Refrigerator runs on A/C but not LP

Is gas actually getting to the fridge?

At least some Dometic fridge burner assemblies have a manual gas shut-off valve at the gas solenoid assembly. It looks like a large set screw, not so much like an obvious valve, and turns a quarter-turn from on to off or vice-versa. (It may be behind a sheet metal shield around the burner area.) If this is closed, opening it will certainly not hurt the situation. This is hardly the only thing that can cause non-operation on gas, but it is an easy one to check and fix if needed.

Here's a random picture from the internet showing the assembly (with various covers removed); the shut-off valve is just underneath the orange rectangular solenoid gizmo. (It's the one with the slotted head on the left, not the inset hex key one on the right.)

Mine had the same symptom last fall. The burner orifice was plugged so I took it off and blasted it with carb cleaner and all was good.

Do other LP appliances (furnace, stove, oven) work OK? If the issue isn't the cutoff valve on the frig, has there been any recent work on the LP system such as replacing a regulator, etc? I recently replaced the auto-switch-over regulator and had to bleed the air from the LP lines before everything operated correctly. I did this by lighting all the burners on the stove for a while (it's the farthest LP appliance from the tanks and regulator). After a few re-lights, everything works fine, now.

You can smell it.

What commonly happens is that after a period of inactivity, there's air in the gas lines which can be flushed out by running your stove for a minute, then retrying the refer.

I will check that. It worked spring 2018 but on last trip refused to ignite.

Yes I am getting gas to other devises. oven, cook top and heater. just not to fridge.

x2. do the stove burners light? is the main LP supply on?

Also, the fridge still needs 12V DC to run when set for LP.
