One of the most common causes I¡¯ve seen of stuck attenuator sections is decomposing o-rings caused by attempts to clean the attenuator contacts with chemicals that attacked the o-rings. They become sticky like glue and will latch an attenuator section inline no matter what the solenoid does.?
A broken or damaged push rod will have the same effect.?

Incidentally, if anyone can explain why partially perished o-rings which are still in-situ can cause problems to the functioning of these attenuators I'd like to be disabused of my ignorance on the matter!
