Mailbag: How do the Valve Coils in a Gas Dryer Work?

Jeremy wrote:

I am trying to fix my Whirlpool Dryer. The dryer will not ignite the burner.
I am suspecting the gas valve, but I have a question before I purchase it. Do
both solenoid coils need to be energized at the same time? Both coils do
switch on, but not at the same time. Am I barking up the wrong tree?

Thank you.

Come bark up the Samurai’s Tree of Knowledge and read my Appliance Repair Revelation on this very subject: Burner Operation in a Gas Dryer.

“Arf!” he said.
