A lot of people don't have the option I do.  But, with the trailer right here in my yard, I simply plug in the trailer power, and keep the fridge going on 120V.  Never had a problem, even if it is a  1976 model.  It seems (from what I've read) the basic problem is "downtime" for the fridges.  If they aren't running a lot, they tend to have problems.  I could be wrong, but I'm just basing that one various threads I've read.

You are right, Ed.  Keeping your fridge plugged in is the best thing you can do for it for longevity. 

There are 2 enemies of RV fridges...sitting around, allowing them to clog up over time, and rust eventually eating up your coils causing the gas to leak out and killing the fridge.

By keeping it always plugged in or running off propane, not only will it never clog up, the heated coils are much less susceptible to rusting out.  Since there aren't any real moving parts on these fridges, they won't wear out...and even if you do get electrical wear resulting in bad circuit boards or switches, those parts are WAY cheaper to fix or replace than replacing the cooling coils...or even the whole fridge.

The one thing they don't include in that ingredient list is the salts that are also in the solution, which is what causes blockages, and the rust inhibitor that keeps the water from rusting out the steel pipes. 

Fridges, especially older units, will last a long time so long as they are run level and run to keep that rust inhibitor flowing through the pipes.

Heat tape is most known for its use with mobile homes.  Since the plumbing runs under the floor and is exposed to cold weather, the "tape" is basically wires, encased in a strip, which warm-up and is wound around plumbing pipes and plugged into the house electric, thus preventing the pipes from freezing.  Note that, for many years, most mobile home fires were the result of heat tape because it wasn't checked on a regular, frequent basis for signs of damage from rodents and any areas where the casing may be wearing through.

I just bought  what I think to be in good shape, 1972 Indian, but I don't know anything about her history, the PO said that the Norcold refrigerator was a newer model.  I went to start it up, it seems to be running but never got cold.
PO said she had been in storage for a long time. I don't know anything about Rving, so everything has a learning curve. To burp this unit, after I figure out how it going to come out, is there anything I have to unplug, disconnect or remove first?
Thanks, everyone for your help, after this it's the furnace, water heater, air conditioning, etc, etc.

Nothing to unplug once you have it out.
Turn it upside down and leave it for a few hours.   If it isn't bad, you should hear the ammonia trickling pretty quickly.  If it is, you may have to do this 2 or 3 times.

My 74 Brave had a similar problem. We burped it, but that did not work, so we had an expert recharge the unit and refurbish it. It is a Dometic 4 cubic footer. However, it still did not get really cold. One of the owners of Sand's RV in Madison, Ohio suggested that we change the gas regulator at the propane tanks. He said old ones lose the ability to push the gas through enough to get the frig cold. After following his advise our frig runs like a new one.

Yep. That can certainly be a problem as well.
