  If your PROMARKS Kitchen Appliances unit isn't sealing properly, several factors could be at play. It might be due to a broken or loose sealing wire, in which case you should replace or tighten it. Insufficient pressure could be the issue; if the pressure bar is damaged, replace it. Other potential culprits include a damaged sealing transformer, Teflon tape, or silicone rubber, all of which would need replacing. Make sure that you adjust to the proper sealing and cooling time, and if the sealing pressure is too low, replace the pressure bag.
