Why does my Viking VGR48-8B burner make a roaring noise like a blowtorch?
- TThomas JacksonAug 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.
