Any absorption fridges that do not require 12 volts to run?

I like the 12 volt control board in our RV's Norcold 120V/propane two-way absorption refrigerator ... as I suspect that it makes possible use of it's 5-position temperature control switch to modify it's ON/OFF cycling times to help maintain proper in-box temperatures during extremes of outside temperature. ;)

P.S. I do carry a spare control board along however, right along with a spare igniter.

The Norcold N305/N306 refrigerars will operate on either 120 volt AC or propane. On propane, they do not need any outside electrical power, either 120 volt or 12 volt. Temperature is controlled by the size of the flame on propane instead of a thermostat. Not difficult at all with the aid of a thermometer.

Call me old, but furnaces in millions of houses have worked for decades without needing computer control boards or electronic thermostats. The good old fashioned pilot light and thermocouple has kept gas appliances from going up in fireballs for a long time. My water heater and furnace do not have any control boards either.

Having worked at IoT companies, and done IT for 25 years, I trust a mechanical device far more than an electronic controller, especially with the slipshod way most stuff is programmed these days ("It builds, ship it!) If an electronic gas controller messes up and blows up my rig, I get told that I agreed to the software's EULA by using it, so can't sue them. A mechanical controller likely has seen years, if not decades of testing, so it won't be absolute garbage.

Take my current rig's thermostat for example. It is electronic. If the temperature in the rig is over 100 degrees, it will not turn on the A/C compressor. I have to use an ice pack to get it to 99 degrees so it will turn that on. A mechanical, bimetallic spring thermostat would never have this problem.

What I'm looking for is as simple a LP gas fridge as possible, where the only electricity is used for the light, or perhaps a 110 volt subsystem when on shore power. This likely will be used for a class "B" van build. This way, I can shut off the battery while gone, and know my stuff will continue to be cold.

Except for the really small gas appliances where the small flame (or pilot light) burns all the time.....YES, all propane appliances have at least a solenoid to turn the gas on and off, which often is operated by a small electronic board which also takes power to operate.

P.S. If that was a rhetorical question, the intent doesn't always come across in a plain text message.

Who used the term, "blow up" to scare people? You.

Always funny when people use terms like, "blow up in the middle of the night", or such to get attention. The OP asked about refrigerators that do not need a 12 volt power supply and you come up with the scare talk. Nice helpful contribution.

A computer board is not absolutely necessary to keep one safe at night. Look it up.

So if you don't mind owning a fridge that can not shut off the propane when it senses a no flame condition or a high flame condition, then I bet with enough internet searching you'll find something out there with only an old school thermocouple.

Once again it depends on the age/quality of your RV water heater. But yes they have computer boards to control things. Maybe you know it by the name of a circuit board.

My last two water heaters had pilot lights and had to be lit with a open flame. They have NEVER blown me up in the middle of the night. And I don't think they ever will. One was made in 2016 the other in 2017 by companies that are still in business. Nothing scary about pilot light technology whether in a refrigerator, water heater, or furnace. Check out the water heater at home.

So what make and model of water heater do you have? Must be an old school thermocouple that runs the gas valve. Never said it was scary, you said that. I'm guessing you're drunk and just want to argue because you're lonely.

There are RV refrigerators that do not "Require" 12 volts to operate. Do a search of Norcold models. Jayco uses them on some of their smaller trailers. I have had two. They work okay, They do not have sophisticated thermostats except when operating on 120 volts. The rest of the time, the owner regulates the size of the propane flame to obtain desired temps. Not difficult at all.
