Baffling Fridge Problem Baffled!

The last year or so, I started getting flame-out while running fridge on propane while towing. Pissed me off cuz it always works perfect when standing still and it is the cleanest propane delivery system on the planet. Something changed with solenoid or draft or karma or wind direction. Don't know what. I was able to run on 12 volt while towing and added a solar panel to my TV to help out so I didn't let it bother me too much. But...being the OCD camper that I am I still wanted to run fridge reliably on propane while towing. Just cuz!!

I can't remember or find where I found this baffle design (I would offer credit), but, hot damn! it works great!! I made mine out of some leftover round ducting I had sitting around. It's really cheap, works great, I swear the fridge works better and it is a work of art!! And please don't call me Art.

The cut size in 8"x10". The cutout is 1 1/2" from bottom, then another 2 1/2" and 2 1/2" deep. Snaps right in. I cut a little tab to secure it a little better. I doesn't get too hot to worry about and works for me. I did re-locate the 12 volt line so no chance of chafe.

Just another Dometic fridge art project!!

Doodie!! Everybody out of the pool!! 

Couple of reasons why I prefer fridge on propane...

1) Mine appears to work better on propane.

2) My TV charging system cannot really keep up the 10 amp drain the fridge takes. I would rather use those amps to go back in batteries between boondocking sites.

3) It just pissed me off cuz it was never an issue until it was.

Until recently, running on 12V was not an option. The Frontier (and the Escape before that) simply could not provide enough power through the connector to both charge the dual 6V batteries I had previously, and was unsuitable for the LiFePO4 battery I have now. I added a battery isolator and ran a separate 121V circuit to power a DC to DC charger for the LiFePO4 battery. That circuit, coupled with the stronger DC to DC charger now means that I can both charge the battery and run the refrigerator on 12V simultaneously. However, when stopped, the refrigerator still needs to be on either AC power or on LP.

Before making the changes, I towed for thousands of miles while running on LP gas with no problems. I added screens to the refrigerator vents. These were to keep the wasps and other insects out. An added advantage is that screens act as a flame arrestor. I learned about that in science class many years ago. Place a screen above a Bunsen burner and the flame halts at the screen. I have felt safe while towing and even when stopping to fill the gas tank.
