It would be useful to be able to (easily) smell a refrigerant leak, too.

  That smell you're thinking of is an additive - propane and butane are relatively odorless without it.

    Yeah - mercaptan I believe? I knew that, I guess I just assumed they wouldn't use a non-odorized propane..

      https://en.wikipedia.org/wiki/Tert-Butylthiol https://en.wikipedia.org/wiki/Tert-Butylthiol - Because propane is delivered as a liquid and vaporizes to gas when it is delivered to the appliance, the vapor liquid equilibrium would substantially reduce the amount of odorant blend in the vapor. https://en.wikipedia.org/wiki/Ethanethiol https://en.wikipedia.org/wiki/Ethanethiol is used for propane (usually) but for the small amounts in a recirculating setup they may skip it.
