Having lived off the grid for nearly 20 years I've had the pleasure to learn all the quirks of propane refrigerators. I had a range of gas refrigerators from a 50 year old Servell to a unit made in Monterry Mexico to a modified White Westinghouse residential with a purported Amish cooling unit and a few in between.
The WTH comes from my 12xx Norcold making me believe it was time to change out the cooling unit. Several months ago the ole box didn't want to get cold. It stayed around 50 degrees inside the lower unit, regardless of on gas or electricity or the ambient temperature. I emptied it, shut it down and opened the doors.
I found a place close by in Arkansas that builds and rebuilds cooling units and can build me a new 12xx unit for less than 700 hundred bucks and I can pick it up. Touted as the best unit out there so of course I was pumped.
Last week I needed some R&R time on the beaches of Mexico so I just went away. I came back and decided just for the hell of it to fire up the Norcold. To my happiness the thing bounces from 29 to 31 degrees in the lower portion on the number 5 setting. Ambient temps have been ranging here since I've returned but the unit has maintained as it should.
I've heard all the options of getting one working again, including turning them up side down to burp them. That won't be me trying to flip a four door because that trick rarely worked. I'm thinking the unit may have vapor locked if that is possible. What with the hydrogen and water and ammonia being heated and circulated constantly for over a year it could be possible for a fart to build up in the circuitry, who knows. I'm just glad I don't have to buy a battery to get the scooter out of the garage and remove the chock and pull the refrigerator and take it apart. For now that is! I wouldn't mind a side trip to Arkansas though
