The power is the white wire, not the brown wire (I used the brown at first and had to take it off and reattach to white wire) it is a little tight, there is some play by pulling the cable thru the hole with needle nose, about another i inch. You do not need all the wire on the unit, they provide enough for the power in the rear of the unit, if need be.
I marked the back of the freezer while it was out, cleaned with alcohol and attached the unit. It fits perfect. Attached the ground and done. Maybe 20 minutes.

got it running now to cool down and then will turn on the fans to see the effect on temperature.

If anyone is attending the rally here in Pennsylvania in September, I'll be glad to assist in the install for those who maybe timid about these things.

The Fridge Fix was originally designed to reduce the need for defrosting. Even a good working fridge can benefit from that.

I'd be interested to know if these fans help in the cooling process when the rig is parked with the sun on the refrigerator's access panels as well as they do when the sun is not on the access panels (in the shade). Can you do a test on both side of your trailer?
Is the sun on the access panels now? Please...Let me put this crazy notion about shading the panels to rest.

No sun, cloudy, very humid, around 75% and 82 degrees.

I suspect that there are three primary benefits from this fan system;

1. First, the fans continually introduce "new" air to the cooling fins and mix the air in the refrigerator. Therefore the refrigerator cooling system is responding to the average air temperature in the box, not just the air normally trapped in the vicinity of the fins. This I suspect will speed cooling.
2. When the refrigerator is loaded it becomes full of obstructions that block the very slow movement of air inside. Over time with the door opened and closed and new items being introduced it may become very cold around the fins and warm near the door and other areas. Those fans will force the air to circulate all the time, hopefully eliminating "dead air zones". I suspect that this benefit really helps when the refrigerator is loaded.
3. The fans of course keep the fins from freezing over. I think this is a "nice-to-have" benefit but the first two benefits mentioned above are more important.

It will be interesting to see your actual test results. I plan on camping for two weeks starting next Monday and will report back my actual (in the wild) results from the 2 fan system I installed last week.

BTW, I have the two digital sensors for the refrigerator and freezer with the larger digital display unit and always place my sensors on front of the wire racks close to the door. This placement always gives me the worse case inside temperatures readings.

...just my thoughts!...

I place my refer sensor on the door shelf and the freezer sensor lays on freezer bottom any may move with motion. The suction cups do not hold.

Hi Jim,
Does the original refrigerator light still work after you install the Fridge Fix fan assemble? Also if you decide not to run the fans will the lights on the fan assembly still turn on and off as the door is open and closed ?
Mark

Yes the original blue light operates with the door while the unit's fans and light is controlled by a switch, independent of the door.
I just checked, after 3.5 hours, the freezer is 16, the refer is 56, operating off 120v, outside is cloudy, 80 degrees, 71% humidity. Note there is a 5 degree differential between door and rear of refer temperature readings.
