Marv and Cathy:

Remember, when you bypass the box (with the red light) you lose your overheating protection. My experience has been that a variety of conditions will trip the box....not necessarily conditions that come from a faulty frig....like excessive moisture (during a rainstorm, etc.).

I suggest you purchase a magnet capable of holding 25lbs (about 5 bucks at most hardware stores) and use it to reset your black box by passing it over the box. It may take a few passes; you may have to vary the conditions (like power on or power off) and it will eventially reset. Then at least you have protection until the next ghost appears.

Important: With each reset, carefully check you unit for leaks (yellow stains), failed fans, etc.

Hoe this helps....Stan.

I intend to replace my 1200 with an Amish built replacement cooling unit from RV Cooling Unit Warehouse. They also provide great instructions and a variety of videos to help you do the switch out yourself.

My experience with replacement cooling units has been less than good. We have done a number in our shop with less that perfect results. We usually wind up replacing the whole refrigerator.

If you have a red led light on the over temp. box just reset it with a magnet.

 

Use a fairly strong magnet placed on the led light and hold it there until you see the light go out.

We have  Norcold 121X Series fridge so I don't know if it is a 1200 but we have had a recall on it and we took the coach in for that.

 

We have gone full time since Dec 27, 2012 and the fridge keeps frosting up...we just defrosted it a couple of weeks ago and it is frosting up again.

 

Any sugggestions???

 

Also how do you find out if you can put in a regular fridge in your coach...we have a Tiffin Phaeton '07??? 

Thanks, Pat

Pat,

 

Frost is a normal part of a NON frost-free refrigerator. 

 

Causes of excessive frost buildup:

High humidity

Lots of opening/closing refrigerator

Poor door seal (use the "dollar bill" test all around the door-- there should be equal drag of the bill all around the door.  If looser in areas, adjust door).

Missing condensate drain restrictor (an open condensate drain hose will allow warm, humid outside air into the refrigerator).

 

Defrosting every couple of weeks is not abnormal, and is a good idea any time ice exceeds 1/4" thick, as thick ice on the refrigerator fins/freezer plates degrades cooling performance.
