Smoke from lower fridge (Dometic 3 way) compartment

Likely the sizzling was water hitting the very hot evaporator section of the ammonia unit

IDK, there was also smoke and that distinctive smell of burning electrical insulation.  Should the ammonia unit be hot if the fridge isn't operating?  Yes there was DC power in that area, but the fridge was off, I would think the ammonia unit wouldn't be hot?  But, yes, I'm glad to be getting it checked out.

I went back and re-read this whole thread again but I'm missing where she said anything about washing her trailer with a pressure washer. Was something deleted before I read this thread?

That was my assumption,  as I  have never had an issue with water getting into the vent while washing with a bucket and soft brush. We rarely  use a spray nozzle on the hose, at least not around vents.

Sorry for the misunderstanding,  Liana.

Please keep us posted on what you find.

Well - 

the smoke and the smell are a good indication that the ammonia "unit" had nothing to do with the issue at hand.  

Yes, the ammonia "unit" could still be hot even with the fridge off, but, it shouldn't be hot too long after the fridge is off.  Certainly, after an hour or so, I wouldn't think that it would be so hot as to cause the sizzling you heard.

Yes, as you have already decided, in cases like this it is always better to get things checked out.  Otherwise, you will pay the price of constantly worrying that the problem will reoccur or worse.

If you want to continue to contribute to the forum with comments or to answer questions, please do it without your usual negativity toward Oliver. This time, I'm not asking.

Certainly this is a possibility, but, when it was said that the fridge was turned off and then retried a bit later and the sizzling was still heard, I assumed that any water in the area you mention would have been evaporated the first time.

 

Most likely as you stated.  But, maybe not.  When in troubleshooting mode, between Muphy's law and my spelling of "ASS-U- and Me" I try as best as I can to avoid both.  🙂     

But, as you stated the odds are that it likely would have evaporated.  More likely water got into the control board at the same time as on the heat exchanger.  Water on the control board area would generally result in a unit failure.  But then, I'm now making ASSUME's too.
