Oven pilot won't light
The stove is getting gas. The stove top works perfect.
The pilot light in the oven will not light.
If I keep the lighter
on the thermal coupler, it allows gas into the burner and the burner ignites (not the pilot). Eventually, the burner goes off (assume it reaches the set tempt). Once it goes out, there's no pilot to restart the burner and regulate the temp.
Can a pilot light go bad? Any ideas?

Yes the pilot can go bad. It's a capillary tube and the pilot heats the tube and it keeps the gas valve open so it can work on demand by the thermostat. They can go bad and if you can reach it they should be pretty universal and easy to replace. Look up appliance repair parts nearby and they should have it.

We had the same problem, we just turned the oven on to full used a long match and the burner lit...then we just turned the temp down to the correct temp. We had lit one of the stove top burners first to ensure gas was getting to the stove.

If the pilot won't light at all. There must be a blockage in the gas portion of the pilot.
If it lights and then goes out. Probably a bad thermocouple. Or a bad connection between the thermocouple and the gas valve.
Without a functioning pilot the burner will not stay lit. Since it turns off when it reaches temperature.

The pilot won't light at all. If I unhook the pilot gas line from the oven controller and push the pilot knob, I should smell gas. Correct?
If smell gas, I know there's a block.
If no gas is present, could it be the oven controller?

Sounds like a spider web at the burner orifice to me. Take the orifice out and clean it with a wooden match stick ONLY, never use anything metal as that could enlarge the orifice hole and give you a much larger pilot flame.

I disconnected the pilot light tube from the oven controller (see photo).
When I push the pilot light knob, there is NO gas present at the spot the tube connects to the oven controller. Should there be gas when the knob is pushed?
The tube seems blocked too. I tried blowing from the top. Is there a safety close-off between the top of the tube and the pilot?
Thanks?
Jason

Not sure..but isn't the disconnected line the main burner line? Is the pilot line the small one above it and the thin one the thermocouple?

Thermal coupler is copper line above. Thin line goes to a thermostat. Larger silver line on top goes the burner. Supply line is not VIsAble.

Got it. You have a different model than mine, but yes, I believe there should be flow when the knob is depressed.

I've attached 3 more photos to help show the setup. This is not an original stove.
Does anyone know if the pilot light supply tube is open all the way from the oven controller to flame?

Yes; you should smell gas with the button pushed. The purpose of the button is to over ride the safety circuit long enough for the pilot to light and heat up the thermocouple.

Ok. Since there is no gas, I'm assuming the oven controller is bad. I'll remove it and clean with a can of spray air. ..if doesn't work after my "cleaning", I'll order a new controller.
Thanks for all the help. I'll post the solution in a day or two (hopefully).

I disassembled and cleaned the oven controller/thermostat with canned air. The pilot light now works. Some debris or plumbing tape blocked the hole. Now the thermostat does not work.
No matter the temp on the knob, the burner is fully lit....always.
Any ideas?

Your first post suggested that the thermostat was working, because the burner went off when the oven reached the set temperature. Suggest you check everything you took apart when you blew the obstruction out of the pilot light. Something may have remained disconnected, or might have moved out of its correct location.
I know when I work on something, I often cause something while I'm trying to fix something else. I'm just clumsy, I guess.
Good luck.
