Fridge Defend Install

I installed my Fridge Defend yesterday. It took me most of the day by the time I did my best to digest the multiple documents, web searches and video's recommended by the ARPRV website. It was not difficult just took some time. I would not recommend anyone attempt the installation that does not have a basic understanding of electronics. The one thing I was worried about going in was installing the boiler sensor and that turned out to be simple.
I had an issue with the fan not coming on, even though the top section of the cabinet was very hot. I did find the fan test so I know they work but could not find the set point for the fan temperature control. I emailed Paul and this is the response I got "Hi Bruce, sounds like you need to download the manuals" which I had done and read through a couple of times before and during installation. Now I am the first to admit that I may not be the sharpest knife in the drawer which is why I felt the need to ask for help but that response was uncalled for. I have not given up and will post updates as I progress.
One thing I noticed on my Thor Hurricane is that there is a 5” high by the width and depth of the refrigerator dead space above my fridge that is nothing but a heat trap so I filled the empty space with fiberglass insulation and that seemed to help the heat transfer from the top of the fridge into the RV living space. The sides were insulated but not the top so much of the heat was escaping into the living space rather than out the vent.
If someone knows how to change the temperature for the fans will you, please post a reply or PM me?

I’m still needing to get back to mine. Need a day without rain and they seem to be pretty rare this spring. The web site has TONS of information but it’s not well organized nor is the navigation intuitive. I did stumble on to a page about setting the fan temperature switch but I just looked for it again and didn’t locate it! It’s there though and if I can ferret it out I’ll be sure to print out a copy. Good luck. Supposed to be nice later this week so I hope to finish mine up.

Found it! There may be other navigation maps to get to the page but I got there on the “purchase” page. Got to any product that has the fans, click on “additional product information” then took for additional fan installation details and go there. In the meantime maybe this screenshot is what you need. Good luck!Click image for larger version

Thank you Pete'sMH, that is perfect. I did find a page and short video but that one talked about changing parameters in the firmware and had links that would take you around in circles. I think I can set it with the information you found.
Thanks Again Pete.

Did you figure it out? I finished my installation yesterday except for the outside fan. I want to fabricate a bracket to hold it in the opening instead of attaching it to the cover. My system works great but, like yours, did not get hot enough to turn on the fans in the default setting. I reset mine to setting 2 and they seem to be fine. My boiler reads about 190 on gas and my fan temp sender runs about 125. Fun project with, potentially, life saving benefit.
