Two story Foyer Chandelier: one switch intermittent.

I suppose there is something simple about this but beyond my understanding.

We have two on/off switches (up and downstairs) for this chandelier. Recently, one of those switches (downstairs) has started acting up. There is no response to on/off action until the switch upstairs is switched on/off. This is not reproducible all the time. Any suggestions?

You have two 3-way switches and one is obviously going bad. I'd replace both of them. I would suggest using lighted 3-way switches.

If this previously worked fine the switch sounds like it is failing as was mentioned. If it never worked properly one or both of the switches are improperly wired.

When you replace the switch, pay attention to the wire that is on the odd colored screw.

Before taking anything apart, make a note of which wire was connected where.

Save the old switches until you are done.

Three way switches have 3 terminals (or a fourth green terminal for the bare ground wire). Note if one terminal (not counting the ground) is stained darker or has the letter C or "common" engraved on the switch body near it. The wire from that terminal goes on the similarly stained terminal on the new switch. It doesn't matter which way the other two (non-ground) wires are connected.
