It could be a number of things, but the easiest and most obvious to check first is the broil element itself (this part)
Open the oven door and look on the top of the oven to see if you can see any kind of break or burned spots on the element itself.

As far as the orange glow I'm not sure, but I'm thinking if the broil element popped it could be shorted and sending voltage to the wrong spot.

Let us know what the element looks like.

The next steps would require a good working knowledge and comfort with working around 240v. This can be extremely dangerous if one lacks the experience.

I'd recommend calling a technician in vs. just guessing at a part.

The steps I would take if it were me looking at it to determine the correct part:
- pull oven from the wall
- using a meter, test for 240v at the terminal block (I.e. Where the wires connect to the oven from the wall)
- if 240v here, I'd unplug, remove the back panel to expose the element terminals
- plug in oven to wall
- start a bake or broil cycle
- with my meter set to Volts, carefully touch my two probes to the terminals of each element to see if there are 240v there.
- if no, I'd then research further if it were a bad control board or a bad thermal fuse.
If they are getting 240v I'd check continuity on the broil and bake elements to see if they might have blown.

If this beyond your comfort level, I strongly recommend calling a professional as 240v is no joke.

Let me know if you have questions.
