FoodSaver Fails to Seal Bag

PROBLEM: FoodSaver fails to shut off and seal bag. After investigating this problem on two different models (V835 and Compact II), the problem was found to be that the vacuum pump was no longer able to produce a hard enough vacuum to trigger the sensor which initiates the heating strip which seals the bag.


SOLUTION: Replace entire unit. Do not waste your time or money buying a new heating strip, which is one of few replacement parts offered.

FoodSaver's infamous for a product that works great at first then slowly starts to fall apart. #1 problem's the gaskets, hands down. The gaskets dry out, some faster than others depending on use/care. Then the unit won't remove all the air or seal properly. FoodSaver doesn't care: they want you to'upgrade'.

Here's how to restore your unit to like-new: soak the gaskets in very warm water to restore flexibility. Air dry (not over 24 hrs). Then coat the gaskets (both sides) with FOOD grade silicone grease (available through Ace Hardware... they'll order it if out of stock). Return gasket to machine.


Poof! It's good as new. As soon as you notice the surface changing, or every 3 months re-coat the gasket. You shouldn't have to soak it if you haven't waited too long.

I just hurled mine in the trash. I know this is an old thread, but for newbies; use the straw method! My FS ALWAYS had an issue. I couldn't use it free and clear one time! Clean this or that. The hooks to open the thing stopped opening unless I used scissors or butter knife to "push" it open. Bag is too big, too small. It just randomly worked and half the time I couldn't figure out what I did to make it work! I've only had it a couple months. It looked beautiful. Big, upright streamlined. But not worth the money! It's probably vacuumed and sealed 20 bags of food.
