I could mount the fan on the inside of the vent cover, do you have a thought on whether that would increase or decrease the amount of air moved out of the cabinet? There's not much room between the vent and the back of the fridge.

I've run fans on many fridges over the years-  never mounted one outside though- I like it inside the panel out of sight and out of the weather. 
12V computer fans work great- I usually use a pair with an mechanical thermostat so no power is drawn when cooling isn't needed.

They are mostly needed because many RV builders do NOT follow the fridge makers instruction on proper installation as to baffling and airflow.   
The fridge installs with the upper vent in the wall rather than in the roof usually perform worse and benefit from fans the most.

Very clever! Replacing the entire vent cover with a fan unit is something I never thought of.

I installed this Valterra fan and have used it for 2 years. I have no data on increased efficiency, but it helps me think I'm improving efficiency whenever I hear its gentle hum as a walk around the back of the camper outside  8)

This is mounted inside the external fridge compartment on an existing bracket about halfway between the upper and lower coils. It definitely improves air flow when the included thermostat turns it on. I hardwired it into the 12V available in the compartment.

Hello,

Have a look at the products from arprv.com , they provide fridge protection devices along with a single or dual fan ventilation systems.

Cheers!

Hey David,

Yes you are correct about installing the modified panel after arrival.  In my configuration since I'm using a separate power supply I'd have to manage the wires plus the fan itself isn't really an outdoor type of fan so if I were to hit some wet weather during travel it could be damaging. Everything is pretty secure so it's more about the electronics than the danger of it falling off.

With respect to the thermostat, I had it and it's cheap as sin so I used it rather then tie into something in the trailer itself.  Plus, while the draw of the fan is only .25 amps that's 6 amps over the course of the day and I boondock medium to long periods of time so battery is a consideration.  I could tap the fridges 12 volt source, it's right there and I might in the future but for the moment I prefer using a different power source.

MitchB:

While I have never had a problem with fridge cooling in our NE US climate, I am intrigued by your design. Some questions:

I assume that the spare Dometic panel is so that when you reach your destination you can pull off the existing panel and replace it with this one with the fan and controls, right?'

Why don't you want it on when traveling?

Why do need a thermostat? These small DC fans draw very little current so you could just power it from a switched source in the fridge and leave it on all of the time.  Or you might be able to find a DC source in the fridge that is thermostatically switched to power it with. Maybe the burner solenoid valve for LPG use or an AC relay for AC use or both with a couple of diodes.

I know hot weather cooling of the fridge can be difficult so I've modded an upper vent panel to include a fan and a thermostat.  I'm hopeful that when the back of the fridge cabinet gets hot the additional airflow will cool it enough to allow better heat transfer though the outer coils. For power I'm running it to a portable battery box I use but there is an easy tap in to 12 volts right at the base of the fridge.  From a parts perspective this thing is pretty cheap to build, a Dometic vent panel for $25 (don't want the fan stuff on while traveling), a thermostat controller for $7 and the weatherproof box for the thermostat $22.  If anyone is interested I'll link the parts on Amazon.

Ok, thanks for that information Merlin.


Great information, thanks for sharing.  Can anyone suggest a good surge suppressor please.

I use and like this one

A much less expensive plug in version is also available.

There are good write ups on here about installing one.

Back at the pedestal, the 30 amp plug was not fully seated. Doh !





My last trip where I had hookups, a rarity for us, - the 30A receptacle was just plain worn out- very loose fit with crackling and arcing.
Luckily I carry a 30-50 adapter I've never used.   
Used it to get a good connection to the pedestal. 
Reported the bad receptacle to the host upon leaving...no idea if they addressed it.

I had that the very first time we used our “free” Thousand Trails membership when we got the trailer. Arcing. Pedestal. Rain.

Needless to say, we passed on renewing.
