The motor sounds great, but nothing else is happening. Last week it vacuumed , but would not ever stop and seal....I'm wondering if it just needs a couple of new foam gaskets?
Thanks.
You need new replacement gasket, to get one, visit amazon FoodSaver Vacuum Sealer Upper Gasket Assembly T910 00075. I hope this was helpful. cheers

If your FoodSaver is more than a couple years old, the gaskets have probably gotten compressed. Especially if you use it often or store it with the lid in "latched" position.
FoodSaver's website has replacement gaskets, $3 each, but it's hard to match the right gasket with the V2440. I called and got confirmation: it's this one. http://www.foodsaver.com/Product.aspx?id=r&cid=0&pid=294
Same gasket, upper and lower, even though it's listed as "Upper" on the Web page. You can also call them at 877-777-8042 and order Part # T910-00075.
Meanwhile, I've had good luck with soaking the old gaskets in warm water for a few minutes, then letting them air-dry. It seems to restore their sealing power for a day or two at most, but that's enough for me to vac up my weekly freezer groceries.

Take your seals out.
Rinse.
Ring excess water out.
Put moist seals in place.
VACUUM HAS RETURNED!
I held gasket over steam. Compressed areas expanded restoring gasket to original condition. Problem solved. Be careful, steam burns! Do not to put hands directly over steam. Tea kettle works well for this.
My foodsaver was leaking through the attachment port for the jar sealer. If you hold your finger over that port it would vacuum good. It seems like the ball check valve is leaking.
You should NEVER have to replace your gaskets if you maintain them every few years with food-grade silicone grease. See my post below from 2010. Water will dry out quickly - grease will last for years!

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.
The Silicone Grease worked great for me. I picked it up from Amazon for about $8.
My Foodsaver vacuumed fine, but would never seal. I found that if I pushed really hard on the cover, it sometimes worked. Then I found this Fixya forum, bought the grease, and lathered up the bottom and top gaskets. My foodsaver is working as good as new. I don't know how long the grease will last on the gasket, but the 5 minutes it takes to apply it won't be a problem in the future.
Thanks to all that posted here!
Is the vacuum pump motor working when you close the lid and select a VACUUM option? If not, there is a warning in the Foodsaver's documentation about not getting liquid sucked into the device? If the vacuum pump is active but not vacuuming, then your seals are likely faulty.
Here it is 2017 and I just had to re-grease my Foodsaver's gaskets again as they had dried out after about 3 years. My Foodsaver is now working as good as new again, and it is now over 10 years old.

The phone # listed for Jarden still is valid, was able to get the upper and lower gaskets for my V2440 Food Saver from them. Thanks for the info.
Instead of silicon grease you can just use vegetable glycerin. You can get it in almost any supermarket for a couple of bucks. I actually just use the Rosewater & Glycerin that I have on hand. It's nice since it just feels like water but has the glycerin in it that preserves the gaskets. Fixes the issue for a couple of months at a time, even in the desert conditions I live in.
The application of food grade silicone grease will last for a couple of years because it does not evaporate like a water and glycerin solution. And silicone grease can be used everywhere around the house, like faucet and hose o-rings.
I just re-greased my gaskets with food-grade silicone grease after 3 years! I now have a brand new unit that is actually over 10 years old.

The pumps do wear out. But its not the piston. It's the reed valve. It gets compressed for so long the reeds stay open.
Mine may have (months ago) gotten some water in it. Could thishave stopped it from working?
I seriously thought the pump had just gotten worn out because of a lot of use. I greased the gaskets and it works like new again. Thank you for the advice. It saved me from having to buy a new one!

WOULD NOT VACUUM THE BAG
Mine vacuums sometimes for an extended period of time and then seals, sometimes it just vaccums and doesn't seal. I took the foam seal out and turned it around and it seems to help somewhat.
I have the same problem on an older one (VAC 800) and it's definitely the gasket on mine. I pulled it out and it was warped in a few places. My only problem is finding one now!
If there is any sort of wrinkle in that open edge it won't stop sealing, or is even a slight bit of whatever you are sealing is over that top edge it won't work either.
Vacuum motor only hums/no sucking, remaining on first indicator light only, does not progress nor seals. Seals only if manually activated. Already tried soaking/moistening lower gasket with no results. Was a real workhorse until 2014. Thanks
See my comment below on lubricating both the upper and lower gaskets with food-grade silicone grease.
