Fridge-Fix by Smart RV Products - has anyone installed?
Has anyone installed one of these - article in Trailer Life October 2014? Does it work and did it help with frost buildup. Thanks

I just removed mine from the old RV and tried to install it in the new one. It has a Norcold frig. For the life of me I can't get it to work with the door closed. I also can't find the instructions from when I bought it years ago. Would you refresh my memory about where the wire attaches to the light?
There were two different designs of the 1200, maybe Chris can tell you how to ID them without a volt meter.
On mine they brought +12 into the box to the light and switched the light with ground. I hooked the ground of the fan to the fins that are themselves grounded, and tied the + side of the fan to the LOW side of the lamp, so the fan actually draws current through the lamp. That's OK because it was running too fast anyway. The advantage to this is that anytime you open the door, the LOW side of the lamp, that same side the fan is tied to, goes to ground... Lamp lights, fan stops.. :). Confusing eh?
At some point in time all this changed and they started switching +12, so there was no place to power the fan. Short of drilling a hole, you can feed a small wire up the drip,tube from the rear of the fridge.
I ended up feeding a wire through the drain line. I found a wire that is only hot when the fridge is on. My new fridge switches the +12, not the ground like the old one. I appreciate the info though.
