Why does my Viking Ranges burner make a roaring noise like a blowtorch?
- J
  jcoffeyAug 17, 2025
  The roaring noise, like a blowtorch, indicates a flashback, where the air/gas mixture ignites inside the burner. This could be due to several reasons. The burner might be underrated, in which case you should check the orifice size and increase it if necessary, or increase gas pressure. You may need to adjust the air shutter to reduce primary air. If the flashback occurs when the burner valve is in the off position, the valve is likely leaking and needs to be changed. If these corrections don't work, the burner may need to be replaced.

What to do if my Viking VGRC485 burner makes a popping sound when I turn it off?
- G
  Gary BenderAug 20, 2025
  If your Viking Ranges burner makes a popping sound when you turn it off, it's likely an extinction pop, which is a small explosion of gas in the burner head. This is similar to a flashback. You can try to reduce the primary air supplied to the burner, but be careful not to allow yellow tipping during burner operation. Also, check the orifice size and gas pressure.

How to fix Viking VGRC485 Ranges flashback?
- J
  Jaime BrockAug 22, 2025
  To fix a flashback in your Viking Ranges, where the air/gas mixture ignites inside the burner creating a roaring noise, start by checking the orifice size. Increase it if necessary, or increase the gas pressure. Adjust the air shutter to reduce primary air. If the flashback occurs even when the burner valve is off, the valve is probably leaking and needs replacement. As a last resort, replace the burner if the previous steps fail.

Viking Ranges self-clean not working, door won't lock, but power is present. What's wrong?
- T
  Theresa DavisSep 2, 2025
  If your Viking Ranges is not self-cleaning, the bake and broil functions are normal, the door won’t lock, but 120 VAC is present to the door lock module/timer, there's no motor movement, and the clean light is on, it could be due to: * Open relay contacts on the door lock module/timer. * Open contacts on the auto reset thermostat. * Open windings in the lock motor. To fix this, you might need to replace the door lock module/timer, the auto reset thermostat, or the lock motor assembly.

Why is there no air circulation during convection cook on my Viking VGRC485?
- A
  Alexander FrancisSep 6, 2025
  If the convection cook function heats in your Viking Ranges, but there's no air circulation, it could be due to: * An open winding in the convection fan motor. * A frozen motor shaft. * An open selector switch contact. To resolve this, you might need to replace the fan motor or the selector switch.

What causes the door lock motor to keep running on my Viking VGRC485?
- J
  Joshua HansenSep 8, 2025
  If the door lock motor continues to run on your Viking Ranges, there's no signal to the sensor, and the clean light is on, it could be because the SW2 switch on the door lock mechanism is not closing. To fix this, you may need to adjust the SW2 switch position or replace the faulty switch.

Why is there no heat when the door lock motor is engaged on my Viking VGRC485?
- D
  Donald RobinsonSep 12, 2025
  If the door lock motor is engaged on your Viking Ranges, there's a signal to the sensor, but there's no heat and the clean light is on, it could be that the door lock module/timer relay is not closing. To resolve this, you may need to replace the PC board.
