After a sucessful install of an Amish cooling unit last year it's now time to install a fan internally.Ordered the fan from rvcooling units. It a real nice fan with two small pancake fans. Also has a switch that can be used to turn t off if need be.I'm wondering if I'll have to run a power line to the back of the fridge. I have a 4 pin plug behind the light. Two leads for the light, and two leats for the temp sensor that clips to the fins. Now, I tested the plug with a volt meter & see the 12VDC when BOTH door switches are closed. With the light off I see NO 12VDC at ANY of the pins. Has anybody been able to get 12VDC w/o running a wire to the rear of the fridge. Must be 12vdc at the door switch, ideas?Thanks

Ran mine down the drain tube & to the 12 volt on the back of the frig.

I ran mine out through the drain line also. You need to pull the little "plug vent" off of the outside end of the drain line. Run the power wire out through drain line, cut a little slit (1/2") up from the end of the drain line, slide the wire into the slit. This allows you to reinstall the "plug vent" at the end of the drain line to prevent bugs from crawling up the line.I don't see how a bug could get up the vent line, especially with the wire inside taking up part of the space, but since you have it, you might as well reinstall it.Bill

It has that drip tray on the backside of the fridge but once I noticed water across the back of the fridge compartment. That drip tray had overfilled and it was overflowing. Perhaps with this fan it would not be draining so much water.Their MUST be 12VDC behind those door switces eh?

My drain line ran down & underneath the trailer. If you are running the drain line outside of the vent, as indicated, why can't you still use the line for the 12 volt connection ? Run the 12 volt through a small hole in the drain tubing further up from the opening & silicone the area of exit.PS, My tubing had a splice in it just before it went down through the base of the frig area & underneath. I undid the splice, ran the wire out & then reconnected it. You could add a slice to yours & make it easier to get the wire through.

The door switches hook to the power board, which switches the light on and off- the switches don't power the light directly.

As I said before, I was very impressed with this $14.00 fan.

Just ran the positive (Red) down the grey tube. Did not need to run a 2nd wire because fan grounds to fins via the clamps that secure it. Very impressed with the quality/build of this guy!

I think you & I have the exact same fan, got mine on Ebay last Spring. It works great. :B

I must have an old fashion frige light. I got the 12 V juice for my fan from the switch.

It is a 10 model. :h

No 12VDC inside the fridge on the 4 door models Dave. I checked the schematics & no go. The two door switches are wired to the control board serially. No 12VDC.

Running the power thru the drain hose was an easy solution. So far so good. Great fridge tems & looking forward to those fins NOT iceing up!

Good call Chris, I was just looking over the schematic in the service manual & quickly relized that would NOT work.
