Why does my Viking Ranges burner make a roaring noise like a blowtorch?
- J
  Julia RamirezAug 8, 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 VGSS300 burner makes a popping sound when I turn it off?

  George RogersAug 17, 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 VGSS300 Ranges flashback?
- C
  Colleen WatsonAug 28, 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.
