My situation as we are in the process of fixing my 7 year-old Norcold which stopped cooling altogether. 120v electric and gas systems are both running to the fridge fine, but it won't cool down on either one.
The problem IS the cooling unit --- found little tiny yellow colored granule-type bits in the bottom of the outside compartment. That means ammonia is leaking out somewhere on the back of the fridge.
This problem is fixable, but the cooling unit replacement part (basically the internal guts of the frig) is right at $1600! Coming from Indiana, wonder it that means it's 'Amish' and will last a long time.
Considered dumping the RV fridge for a residential, but removing the RV one (windshield has to come out!!!), changing the setups for it, then installing a residential unit and trimming it out will actually cost more than fixing this one. The other good part of it is that maybe my ice-maker will finally be working again!
After researching here, I think I'm making the right choice for me.
>>> DOUG: This is a good time to install cooling fans? Could you post something about how we would do that, and where to place them for the best effect? And THANKS for all you do here, I'm learning a lot.
