Hello Craig, do you know where to get this complete series on ammonia refrigeration system? Thanks

I see this is from a year ago so hopefully I get a reply. Solenoids # 1,3,4,&5 do not de-energize #2 never energizes and #6 works fine. I also have no bubbles coming from the bottom of my bubbler. There is ice under my liquid level control and all the way to the metering valve. I have tried everything I can think of and I'm about to just get a new purger... This thing is probably older then me..
