researching any and all pump option. Any suggestions?

[@dancnbear]

I'm running the original Harvest Right Standard for now. I've got less than 80 batches on it. I may have to hook up my secret weapon.
