Oven burner won't light

[garn brown]

i've never worked on propane appliances before. I am a auto mechanic for 30 plus years, so i do know my way around a wrench. I need help on the Atwood-Wedgewood model2136 oven. The pilot lights fine, and increases the flame to light the bar, yet the bar wont ignite. I'm thinking bad regulator? Any info you guys can give would be very appreciated. Thank you.

I doubt if it's the regulator if the pilot light is mostly blue with a bit of yellow. On a home gas appliance, you usually have to hold in the gas valve and light the pilot light, then hold the valve in for a minute or so until the pilot stays lit then turn up the valve. On an RV oven, the pilot light is turned on by a valve and isn't controlled by the thermocouple in many cases. The pilot must heat up the thermocouple. The thermocouple senses heat and sends a weak signal to allow the gas valve to open. If the pilot flame is O.K., and stays lit, make sure it's heating the thermocouple, a small copper cylinder that should be touched by the pilot flame. Thermocouples go bad and doesn't send the signal to the gas valve. Use a small wrench to remove it from where it attaches to the gas valve and take it to a hardware store. They should be able to match you up with a new one.

Here's how to replace one in a water heater, (same idea as oven thermocouple)

Here's a video on how to test the thermocouple with a multimeter:

I'm sure its hard to see all the way back in there but I would check the alignment of the flame on that thermocouple.

Just had this very problem on my Wedgewood oven last year.
After chasing recommendations from appliance experts and replacing the pressure valve - which didn't solve it - I adjusted the location of the thermocouple to better align with the pilot flame - and it problem solved.
For some reason, the mounting bracket for the thermocouple was not close enough to sense the pilot. Found this by holding a lighter directly under the thermocouple when turning the oven on.

If the pilot didn't hit the thermocouple then the pilot will go out. The OP said the pilot is fine and the flame increases but the burner won't light. Lift up the stove top and see if there is a ball valve for the oven burner that is turned off.

Good luck with that!

Ok you have two possible options here, I will run through the lighting sequence and mark the suspects

First: The regulator, You turn to PILOT and push (usually) to override the safety valve so you can light the piot.. light it (mine fails here but read on) and hold the button in for a full mintue to let the pilot heat the thermocouple

Thermocouple then sends around 480 mV to the controller, this powers a magnet which holds the safety valve open

You relase the button, if pilot holds turn to "TEMP Desiered" (or in my case about 50 degrees above, long story) main burner should now light.

In your case, Pilot lights and holds so we know the safety and thermocouple is working and the pilot is working.

Main burner fails to light

Suspect #2: Controller not sending gas to gas jet (orifice)
Suspect #1: Insect has nested in gas tube and nest is blocking orifice.

I'll leave it up to you to figure out how to clean (easy, same as a torch).

On my oven, I have to turn knob up to broil. The oven lights then I turn it down to desired temp. No where in the instructions does it say to do this, but that is what it takes.
