All,
If you're serious about desoldering things, the tool to have is the
"Edsyn Soldapult". You heat the joint with your soldering iron - when it
melts, you plop the tip of the soldapult right on it, push the button, and
*WHAM* - clean joint.
I have desoldered thousands of joints with those things, and IMHO there is
nothing better. Get the real one, not a knockoff.

Chuck,
From the symptoms you describe, I would start with replacing K1. The
fact that tapping on it allows it to reset suggests it is a mechanical
issue.
I found a sucking desoldering tool that worked great for the 2 v4
relay sets (6 total) that I needed to replace for the harmonic
suppression fix. This is the tool that I found to work the best:
The thing is to compress the bulb before applying it to the pin and
pad, let set for a few seconds then release the bulb. It took two or
three times on each pin to clear out the solder enough to free the
pin. I clear the tool by pumping the bulb over a cardboard box to
catch the removed solder. There were no board tabs damaged.
