Foodsaver v3820 will not vacuum the air out. We have cleaned it and out the bag in curling down and still does not vacuum?

SOURCE: My Foodsaver Vac 1050 doesn't extract all of the air from the bag

Either the sealing strips are dirty letting air escape or the lips of the bag are turned upwards. Push the front of the bag down towards the bottm chanel and it should work fine. I have had one for eight years now and love it.Ken Vancouver BC

This is likely happening because the unit cannot detect that a vacuum has formed, and because of this, the unit will not seal the bags, with the gaskets around the vacuum channel being the probable culprit. The Foodsaver gaskets will deform and/or dry out with time, just like in any device, but you don't necessarily have to replace them. I've tried this inexpensive solution on my own Foodsaver V2490, and it works perfectly.
Buy some food-grade silicone grease and apply it to both the upper and lower gaskets. I remove the gaskets and coat both sides with a thin layer of grease before replacing them in their respective channels. And since this grease will be absorbed and/or dry out with time, you will have to do this occasionally, so I also flip the gaskets (i.e. turn them over) whenever I apply the grease.
You can buy a 2 oz container of silicone grease at any dive store, or you can buy it over the Internet by searching for "Trident silicone grease".
This is a link where you can buy it for around $7.00:
Dolphin Dive Center
I do not work at this dive center, but I am a scuba diver and already had some grease that I use for the numerous rubber gaskets in my gear. The 2 oz. jar will last you several years, and you will find many other uses for it around the house since the grease will last longer than a spray.

This is likely happening because the unit cannot detect that a vacuum has formed, and as a result, the unit never "turns on" the heating element to seal the bag, with the gaskets around the vacuum channel being the probable culprit.
