Angry Pilot keeps going out

No name on oven
about 15 years old

Its a gas 4 burner stove with a gas oven, standing pilot.

Problem is, every time i close the oven door the oven pilot keeps going out.
I've cleaned and adjusted the pilot and it has a decent pilot flame.
i've even took off the pilot assembly and cleaned the gas orifice.
the oven goes on fine when the pilot stays lit.
it's just the pilot keeps going out when i close the door to fast.
i'm thinking some kind of vacuum, but all vents are clear.
the pilot tube is clear also.

Hello: acjammer

Look for a manufacturers rating plate located some where on the appliance. The manufacturers name and specifications will be on it. Use the reply button to post all that info. Not likely to be a 15 year old appliance with a constant (standing) burning pilot flame but it may have one. (???)

I too doubt there is air flow problem if the main burner remains on during the baking cycle. Why a pilot would go out when door is closed is a mystery. Pilot flame not likely extinguished from air flow as a result of simply closing the oven door since pilot is in the rear pf the ovens compartment.

As of this times I do not have a possible caused based solely upon info provided. If possible post a picture or two on a photo site then provide a link(s) to it.

Is this a very old range that has a thermocouple in the oven pilot, and a button you push to get gas to flow when you re light the pilot?

Or is it a mercury safety system that has a small pilot the gets larger when the thermostat calls for heat to engulf a small tube of mercury?

it's a thermocouple.
What happens is the TC(Thermocouple) is just below the standing pilot, small flame, but when the oven calls for heat the pilot flame gets much larger then hits the TC below which in turn starts the gas in the main tube(oven flame).

the Pilot only blows out when the pilot is in its low cycle(not calling for heat) and i close the door to fast, i've looked under thru the bottom front panel which is removable, while closing the door and some kind of air is sweeping over the pilot as i close the door.

I think what you are describing is a mercury safety system.

This system has a pilot light that has two sizes.

When the oven thermostat is not calling for heat, you have a small pilot flame.

When the thermostat calls for heat, the pilot light gets larger and engulfs a small tube containing mercury. When the mercury vaporizes, pressure increases in a thin capillary tube going to the oven gas valve, which turns on the main burner gas, which lights off the pilot light.
