Vulcan oven will not stay lit

Have an old commercial stove/oven/griddle combo, purchased second hand. everything works, but when I lit the oven pilot I was able light the oven, everything looked operational for a few minutes. After shutting the gas off I had to relight everything and again the pilot lit, then the oven. I set the oven for 400 and put an oven thermometer on the rack. The burner turned off and I am unable to get it to relight. Pilot is still on but looks very small. I can push the red button on the gas valve in and the pilot is normal momentarily. No joy on lighting the burner again.

any thoughts are appreciated in advance

Re: vulcan oven will not stay lit

I would take out the pilot and clean it up and see what happens,also look behind the unit and see if theres a gas regulator on the gas line,if so you will see a nut on it take it off with a pair of pliers and clean as well.that valve is actually the saftey valve,when the pilot lights the flame impinges on the thermocouple and that sends a millivolt back to that valve in order to open.if none of these resolve your problem i would replace the thermocouple first as this is a cheap part and easy to put on.if you need a part # i can give it to you.let me know.

Oven pilot will not stay lit

Strange to hear about a pilot-flame. Is it an old oven? Commercial unit? Look for a small valve at the end of the pilot gas-line and see if it is shut off. If it's on, okay. But, is gas getting there being blocked elsewhere? There may be a flame safety-switch, a sensor by the pilot, or some other thing that has a release button for lighting the pilot. You hold it in until the sensor heats up, and then it will stay lit. After that, there may be a re-set button to get gas to the main burner element. Basically, you have to trace lines back until you find the hindrance. CAUTION:With all gas appliances, you have severe danger of causing an explosion, and untimely death, or injury, so if you have any doubts, get a qualified guy on it! (It takes a while to grow a beard back, too.)

Don't know how to light the pilot light in the oven.It is a Garland ten burner two ovens. It is about 11 years old. Where is the pilot light and how do I light it.

Most commercial ovens have a manually lit pilot. There will be a button somewhere on the range that you will need to push in so gas will come out of the pilot assembly. While holding this button you will the light the pilot and will need to hold the button in for about a minute or two until the pilot stays on after you release the button. Look around the bottom panel,top panel or side panels(you may need to remove one) to find the button. they are usually red and may not look like a button. If you find the button and the pilot does not stay lit then the thermocouple might be bad. If you push the button and do not get any gas coming out of the pilot then there might be debris in the pilot assembly causing the gas not to come out. In that case you could try and tap the assembly or blow with compressed air to clear it. But in most cases you will need to remove the pilot assembly and use a really fine wire(like a metal tie-strap minus the coating) to clear the pilot orfice.

Oven keeps randomly shutting off. wont stay lit

pilot sensing device should have tip in the flame only, calibration of thermostat possible with butto removed, if standing pilot is going out possible thermocouple or pilot generator or gas valve bad! could also be a safety hi limit opening in control circuit if has one?

Propane not getting to oven... stove top works fine..

The pilot light must be lit and stay lit before you will have any propane coming into the oven. This is a safety feature.

Old Magic Chef Gas Oven won't light

sounding like thermostat isn't working. If you could ohm out the t-stat should be closed when you call for heat. If that passes the test then only thing it could be is the gas valve.

Pilot light

When you smell it all the time? If so, this is dangerous. If it only happens when you're trying to start the oven, no problem. Push the red button and hold it while lighting the pilot. Hold for 30 REAL seconds more. Release. The pilot should stay lit. If not, get a service tech.
