Kitchen Gas Appliances - roper gas stove oven wouldnt light

i was working on an old oven and i thought it was a bad valve.
the pilot light got bigger when it turned the oven on.
i adj. the sensor still the valve wouldnt open.
so i took the valve out and put a lighter on the sensor and blew in the input and after 15s the valve opened.
so i blew out the pilot light a little and the valve opened.
but i took the orifice off the valve to check it and forgot how many turns it was.
i think i got it 1/2 out and the flames in the middle of the guard.
is this a good place for it.
could the valve be going out or to you think the pilot light just needed cleaning?

model# 1303a0e?
nat gas.

I would make sure you give the pilot a good cleaning and make sure the capillary bulb is in the pilot.

ya if it does it again i can take the pilot light apart and clean it better.
i just wanted to know if the orifice was set right.

Hello movieguy. Welcome to the Gas Appliances topic.

A cleaned pilot assembly produces the best pilot flame. A flame that has no yellow color in it and is all blue and very hot. Clear all openings and holes. Clean orifice inside pilot assembly.

Clarification:
Orifice is the small brass or bronze thimble like cup on the end of the aluminum gas supply tube or inside pilot assembly.

The hottest part of any flame, is the top one third (1/3) down from the tip of the pilots flame and the very outer edges of the flame. Those are the areas that are exposed to the most oxygen (air).

Which means the sensor must be encircled with the tip of the pilot flame and the flame must be all blue. That will produce the most heat to heat the sensor to it's maximum temperature.

Once you've obtained the above to the sensor, the burner will/should light quickly. About 15-30 seconds after the actuation flame (larger flame) contacts the safety element (sensor).

Hope the above helps to explain the conditions for best performance and provides the means to obtaining it....:thumbup:

Cautionary Reminder Note:
Before attempting any repairs, be sure to unplug the appliance from the wall receptacle power source first.

for the 3x time i need to know the setting for the gas valve orifice.

Sir

We are trying to help you, so kindly remain calm and be polite. Thanks!

This entire thread is in regards to and a discussion about a pilot flame heating a safety element (sensor). The advice we both offer you is based upon that information you provided.

A pilot flame heating a safety element. In that regards, pilot flame orifices are not adjustable. They are simply caps (thimble like caps) with a pre sized and drilled hole in them. They are not adjustable.

However, if you are referring to a burner flames size, there orifices are usually adjustable. The adjustment regulates the size of the flames in relationship to the flame spreader plate which sets on top of the burner.

Kindly advise which flame and which burner you're referring to. Pilot flame (non adjustable) or burner flame? (Adjustable) Thanks.

The sticky note explains how to adjust an oven burners flame and the size the flame needs to be in relationship to the flame spreader. Read it for additional information and adjustment instructions.

i need to know the setting for the gas valve orifice.
there is only one orifice on the gas valve.
what am i not explaining right?

?????????????????????????

wow what a waste of time.

Well there is no "setting" for a burner orifice or gas valve orifice as you call it. You have to light the oven and from experience leave it where you think it should be and then clock the gas meter to see it it is indeed at input or which way it needs to be adjusted. It probably will take a couple of clock test to get it to input. Why don't you call your gas co and have them dial it in? The original problem sounded like a dirty pilot orifice. In the future that can be tested in place by holding a couple of matches under the cap tube to see if the additional heat will open the gas valve.

Hopefully you won't find my effort to help you a waste of time.

wow finally a straight answer.
thats all i wanted to know.
yes thats how i tested the valve.
i just dialed it in by sight.
thats how i figured it was the pilot light.
i explained all this in the first question.
and ppl kept telling me about the pilot light.
i was asking about the orifice on the safety valve.
there used to be a rule of thumb for setting the orifice.
like bottom it out then unscrew 1.5 turns.
i took it off to check for cobwebs.

thanks for your help.
