Judy, look for charred glass or broken filaments. Pull it out from the socket, and look inside the glass for black marks or a broken filament wire. If you have W-3 plug fuse, if yours does not have a clear top, there will be an indicator, a little tiny piece that pops up if it's blown. If you have a different model other than the W-3 let me know and i can try to help you.
