Question about Heating & Cooling
The heating strip on my foodsaver does not work, the pump is working ok but the heating strip does not heat to seal bags
My machine stopped working because the sealing ribbon was broken and the tape was worn. FoodSaver no longer does repairs. I knew the wire was called nichcome ribbon so I searched that. I checked the resistance of the ribbon on my machine, it was about 3.8 ohms. I found a site called mpakonline.com and from their site I bought 1/16 x .005 nichrome ribbon and 3/8 x 5 MIL. x 18 YD Acrylic Teflon Tape. The total cost of these items was about $36.00, the ohm value of their ribbon was 1.66 somewhat less.I used ends from radio shack made the repair and it has been working fine for the last two months and I have enough material leftover for about ten more repairs.

My unit also had a few pinholes in the sealing tape. I thought I needed some new tape, but solved the problem with no new parts! You need to take the unit apart by removing all the screws on the bottom (there are a bunch of them!) to expose the underside of the sealer. There are 2 screws that hold the sealing strip in place. Remove the screws so you can clean the strip and the area under it. I must have gotten something under the tape that got hot and burned several pinholes in the tape. Then carefully remove the sealing tape. Once all parts are clean, re-install the metal sealing strip. If your tape is like mine, all the pinholes are in the middle of the tape, but the tape is wide enough that you can re-use the tape by locating the heat strip in the top half of the tape. I simply used some scotch tape to hold the heat tape in the new location ond my seals are good as new!! My unit has been been working well for about 5 years, so this arrangement should give me 5 more. Then I will move the tape again for the next 5 years!!

I got tricked into buying an old foodsaver on craigslist.. the seller had said that the machine was working perfectly. It was not... The sealing strip had bubbles in it and so it wouldn't make a tight seal on the bags.
I managed to fix the problem by rubbing a q-tip with alcohol on the strip. I then used a blow-dryer to and heated the sealing strip on low. I noticed that the bubbles shrank and eventually disappeared. I'm not sure whether or not the rubbing alcohol does anything (it probably doesn't) but using that method, I was able to reuse this old foodsaver.
Hope it helps!

My food saver is about 10 years old. Once replaced by repair about 8 years ago. Today it wouldn't seal. There was no heat and I thought it was kapoot! But my friend and I read one of the posts and lifted up the strip and cleaned it and the rubber sealer. Also just used a sponge and it works now. Before giving up or taking anything apart, just make sure that the seal and strip are free of any tiny specks that might get in the way of the strip's working.

Hello, My unit had the same problem and I had to take the back off and found the thermal switch (which has 1 red wire in and 1 red wire out) was not making contact. I cleaned the contacts and made a slight bend adjustment and the unit works just like new. Hope this helps.

I DON'T BELIEVE ITS THE HEAT STRIP, I FLIPPED THE SEAL ON THE INTERNAL VACCUME PUMP AND IT WORKS JUST FINE. THE PUMP HAS TO REACH A CERTAIN PRESSURE TO TRIGGER THE HEAT STRIP TO COME ON.

I had the same issue with the thermal seal not working. If the unit does not create a vacuum the thermal system will not work. Inside the handle you will find the upper section of the sealing device. It has a flat black rubber strip. It is heal in place with three (3) phillips head screws. Remove the the screws and the face plate will come off very easy. Take a look at the back side of the plate in particular the three areas where the screws go. You will probably notice one or more of the little spacers have cracked or has a crack. This stops the unit from creating a vacuum. Take Super Glue and form a small ring of glue around each of the broken pieces. I also place a ring of glue around the one that wasn't cracked. After the glue dries, reset the upper vacuum chamber by placing the three screws (CAREFULLY not to re-damage the chamber). After you replace the top chamber you can also fill around the phillips head screws with more Super Glue to ensure air will not escape. Your unit should work like new. Good luck.

I have a Foodsaver v2490 that stooped sealing. I lifted the strip and cleaned and cemented the rubber sealer using pvc cement. I cleaned the metal element, rubber seal and element housing with denatured alcohol. It worked and my foodsaver v2490 seals again.

Food saver wouldn't seal. I just cleaned the heat strip with 99% isopropanol (rubbing alcohol) . It worked!! Vacuum sealed the bag perfectly! I did also press and hold the vac sealer down fairly hard during and after it finish sealing. Hope this helps!!
