I've been experiencing an issue with my Norcold refrigerator for a while now and I can't quite figure out what I need to do to fix it, so, of course, I come to you.

I have a 2004 32T Journey. My refrigerator is in the slide. I have it set on the coldest setting (9) and during the summer the coldest it will get is 40 degrees, but during the heat of the day, it will get as warm as 55 degrees in there (which is obviously too warm). I've replaced the thermoster and run the diagnostic check and everything checked out. The fans are running, so its not that. I have the same problem whether I'm on electric or gas. The freezer works just fine.

A friend of mine believes that the issue may be a design issue - the fact that the refrigerators on slides are vented out the side of the coach as opposed to out the roof. He also has noted that some folks have added additional fans to help cool their refrigerators.

Before I take it to have it serviced at a dealer (there aren't any in my area that I have very much faith in), I thought I'd see if anyone here had experienced the same problem and what fix you might have made to correct it.

Thanks for all your help.

I have a slide mounted 4 door Norcold and typically it is set to 5. A higher setting results in freezing of veggies.

Reduce the setting to 3 or 4 and see if things improve.

All the RV refer "DIY sites" say the same thing about your problem. The refer needs heat, refrigerant and air movement across the coils to work. You have the heat and the refrigerant as evidenced by the 29* freezer temp. What you do not have is ENOUGH air movement across the coils. 2 things cn help: get the refer. side of the coach into the shade and/or add additional fan at the bottom of the coils. A marine bilge blower works ok for this task and is explosion proof.

The most probable solution is air flow. You need to make sure that there is proper venting to draw air past the coils especially in the heat of the summer. Here in Texas this is very typical problem we experience. I will include a site that offers assistance for all refrigerators and is excellent. Hope this helps.

mine vents from the top. rvmobile says to mount vent there. Has anyone done this and if so, how?

Obviously you have a problem of some sort.

When you said you ran diagnostics, did you download the service manual from Bryant RV and run the technician's diagnostics?

You could have a fan problem but I don't remember if the diagnostics can pick up a wonky fan or fan thermostat. If you remove the lower outside vent panel and stick your ear in the opening, you should hear the unmistakable whine/hum of the fans running.

Check your cooling unit on the fridge back - if you place your hand on the ammonia plumbing, it should feel hotter on the bottom section and gradually get a little cooler as you move your hand up the pipes.

I just checked my cooling plumbing with a non-contact thermometer and my reading are: (starting from the bottom pipe and going up)

- 156 degrees
- 140
- 120
- 114
- 112
- 110

John_Canfied Am I safe assuming that the fan/fans only run during the AC power mode when thermostatically called for? And thus when on LP the airflow is all accomplished convectively?

The fans (two) are operated by 12VDC and are thermostatically controlled. They operate when the condenser fin reaches 130 degrees and turn off at about 115 degrees. I'm pretty certain they operate in AC or propane mode.

As far as I know, the only difference between LP and AC modes are the heat source for the refrigeration absorption cycle. Lp is flame, AC is electrical heating elements.

My Norcold is doing about the same thing, refer running about 35 to 45 and freezer 10 to 30 degrees. When we got home I shut it off and checked the vent pipe on the top of the burner, it has a cover on it and was pushed down so I hope this was my problem. The refer is in a slide. The metal plates are not really attached to the coach or refer and will move around. Soon as I clean the refigerator, I will see if that helped.

Bonnie, installation is most likely your problem. THe unit will only perform well when it is installed as per the manufacturer's specifications. Additional fans may be needed for a side discharge vent design for very hot and sunny conditions. If you do not have the installation instructions, they can be downloaded. CHeck to be sure the max and min clearances are present in your coach; if not then that is where to start.

Our Norcold N84x is mounted in the Kitchen slide-out. The stack fan runs as John Canfield states. Check everything in the stack to insure it exactly meets the Norcold Installation manual specifications for your model unit.

WE have had the exact same problem in our 2008 Tour with the Norcold 4 door fridge. Winnebago checked it out and found everything to be right, but temps would still climb to the high 40's even in cool weather.

I finally noticed the sensor in the fridge (upper right side of the refer section on the fins) seemed to be iced up. I defrosted it with my hand until all ice was off it and things worked great -- back down to 33 degrees. Any idea why this worked?
