Kitchen Gas Appliances - gas dryer

Hello craigt. Welcome to my Gas Appliances forum and our Do-It-Yourself Web Site.

The white powder substance is usually harmless. It a by product of sulfur in natural gas and has the tendency to coat or line the burner area.

Usually the residual isn't a large buildup. Cleaning resolves the problem for a long time to come. There is no cause for alarm with this condition and there isn't any means to correct it. Nor is it an indication of a problem with the appliance.

DRYER SERVICE TIP & REMINDER:
It's always adviseable to clean the entire exhaust venting system every 2 years and or during any dryer maintenance, service and or repairs.
