Why isn't the convection fan spinning?
Check first that the oven is actually set to a convection mode, because the fan only turns when the mode calls for it. If convection is selected, the oven is hot and the back wall stays silent, the motor or its bearing has given up. That is a technician's job, so book it with Viking Repair Pros of Los Angeles.
What you can see, what it means, what to do now
See it
Food browns as though nothing is moving air around it, and standing at the open door on a cold start you hear the oven click and hum but nothing whirring behind the back wall.
What it means
Most often the fan motor has failed or its bearing has seized, and a seized bearing usually announces itself with weeks of grinding first. Less often the control is not calling for the fan at all, which points at the board rather than the motor.
What to do tonight
Put the oven on a convection setting from cold and listen at the door for the first minute. If nothing turns, bake on a conventional setting for now and leave the cavity cover alone — what sits behind it is not an owner's part.
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.
Telling a stopped fan from a fan you simply cannot hear
A convection fan is quiet by design, and in a kitchen with a hood running or a room full of people it disappears completely. Start the oven cold, with nothing else on, and stand at the closed door: you are listening for a steady breath of air behind the metal, not for a motor. If you can hear it at the start of a bake and not later, that is a different story from never hearing it at all, and worth saying when you call.
A fan that stops only once the oven is hot tends to be the motor giving up as it warms. Note when it happens and how long the oven had been running, because that detail shortens the visit.

Follow-ups
Can I keep baking without it?
Yes, for ordinary baking you can. A still fan costs you evenness rather than heat, so rotate trays halfway and give things a little longer. What you should not do is keep selecting convection and hoping: if the motor is drawing current and not turning, leaving it switched on helps nobody.
