Further investigation with an IR-sensitive camera revealed that it was in fact generating light, but it looked fairly weak. Just in case it was simply dirty, I figured out how to disassemble the emitter portion, gave it a very good cleaning, and tried again... this time, it worked. So, problem solved!
