Our old vacuum sealer finally gave up on me. The heating element had gotten wet or corroded and eventually burned holes through the Teflon sealing strip. We use this quite often and I needed a working one, but a new $100+ sealer was out of my budget range.
A quick search revealed that it is very common for the sealing strips to wear out, and replacement parts are readily available. The whole process of replacement should take about $15 and 15 minutes of your time. Step-by-Step after the jump.
