Viking VDSC548T Code Runaway Oven Temperature: Small Oven Far Above Set Point

What Runaway Oven Temperature means

On the 18-inch secondary oven of Viking VDSC548T ranges, such as the VDSC548T-4GQ or VDSC548T-6B, this condition is shown by lights rather than text: the clean light stays on and the cycle light flashes nine times. It means the oven temperature went well past the set point, above 650F for more than 10 minutes with the door unlocked. The control stops heating to protect the range.

Common causes of Runaway Oven Temperature

Temperature sensor reading low while the oven heats
Relay or element staying on
Control board not switching heat off

✓ One safe check you can try

1. Turn the small oven off. 2. Keep the door closed and do not open it while it is hot. 3. Let it cool completely. 4. Switch the range breaker off. 5. Call us before you use that oven again, because an overheat should be checked in person.

! Why to stop there

Overheating can damage the oven and the cabinets around it
The sensor, relays and control must all be tested
A repeat of the same condition could happen on the next use

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Runaway Oven TemperatureRunaway Oven Temperature questions

What does nine flashes mean?

Count nine flashes of the cycle light with the clean light on. It shows the oven went far above its setting, over 650F for more than 10 minutes with the door unlocked.

Is it safe to open the door?

Wait until the oven is completely cool. Opening a very hot oven risks burns, and fresh air can feed a hot oven. Switch it off at the breaker and keep the door shut.

Will the other oven work?

The main oven may still work, but we advise leaving the whole range off until we check the cause. We quote the price in writing first, with a 30-day workmanship warranty.
