I have a Matag mdg9420bww gas dryer… Maybe 6 yrs old… Will start up and heat fine for about 5 minutes then the flame goes out and every few minutes the ignighter will glow but no gas. Checked the exaust and it was OK.

replace the coils on the gas valve, and that should do the trick. let me know how it goes. tom [url=]applianceeducator.com - parts[/url]
Amazing!!! The coils did it. It’s alive again! $23.00 and knowing what to replace. This forum rocks.
Thanks
