Co2 solenoid ?

[Barebottomcorals_Ed]

My Co2 solenoid on my calcium reactor is stuck open..Any one every fix one of these before? if so how?

 

Thanks for the help in advance

When it happened to me, it was due to dust from a rusty spring coming off and causing the solenoid pin to start binding/corroding.  You could try cleaning it and maybe sanding/buffing it smooth again but it will most likely stick again very soon.  Probably not worth the effort/risk to save a few bucks for a new solenoid.  On the flip side, the new solenoid has worked for years without any problems.
