Thanks for counting on us to help with your appliance problem. My name is ***** ***** I look forward to helping you! It sounds like the orifice hood may have been tightener a bit too much. When it lights, is the flame about 1.5-2" long? Can you post a picture of the flame at the broiler burner?
Customer: replied 2 years ago.
No flame at the broiler burner. Only at the orifice. If I close the oven door and then open quickly a short flame will light at the broiler then it lights at the orifice. I cannot get a picture but the flame is a blue flame that I cannot see the tip/end of it but I would guess it is about the 1.5 - 2" long.Is it as simple as unscrewing the broiler LP orifice a few turns?
Expert:  Kelly replied 2 years ago.

Is the broiler burner sitting correctly over the orifice?

Customer: replied 2 years ago.
As far as I can tell. I did get a couple of pictures attached. One is not lit and the other is with the orifice lit.
Expert:  Kelly replied 2 years ago.

Open the orifice hood a little bit at a time, like 1/4 turn, does it increase the flame to the burner? Are the other flames okay and get plenty large?

Customer: replied 2 years ago.
When you say open the orifice hood does that mean unscrew the orifice a bit or are you talking about what I would call the "air mixer"? In the pictures, the silver component that allows more air to mix w/gas.

all other burners and oven flames are fine.
Customer: replied 2 years ago.
Just the broiler that is a problem.
Expert:  Kelly replied 2 years ago.

The little brass orifice, I believe it takes a 1/2" wrench.

Customer: replied 2 years ago.
OK. I loosened it a turn or better and the flame is further away from the orifice. Do I just continue to loosen until the actual broiler burner lights?
Expert:  Kelly replied 2 years ago.

Yes, try it 1/4 turn at a time until the flame is out of the burner holes about 1.5". Just be sure to go slow as you open it. If you are careful, you can leave it lit and slowly turn the orifice but keep out of the flame area.

I need to go to meeting. Do I just log in and update you as I proceed tomorrow or when I can get back to it? I think I loosened it to far to fast and need to start over but don't have time to right now.
Customer: replied 2 years ago.
Any tricks as to a starting point. That is, if I start with it snug, loosen 5 turns or some such thing?
Expert:  Kelly replied 2 years ago.

Well, it is designed to be ample gas for LP with the hood screwed all the way down. So, if it took more than a full turn, it has other issues.
