(Pls note this is the oven, not the cooktop/stove)This has happened to me twice In the past week and it makes me concerned.Propane tanks are full. Light the pilot. Crank up the temp to 450. Burner lights off. Check it 10 minutes later by feeling outside of oven. Hot!15-20 minutes later, go to get food. Not fully cooked. Burner and pilot out. No gas smell. Relight and finish cooking.No failures on the cooktop or fridge (fridge is on propane 8-10 hours a day)First time the happened, outside temps were in the mid 30's. Second time, outside temps were in the 60's. When failures occured fridge was on 110V and cooktop and water heater were not in use.Added note: temperature control on oven has always been poor. I have learned to adjust cooking time a bit and always set the oven temp to 450.Oven is 10 years old (came with TC when I bought it used.) Can I expect this problem to get worse?

My first guess would be the propane itself. In many areas they sell butane or a butane propane mixture. The vapour the stove runs on is created by the gas boiling in the tank, the boiling point of propane is -44 F. So at a temperature warmer than -44 the propane in your tank is boiling. However butane boils at 30 to 34 F. I suspect what your experiencing is fuel starvation, basically you're burning gas faster than the tank can supply it so you run out of gas and the burners all go out, even the pilot light.

I would guess the pilot is a bit clogged, and the pilot flame is too small. Once it gets up to temp, the main burner goes out, and the pilot cannot keep itself lit.

Our gas oven has a somewhat similar "feature". When preheatingthe oven, we have learned that we must crack the door for the first 8-10 minutes of the preheat. Otherwise, it will go out.However, once it is up to temperature, it stays lit, unlike yourcase.This has been the operating condition of the oven since new in '05, and has not changed for better or worse.

I was have the same problem with my oven, since I got my rig. Has it always been like that? I adjusted the thermo-couple probe to get it nearer to the flame and center to it. It has been working great since then. Give it a try. Gary

Using a straw try blowing at the pilot hole with your lungs and see if it clears up. Also, a little bit of carbon might have built up on the end of the pilot tube. Scrape it off with something like a fingernail file. You might even try banging on it lightly with a pair of pliers. Be careful though you don't want to make it worse and plug the hole completely up. It's such a teiny tiny pilot hole and flame it doesn't take much to get it clogged. Then when the main burner goes off, which sometimes happens with a poof, it blows the pilot out.

I have found it is easier to light the oven off by lighting the pilot, setting a timer for 2 minutes, then setting the temperature. Cranking up the temperature before the 2 minutes, the pilot will usualy go out.

Bad control valve (Thermostat) it contains a safety device that senses the flame of the pilot.

You may have something here...the temperature control is horid. The way I have learned to use this oven is to always crank it up to 450, no matter what. I did put a thermometer in the oven one time and tracked the temperature and it swings +/- 150 degrees. Setting the temp at 450 it averages around 325.

(Every time I make Cheesecake) but I do use it from time to time, Last was 12/17,, Took the cheesecake to the Pot Luck on the 18th (Glad I decided to do that, things happened on the 18th and I was pressed for time, Unlike so many things you can make in advance, Cheesecake MUST be made in advance, so all I had to do was take it out of the fridge and go).

mmmmm.....cheesecake!

Doubtful, as twice I was baking up some biscuits, got things in the oven and did not open the oven until 24 minutes were up (the normal time that has worked in the past to get them golden brown) and they were only half baked and the pilot was out.

Loss of pressure

I usually heat mine well, then fire the main burner, then it holds till time to turn it off.. I do not use it often, (Every time I make Cheesecake) but I do use it from time to time, Last was 12/17,, Took the cheesecake to the Pot Luck on the 18th (Glad I decided to do that, things happened on the 18th and I was pressed for time, Unlike so many things you can make in advance, Cheesecake MUST be made in advance, so all I had to do was take it out of the fridge and go).

Worked well.

I've wondered how and if I should try to get any excess oil out of our MH tank.
It either 37 or 47 gallons. Be a bear to lossen connections and move around to drain through pressure hose.
Is there a fitting, on the bottom, of these tanks, to accomodate draining oil etc out?
Is there a low point on these round tanks?
Would it make the tank lose certification to have one installed?

Hmmmmmm? Oil in the propane lines is never a really good thing. That being said, I would proceed with some of the earlier suggestions with regard to cleaning the thermocouple and making sure that the pilot gas tube is free of debris. Can you get us a picture of the pilot light when lit - I'd like to see it's color and flame profile. Butane and some lower grades of propane have been known to contain small quantities of impurities or even "sludge". It would be wise to empty the bottles fairly often to keep stuff moving along in the lines. Empty one (A), change over to the other bottle (B), fill the empty one (A), empty the current one (B), change over to (A) and so on.

Cleaning the propane lines can be tricky, dangerous and not for the feint of heart or inexperienced. Keep us posted and good luck!

Cheers!

These two cover it pretty well, pilot is not strong enough to keep the thermocouple hot enough, OR the thermocouple is failing.

May have found the problem. I pulled both propane bottles and when I removed the second one, there was two teaspoons of what appeared to be a light oil that came out of the hose that connected to the second bottle. Note - I had not remove the second bottle for some time as I would run the first one down until it was empty and then I would refill it.

Could oil have been dumped into the second bottle some time when I had it refilled?

Absolutely!

Open the oven and use a small piece of sandpaper and lightly sand the thermocouple. This cleans the rust off. It's the little metal tube that is in the path of the pilot light. The pilot heats the thermocouple, which tells the gas valve to open and stay open. Make sure the thermocouple is in the path (middle) of the pilot.

The other thing that might be occurring is that as the oven temp cycles and the burner relights, it's blowing out the pilot. Make sure that any kind of shroud around the pilot is positioned properly.

Will try that this week.

I would start with what CT_WANDERER posted.
