This is good advice, but Dometic recommends the fans be below the coiled tube, blowing up. A fan on the inside helps as well.

I did a few things that seem to have helped my old fridge preform a bit better in hot weather.

Open up the bottom outside vent a little and leave it open.
Added a simple fan to the outside control area that blows up over the coils.
Clean out the stack (don't think that had been done in the first 16 years of the fridges life).
Added foil/bubble insulation all the way around the fridge.
Closed off all the small gaps between the main fridge and the rear outside control compartment as well as the cabinets that surround it.

Last but not least and the item I think had the biggest impact. Purchased a good portable cooler for holding the items that satisfy my thirst quenching needs. Resulted in far fewer reasons to keep opening and closing the fridge in warm weather.

Norcold Recall


But recalls that aren't done isn't an indication of overall danger on the other 99% of LP refrigerators.

In the case of the mentioned Dometic fire, it was an engineering problem. BTW: Apparently the owner was leaving it running and unattended for at least weeks at a time, not recommended by anyone for an RV LP refrigerator.

And forgetting to turn off your refrigerator before pulling into a gas station is an example of operator error, not an intrinsic danger of LP refrigerators.

Everything about an RV can be dangerous if not maintained and used properly. Years ago there was a story about an owner loosing a finger when the toilet valve snapped shut on him.

Danger, Danger, Everywhere

The fridge fire linked to earlier was in a fridge covered by a recall that had nothing whatever to do with LP operation, and the cause was likely related to the defect targeted.

That (ongoing) recall very specifically addresses problems that can, will, and have caused fires during or immediately after operation on 110/120v. It's an electrical problem, unrelated to propane operation at all. This defect is the cause of nearly all reported RV fridge fires in recent years.

That recall began with the models named in the below quote, taken from page bottom at this link. It has since been expanded to include many more Norcold models with the same shorepower related defect:
If a leak occurs, the cooling performance of the refrigerator will deteriorate, requiring immediate replacement of the cooling unit. Extended operation of a leaking cooling unit in the AC electric mode can result in a fire.
