Stove burners refused to stay lit
Stove burners refused to stay lit. We have a 2016 Pendleton trailer. It has a stove top actually made in Italy. I believe it’s supplied by Atwood. The model number is CU434. It has three burners. I believe it’s used in a variety of other trailers. We are friends with a 30 foot trailer and they have the same stove top. From day one we’ve had trouble with the burners not staying on. Right rear one works reliably. The other two less so. We’ve been to the dealer where we bought the trailer without any success in resolving the problem. It sounds like a thermal couple problem to me. Although I’m hardly an expert in the subject.
Has anyone else had this problem? If so, how did you resolve it?

Does the water heater and or furnace work correctly on gas?
It yes, sorta rules out a gas system supply problem.
Doesn't a thermocouple tell a gas valve that the flame in an automatic firing appliance that a flame is present and ok to continue supplying gas?
And a stove burner has you controlling the on/off valve.
I am not familiar with your model stove.

If your other gas appliances are not working, check for a crushed gas line. usually under the curb side a frame rail, follow it along until it enters the coach then look in the coach for crimps or kinks in the line. It also could be a faulty regulator, tank pig tail, or tank switchover valve.
If the other gas appliances (Fridge, Hot water heater, furnace) are working properly, then check for a crushed or kinked gas line that is feeding the stove.
A crushed or kinked line will allow the pressure to build up in the line all the way to the burner control valve when the valve is closed. Once you open the control valve, the initial flow will be ok until the pressure bleeds down and then the flow of gas through the crushed part of the line will not be sufficient to sustain the flames.

One more thing to try
If your right rear burner works ok but the other two do not,when operated separately with no other burners on, then check for problems in the gas and air supply to the other burners. I have had problems in refrigerators due to spiders in the budner area that put tiny webs across the orifice and hot water heaters due to mud bugs nesting in mixing tube feeding the the burner.
Take the burners apart and inspect for tiny spiders or larger bugs. Inspect the orifices and make sure you can blow air through them. Do not stick anything in the orifices, you could damage them. Check the air mixing ports to make sure they are clear and air can mix with the gas.
If you do not feel comfortable working on your stove, then find a good RV appliance repair person. The manufacturer can suggest someone.
Not every RV dealer has technicians who can diagnose and repair every appliance.

It sounds to me like the gas regulator pressure is a tad low and the flame just leans out and dies. I say this because you mention it has always been a problem. Certanly as others have mentioned, it could also be an issue (kink or restriction) with the line that feeds the stove top.

on my gas stove top, i removed the top off and discovered spiders and dirt dawbers had made nests in the lines. I used air compressor and with short blasts blow out all 4 burners tubes and used toothbrush to clear the buggers.. works great.. i'm now working on the range controller since I'm not getting any gas to it. lines were in good shape except for the bugs.... I also found a snake skin behind the range... (no snake)

Thanks all. Propane tanks are full. We’ve been camping primitive for the past week. Propane water heater, frig and furnace worked fine. Just the problem with the stove burner. Pulled into a rest area for lunch and I was able to get all the burner working at the same time. I held the starting knob in and let them burn awhile. I continue to think it might be a thermocouple problem. Stopped for the night and got them all working again.

i am not aware of any stove with burner controls as sophisticated so as to have burner management. I could be wrong, but... I would continue to advise you adjust the regulator for a bit more pressure. They are adjustable.

Update
I took all three burners apart and cleaned the thermocouple probes with steel wool. All three working fine right now. Only time will tell if this fix stays.
