I have a very large chest freezer, possibly around 25cf (really big) that
is not staying open. When I tighten the springs it will stay up, but also
will not close. My guess is that the springs are weak and need replacing.
Does this sound right to you? One side of the lid is also bent at the
hinge and the hinge is pulling the lid back from the edge. Could this be
the problem instead?
