New CHE making noise

I just got a new CHE, a different brand than I'd used before. I hooked it up to the thermostat and everything is good, but when I turned it on, I heard a clicking/ticking/cracking sound.

I asked my electrician friend and he said it's probably harmless, just the bulb expanding as it heats up. So I turned it back on and it hasn't made any noise since (about an hour ago).

I've never heard a CHE make noise before, but it also turns out I was using a not-super-great brand (exoterra), which is why I got a different one. Have any of you ever experienced this with a new CHE? Have you ever had one that made noise when you first turned it on?

My new ones always do that. Even give off a little bit of a chemical burning smell. They stop doing that eventually. :)

Okay thank freaking gawd. I'm familiar with the odd smell, but never had one make noise before, and it freaked me out. Thank you!
