NORCOLD N306 2-way trouble on LP not staying cold

[Coloradokev]

Thank you so much Kevin.
I can find only one thermostat on pdf. Link in previous reply) On Page 6 & 7. Item #6 - Thermostat # 636495, which an RV Parts company told me to buy. This t-stat seems to correspond with the electric side (see attached pic (and pdf) where this t-stat is second from left where the dash board shows the electric "plug" symbol,
Item #20 - thermocouple extension seems to be associated with the GAS side. Is this the gas "T-stat" you are referring to? OR where would the gas T-stat you are referring to be located?

There may be no thermostat on this unit. Notice the legend on the brow. It indicates variable flame settings. Low when turned counterclockwise, high when turned clockwise. This is the valve knob on the right of the brow.

There is not a thermocouple, that is a gas pressure tube you are looking at.

Ok, now I'm pretty confused. So your guidance is most appreciated!!!
You mentioned earlier- "So there are two thermostats. One for electric and one for LP. The thermostat has the small tube that goes into the ice box. According to the diagrams it's located on the top just behind the brow. The tubes gas actuates the needle valve via the diaphragm." AND "Your solenoid may have a blockage."

1. So there is NO LP thermostat (only electric)?
2. I should return the electric thermostat I bought?
3. What next - clean the burner orifice again?
4. solenoid - where is that located? Do I clean it or replace it?
5. any other suggestions?

Let's start over. I say that because of new evidence.

Parts lists like in the PDF can't offer clarity a picture can.

All put together paints a complete picture. So I, like everyone that responded, made assumptions that were wrong.

So!

First assumption was electronic control that is most common on the rig of it's age.

The PDF has picture drawings that lack detail that you provided with the picture.

The assumption based on the PDF was also not complete.

The thermostat was a correct call, it is a thermostat! However the picture of the brow indicates it is the electrical thermostat not gas. I assume there is no compression fitting for LP on it anywhere. If there is that information may change My mind again!

On the brow the legend shows for the knob on the right from left to right: low flame (lowest setting for gas) medium flame, high flame, and the symbol for electrical on/off.

That knob/valve is analog to your stove top valve. When the burner is on nothing else is working. On an absorption fridge that has proven itself, and it did that with the 115 system. That Valve is plugged, or is set by the user to low to keep the temperature.

Such a fridge relies on human attention. There is no thermostat for the LP function.

Orfice cleaning is not a regular mantainance procedure. If there is a problem with gas flow it is the far right valve, that has an obstruction (not very likely). Play with settings on that valve and see if it cools down.
