  Ronald HarrisAug 1, 2025
  If your PROMARKS Food Saver isn't sealing properly, several factors could be responsible. The sealing wire might be broken or loose, requiring replacement or tightening. The pressure could be insufficient, or the sealing transformer defective, both necessitating replacement. Damaged Teflon tape or silicone rubber also require replacement. If the sealing and cooling times are too short, adjust them to the proper duration. A defective pressure bar or bladder bag also need replacement.
