Ovens generally have a couple of safety devices fitted meaning no gas gets to the oven unless there is sufficient gas pressure. There is also a valve controlled by a thermocouple. The valve prevents gas passing. There is a bypass operated by either a button or pressing in the oven control knob which allows gas to flow to the pilot light (and sometimes the burners). When the pilot light is lighted and has been burning for about half a minute with the flame correctly set to heat the thermocouple bulb the valve will switch on the gas supply and the knob or button can be released. The burners will initially be at maximum until the oven thermostat reduces the flow to maintain the temperature at a preset level.
If gas isn't reaching the oven and the pipework, oven control and thermostat is ok then the safety thermocouple is either defective or wrongly fitted.
