What's normal for Dometic Fridge smell outside?

[Vista]

Brand new RVer. Did a test run this weekend and have just a few questions, This is about the little fridge...

New to me hardly used 2019 175RD unit with a propane/electric Dometic fridge.

Cooled fine just on shore power on AUTO with no propane.

Switched it to propane this morning to test the propane system out. Seemed to still cool ok. No smells in the trailer, but outside there was a faint "hot metal" smell. I would not describe it as a propane smell. Is this normal? Shouldn't a one year old fridge be burned in already, even if the PO only used it a few times?

I did pop off both top and bottom exterior vents and I could not see anything that looked out of sorts, although I don't know what I would be looking for.

Thanks for any help.

If you don't see any smoke I would think that the smell will go away with use.

Thanks. It was on propane for a couple hours, no smoke.

As long as it’s not an ammonia smell, that indicates a refrigerant leak.

Thanks guys. Not ammonia. Also not un-ignited propane.

It smelled like ignited fuel or heating metal - typical of hot oils or metallics. I will keep an eye on it. Or a nose.

Vista - our 195RB has the same fridge. The smell on propane, IMHO is heat related and is similar to the smell from a heat sink on an amplifier or similar type of unit.

Should not be a problem.

I installed a cable hook up in the top vent cover so i smell it each time we set up and tear down.
