Well that's an unusual intro post. But why not.
First check the sealer bar for continuity. It's a resistive load so it will get hot. Don't recall what it should read but it should not be open.
Somewhere in the archives I had mine disassembled when someone (Wildboar?) was asking same question. I took some pics and posted them but could not find the thread.
Anyway it's pretty straightforward. (But I'm going from memory and a quick look at mine) Remove the sealer bar. Remove the lid from the arms - this may be an unnecessary step but I remember doing it. The bottom of the sealer compartment will lift off the frame after 4(?) screws are removed from the right and left sides - up at the lip.
VM customer service was top notch when I did mine.
This is thread where it was discussed.
