Why does the preheat light never go off?
The light is not the problem. On most ovens the preheat indicator stays lit until the control reads the cavity at the number you set, so a light that never clears is telling you the oven never got there. Treat it as a heating fault, and Viking Repair Pros of Los Angeles can measure where it stalls.
What you can see, what it means, what to do now
See it
The preheat symbol or word stays on the display long after the oven should be ready, and the tone that normally announces it never sounds. Food put in on time comes out pale and underdone.
What it means
The oven decides for itself when preheating has finished, and it decides on what its sensor reports. A cavity that climbs slowly and then settles below the setting keeps the indicator lit for ever. The usual reasons are a tired element or burner, a sensor reading high, or heat escaping past a door that no longer shuts tight.
What to do tonight
Set a lower temperature than usual and watch whether the indicator ever clears. If it does, you know the oven is reaching some numbers and not others, which is worth saying when you book. Cook nothing you cannot afford to lose while it behaves like this.
Still doing it after that? Call Viking Repair Pros of Los Angeles on (213) 652-7030. The $89 visit covers the fault-finding and comes off the repair.
Why this is a heating question, not a lighting one
It is tempting to treat the indicator as the broken thing, because it is the only part of this you can see. It is not. On most controls that lamp is driven by the same reading the oven uses to decide it is ready, so it is a faithful report of something you would otherwise have no way of knowing.
That makes it useful. An oven that gets close and takes an age to finish is a different problem from one that plateaus well short and sits there. The first points at a heat source that is tiring, or at a cavity losing warmth past a worn seal; the second more often points at what is measuring the cavity in the first place. A technician settles it by watching the cavity with an instrument of their own while the oven’s own reading sits on the display beside it.

Follow-ups
Can I just ignore the light and cook anyway?
You can, but you are cooking blind. Everything in the cavity is being held at whatever temperature the oven managed to reach rather than the one you chose, so times stop meaning anything and results wander. Use an oven thermometer if you have one, and book the visit before a day you need the oven.
