Does it actually have a "pilot" (which is a small gas flame)?
You can read about a number of different types of gas oven ignition systems at the following link. It describes common failures and what observations are needed to properly diagnose each.

If any parts are required, you're going to need the appliance's brand name and also its model number *as printed on the appliance's model and serial number tag*. You can find tips for locating that tag on your appliances in the 'Repair Parts' section of my site linked below.
BTW. We will also need that information here so we can find out how whatever model of oven you have was designed before we will be able to provide any specific replies to the additional observations you can gather about the problem symptoms.
Yes the wall oven actually has a pilot (small gas flame). I did look on the recommended website & found that it is a pilot ignition system.
The brand name is: Gaffers Sattler
The model #: A92-4lX.
The serial #: M 1982308 (the last digit is either an 8 or B - difficult to read)
I found a tag that had the following information on it (whether or not it is relevant, I wouldn't know): "On or after 8th July 1978 within the state of California this appliance is to be installed in mobile homes only."
** Yes the wall oven actually has a pilot (small gas flame). **
Than someone is going to have to check its functioning compared to how that system is suppose to operate as described at that link. Possible areas of troubles are with the operation of the pilot flame or the functioning of the gas valve and its thermocouple.
I also have a gas wall oven Gaffers & Sattler and live in a mobile home the pilot light is always lit and when I turn the oven on the gas valve that actually heats will not go on. I think I need that part only can you please help??
** when I turn the oven on the gas valve that actually heats will not go on. **
The oven safety valve in the oven (when operating) allows gas to flow to the oven burner which then lights and heats the oven... assuming the thermostat is allowing gas to flow to that safety valve.
** I think I need that part only **
Which, the oven safety valve?
** can you please help?? **
We would need the appliance's brand name plus exact model number in order to check to see if parts are available for it. If you post that information (and also the part you're looking for) we can try to check into it.
