It lasted (7) years!

Question about refrigerator thermostat and these fans. It is my understanding that the thermostat sliding adjustment lever works by placing the pickup sensor bulb higher or lower. This height difference places the bulb in warmer air if slid upwards or slightly lower temperatures if slid down. This relies on the sitting air in the fridge being warmer up higher and cooler as you go down. So if you install a circulating fan it has to even out the thermo layers in the fridge therefore making the bulb position ineffective. It appears to work for everyone, just wonder if you still have temperature control or doesn't it matter since with the fan running the fridge temps are what they should be anyway. Feedback?

The sensor works by conduction with the fin, not convection of the air.

When I factor in gas and local tax, it isn't worth my time and energy trying to save a couple $$. Factor the cost over 7 years even makes it less appealing. I've been a MacGyver my whole life and have found there are some things not worth the time to MacGyver. If a person can afford an expensive RV, they should be able to afford $23.06 for a nice dual cooling fan. That's barely 50 miles of traveling at the price of fuel LOL.
Beside the guy I bought from carries a complete line of repair parts for RV refrigerators etc, many at substantial savings. He has got to make a buck too!
Thanks though for letting all the MacGyver's out there know that alternatives are available.

Just to be clear, what you purchased from Staples was most likely a CASE fan (probably square, black and an inch or more thick). Those things all over eBay are literally HARD DRIVE coolers/fan assemblies. Some with a switch added to them (mcguyvered for you), others just as you would get them to install on a hard drive. Those little notches on the side are there where the screws go to install on a hard drive. I put a couple links to them in my original post.

Just my two cents.

When I installed mine last year, I kept blowing fuse on circuit board.. Had it wired to the inside fridge light. Had to hard wire to a 12 volt source behind fridge. Just a little info, your results maybe different.

[asparky]

Makato.. I stand corrected, I thought they WERE case fans... The condenser fans probably are, and I probably could have saved more... But, I would have had to MacGyver and my wife is tired of me doing so LOL.

My next MacGyver is trying to come up with something to fill my airbags without a lot of trouble.. Quick, easy, cheap. LOL without having to get one of the automatic systems that the parts fail 3 days after the warranty is over...

Quick question...I have mine wired to a hot lead on back of dometic not the interior light. The clips are used to ground it so black wire is not hooked up. I went into the fridge today and accidentally bumped the fan in to the cooling fins. It then blows one of my 12v fuses. This has happened twice. What gives if the clips are the ground why would it short? Replace fuses and it works fine.

[Evereddie]

So as I understand the cooling fins are your ground using the clips that clip the fan onto the fins. Was the fan running at the time? Did it slow down or stop when it was bumped into the cooling fins?

[sugarjohnson]

Correct the clips ground it. The fan was running and I put something in the fridge which pushed the fan closer to the fins. Spark and it blew a 15w fuse on main panel.

[Evereddie]

There has to be an exposed positive wire on the back of the fan. If you look carefully you should see a dark spot on the fins where it sparked from. Or look at the fan. Put some electrical tape over it or use some liquid electrical tape and seal that place on the fan where positive is exposed.

[sugarjohnson]

10-4 I'll look for that.

[jacknife]

If you can't get a 12 v source inside run the wire out the drain hose and you can tap into the red 12 v and ground in rear. Used a solid dog run wire to thread it dowb with.

[M&K Hoffman]

I bought the fan set-up with the switch and since I found the alligator clip mounting a wee bit cheesy, I mounted mine by drilling a couple holes and used electrical ties to attach it to the rack. I also replace the alligator clip with a black wire, then fished both wires out the drain hose hole and attached the wires to the 12 VDC terminal strip. Work well.

This fan has three power options and will allow you to circulate from the bottom up as some of the “experts” recommend, which makes sense if your stuff is freezing at the bottom and too warm at the top. Either way an inexpensive way to evaluate with two no wiring options (batteries or USB to a power bank/jolt charger) and includes the adapter to run wire later.
