Hello!

Finally rolling to Baja after years of dreaming.

Left BC Canada a few days ago.

By Sacremento all my food was spoiled !

Tried thermistor position with no luck.

Resolved to using the fridge as a cooler with bags of ice .

Then this morning I open the freezer and cold smoke is rolling out

Noticed the boiler has always been hot throughout the trip but the rest of the cooling unit pipes are now hot , so clearly the ammonia is completing the route through the unit now that it’s cooling.

Do I need a new thermistor? I’m gonna test the ohms today

Maybe it’s the control board or bad wiring connections.

Any ideas?

It’s 14 years old.

I could just buy a new one ($2000) and proceed on the dream trip worry free.

What would you do?

Gret a new one assuming you can find one and can get it installed (or install it yourself).

Its two years ago I also got the chance to use the frig as an ice chest. Not fun although it does hold the ice somewhat.

Although mine is a Norcold that was 13 years at that time. I did alot of looking at the options I had. I do not boondock always plugged in so need for propane was not neccessary.

I did not want to go the residential route as my carpentry skills were not goo enought plus it was hard to find a unit that would fit.

Getting a new norcold would require removing the front windshield
(thats what I was told) I most definitely did not want to do that.

So I looked at replacing the whole cooling unit. Save time and money all the way around. I ended up getting a totlly 120v cooling unit from JC Refrigeration
https://jc-refrigeration.com/
Very easy to replace new with old, great customer service all the good stuff. Can not be happier with the cooling capability of the unit. To me was a great choice.

If you do not fix your frig. I will not make for a happy trip. Mine boke down halfway into our month long trip. Many bags of ice.

Good Luck

replacement cooling unit would be cheaper then new can get replacement in 120volt/propane combo, 12volt compressor, or 120volt compressor. Not that hard to change the cooling unit I've done 3 so far by myself.

Are both the vents in the side wall? I had one of those little 6 cf fridges and it was the pits even though it was checked several times and I was told thatwas all it could do. You could try a fan in the back but it might be shot if it cooled before and this is a new problem. Craig
