Narrative:

We were climbing towards blythe VOR en route to phx. We had been climbing unrestr to FL190. I was the PNF and was doing paper work when the captain commented we had gone past our altitude to about FL196. We descended back to FL190 and at no time did we get our altitude alert horn. We should get a horn 1000 ft prior to an altitude at our assigned altitude. Nothing was said by ATC. The altitude alert horn did not work for the remainder of the leg. We discussed it among ourselves and determined we were dependent on the altitude horn. So when it didn't work, we never noticed.
