Smelly RV propane detector

after a heavy rain this week, I detected a funny smell that seems to be coming from my propane detector.

Is it a musty smell? How long after the rain?

I'd search for damp/wet musty or molded wood.

I can't think of a reason, aside from possible burnt electronics smell if something broke, that a smell would come from the propane detector. I suppose its possible an electrolytic capacitor in the propane detector could have ruptured and could theoretically emit a smell.

It shouldn't take much effort to remove the propane detector and check it out outside the RV. As others have already indicated, if its the original detector, it should be replaced anyway.
