Thanks William,

This is the sensor on the expansion tank, right? It's attached to the tank
still. Could it have been disconnected at another spot? I would like to
re-connect it and see if that light still likes to flash.

Also, not sure if I have the right cap on the expansion tank. It doesn't look
like it has any kind of pressure releasing mechanism. Should I see one? It is
blue plastic, made in Germany and says "Blair" on it. Don't see a part # on it,
but I haven't taken it off. Still worried about adding air to the system by
removing cap. Are these fears unfounded?

Peace - donna
