Great tip Matt….its tips like these that can save us owners alot of time and expense with simple remedies.

OK after talking to Norcold and a couple service techs, one thing that came up was the fact that with the 2 way refrigerators, the cabinet they are mounted in is faced with wider cabinet boards to take up the space that would normally be used by the electric only refrigerator. If you read the instruction manual for installation, it calls for less than 1/2″ of clearance and insulation from the front rearward 19″ around the cabinet.

Unfortunately KZ RV Neglected to insulate the cabinet space where the refrigerator went in, and as the burner got hotter, the outside of the refrigerator got hotter, making the inside warmer, and as the inside called for colder temps, the burner would get hotter and hotter, warming inside even more.

So I pulled the fridge Sunday, stapled in 18″ wide strips of R-11 on the top and sides of the cabinet, and reinstalled the refrigerator.

Before Insulating, on an 75 degree day, the intrerior on temp setting 9 would get down between 45 to 50 degrees (a 25 to 30 degree drop in temp)

After insulating, on temp setting 9 now gets down to 24 degrees with an outside temperature of 78 degrees ( a drop of 54 degrees in temp)

I figure problem solved, and cost me a couple hours of time, versus having the dealer do a warranty repair and hold my trailer for a couple weeks, along with taking 4 hours of driving back and forth just to get the warranty work done.

my fridge seems to be working really good..in fact last camping trip when I returned home, I emptied out the fridge and left the door  open about halfway with a towel inside to capture any condensation. After a couple hours I suddenly remembered I had left a bag of ice in the freezer, and thought I would find a puddle of water on the floor or wet towel…I ran into the trailer only to find inside the freezer compartment a solid bag of ice cubes !

Finally It's fixed, and not too soon!

Spoke to Norcold again about the cooling issue. They recommended I check the burner or take it to the dealer. I asked "how close to the right is the thermal sensor supposed to be?" They didn't know, but the tech told me that the left side of the fins is warmer, and the right side is cooler, and if it ice's up it's too cold for the sensor. So I asked if I moved the sensor to the left one fin, what would it hurt. The response was that he didn't know. So I tried it, reset the refrigerator to LP and temp to 5, with the sensor moved to the 5th fin from the right. 8 hours later the fridge sat at 32 degrees. 24 hours later and 3 bottles of water, and it was at 32 degrees. So I switched to electric. Lo and behold the temp climbed briefly to 40 for 1 hour, then dropped to 32 degrees without touching the temperature controls at all.

So add in that if the sensor is on a fin that get's covered in ice and the temp keeps climbing in the refrigerator, moving the sensor one fin may help also, along with moving it up and down.
