Product review (5 stars): Maytag gas solenoid
Works perfect.  This may be more expensive, but it is OEM.
I rather pay more than cheap parts.

Dryer was running, but not hot enough.  Dryer is a Maytag Naptune that is 13 year old
One of the solenoid may not be working.
Replaced both solenoids anyway and the dryer heated up like before.
