Now, the Pilot on the Ovens, you light it ONE time and it will stay ON during your Camping. You do NOT have to light it everytime you use the Oven. IF your pilot light goes OUT after a cooking run, then the Oven has a fault in the Gas system. Doug

I don't know how the oven would relight during baking if it didn't.

If you click on the picture it will take you to a video on Flicker.

If you are reasonably mechanically inclined you can do the same thing. As others have indicated it involves replacing the "click" igniter that lights your cooktop burners with a piezo igniter that has four wires(three for the cooktop and one for the oven.)

I just did a test on my Atwood oven.

Left pilot on, went outside and turned off gas. Pilot burned for a few minutes then extinguished. No gas smell. Turned gas back on. Immediate strong gas smell in the oven.

So, I guess that means the thermocouple doesn't work or never existed in the first place.

What Year Model RV? Yes, your thermocoupler is not working or you have a OLD Oven/range. Almost all Oven's you have to put the temp knob in the Pilot indent,PUSH the knob IN and light the pilot. Once the pilot is lit, hold the knob in(30 seconds) and release and the pilot should stay lit. Now, to your test. You shut the LP OFF, Then went out. You then turned the LP back on and smelled gas. A few minutes can be subjective. Maybe less than a minute? Once the Pilot goes out, it takes a few seconds for the Thermocoupler to cool down and shut on the Pilot tube of the Oven tstat. What I would do, is, do your test. Wait 5 minutes. Turn on the LP and then spray soapy water on the pilot burner and see if you have bubbles. Do not rely on your smell. If you are positive you have a LP smell and it is leaking after your test, you have a dangerous situation and you need to fix it. Doug

2002 coach, not sure of age of oven.I have to push the knob in to get it to move to pilot position, but no holding required.

Thermocouple did not have enough time to "cool down" with your test.

Needs a few minutes to cool down.

Thermocouples are basically self generating a small voltage when there is considerable amount of heat like a direct flame on the tip.

In essence you take two dissimilar metals and make a junction of those metals. When heat is applied to the junction a small amount of voltage is generated.. A thermocouple contains multiple junctions in series to get enough voltage to operate the gas valve.

[image]

That voltage is just enough to hold the pilot gas valve open on the oven control.

This is also often found in very old furnace systems and is called a "millivolt" system where the thermocouple was not only used for the pilot light but the thermostat circuit.

So, a thermocouple is housed in a metal probe, takes a few minutes to get enough heat into the junctions to keep the gas valve open, it also takes some time for the probe to cool down enough that it no longer generates enough voltage to hold the valve open.

Your experiment actually would be better if you simply wait a few minutes.. to allow the thermocouple to cool. Turning it off then back on immediately after flame has extinguished is not a valid test.

However, keeping in mind that while the gas pressure will drop to a point that there is not enough to sustain the pilot.. The thermocouple will hold the gas valve open a short time after no more flame and allow whatever small amount of propane left in the line still flowing. This will not be enough propane to be a hazard but you will still be able to smell it for a short time.

Furrion has an oven with an igniter. Anyone here have one? Pretty fancy. Needs to be hooked up to your 12v system. I don't know the price. Here.

You are so right.. no smell after waiting. Thanks! Strange.. that brings up other questions but I don't want to hijack any more.

I just assumed the reason for no igniter in the oven is due to how hot it gets in the oven. Unlike a BBQ where the ignitor is under the unit and out in the open air, the oven is enclosed and the burner is right there. The underneath section of the oven gets hotter than the cooking compartment of the oven. How much heat can an ignitor take before it burns up?

Same for your stove and your hot water heater, the ignitor is not enclosed with the flame.

For you that have installed one yourself, has it lasted?

The trick to lighting an oven is to hold the lighter flame under the thermocoupler so it lets gas flow to the burner, not just the pilot light - then you are lighting the burner where a lot of gas is flowing out, but you also have to turn the oven to the Low setting. You can decide if this is safe for you or not as I am not interested in opinions of course. I do this all the time.
