Refrigerator quit working

Five days into our three month road trip our Dometic refrigerator started beeping indicating that the propane flame would not light. We were driving down the interstate at the time. The propane tank was 1/4 full and I have now filled it up.  That’s not the problem. I can hear the igniter clicking. I opened the hatch to see if the spark was occurring somewhere where it shouldn’t. I had that before on a different RV.  That wasn’t it either. Not sure what to do now. Any ideas?

Check the control board for a 12 volt fuse. Make sure it is good.

What if you apply 12 volts straight to the valve. Does it open then?

Now, days later, the fridge continues to run on electricity only. I put a meter on the wires going to the gas valve. It’s a digital meter and it was jumping all over with values from 2 to 12 volts. Then it seemed to settle on 12 volts. The valve didn’t open.

Tonight we’re plugged in to shore power so the fridge is working.  When we get to Edinburg, VA I’ll check the voltage at the gas valve. I figure either it’s not getting power or the valve is bad.

Along the thought of the propane valve, does the stovetop light and burn?

Yes. Stovetop, oven, water heater all work.

Lots of easy things to check. Often it can take quite a while for the LP to make it's way through the line. Anytime I attempt to fire anything on LP I light the stove first to ensure I have good flow. Second, is to check if the LP valve is open. They usually close it when filling it. Your Fridge could have something in the ignition chamber like a spiderweb etc. Also could be an issue with the thermocouple. Will it light if you stick an electric match in there?

is the valve on your propane tank open?

Yes. All other appliances work. It was working fine and then started beeping while we were driving on the interstate.

I fired up the generator and it’s running on electricity just fine.
