Oven won't light but pilot will.

I have a 1985 Rockwood class C with an oven that looks like it may have never been used. It's likely, considering it only had 47k miles on it when I bought it, and the interior of the coach shows little wear.

The instruction manual for the oven/range says to light the burner (right rear) and let it burn for 2 minutes, then light the pilot in the oven. I did that. It doesn't say to let the pilot stay lit for a while before turning the knob to a certain temperature, but I've tried both ways. The tube never catches flame. It also doesn't say to leave right rear burner turned on after oven pilot is lit. I turn it off.

I have a feeling something needs a minor adjustment but right now, I have my left arm in a splint. Just had a wrist fracture operated on. No, this oven thing isn't urgent, but I'd like to use the oven if I can.

Thanks for any info coming my way. :)

    There are (quite a few) differences in the details of how these ovens work. My understanding is:

    The Pilot is controlled by the Oven Thermostat (where the Temperature Knob is)

    The Pilot does NOT have a "safety" on it (such as an expansion bulb) to shut the gas off if Pilot goes out

    Setting Oven Thermostat OFF of Pilot and ON to a Temperature (getting ready to bake) causes the Pilot Flame to Flare Up to a noticeably bigger (therefore hotter) flame

    This hotter Pilot Flame heats an Expansion Bulb in the Safety Valve (down inside the oven on the back wall) and the Safety is what turns the Gas on for the Oven Burner

    This means that either Valve (Oven Thermostat ***OR*** Safety Valve) could be bad if the Oven won't light, even if Pilot IS lit.

    Can you post Make/Model of the Range?

    In the meanwhile, look at the Pilot Flame when the Oven Thermostat is set to Pilot. See what it looks like. Then, select a baking temperature on the Thermostat Knob. Look again at the Pilot Flame. Let us know if it got bigger.

    If the pilot is lit, then turning the knob to desired temp should light the oven, it may take a minute or 2. I have no idea what the back burner has to do with it, unless it's just to ensure that air is out of the line.
  • Tank has lots of propane in it. If stove is getting gas, wouldn't oven also be getting gas?
