Hi, have a workhorse 2300 that just stop sealing after a solid 10:years of use. The vacuum part of the sealing process works fine, but the bags won’t seal. I examined the element, which looks fine. i went ahead and replaced it, but still no sealing function. Any ideas on what component may have failed?
Any ideas on what component may have failed?
I say the first thing is to decide if it's a leak down or not heating the sealing bar .
Like Charlie said is it a different bag ? What mil bags do you have ?
I have an Inkbird that won't seal the heavier mil bags .

I'm not familiar with that sealer , but had the same trouble with a Game saver deluxe .
After the vacuum is drawn , there is a valve that should close to keep the suction in the bag , then the bar is heated to seal it shut .
If you got moisture or a spec of something on the seat of that valve it will leak down before it seals .
I looked at the Weston exploded parts diagram. Could be the transformer, circuit board (expensive) or the limiter switch (possibly).
Good luck figuring it out.
I bought a LEM chamber vacuum sealer from Costco last year and haven't used my 2300 since then. But am keeping the 2300 for wider items.

Hello and thanks for all the helpful information. I am using the food saver bags.

Smooth side: 3mils thick
Textured side: 11.5mils thick

i picked up a Foodsaver 5200 to take care of the remaining meat left over when the 2300:quit working. I wasn’t impressed. Looks so fragile and the suction is not as good as the 2300. I noticed the Costco chamber sealer and I am giving that some consideration.

In the mean time I will tinker with the 2300. I will not be surprised if it is the circuit board, but hope not😀.
