Fazio92 January 26, 2011 Share January 26, 2011 (edited) Hey Everyone, So every time my regulator turns "on" (electronic solenoid) it has an awful loud buzzing noise. Is it going bad? It's still working properly. Any thoughts? Thanks -Anthony Edited January 26, 2011 by Fazio92 Link to comment Share on other sites More sharing options...
davelin315 January 26, 2011 Share January 26, 2011 Is it an electrical buzz or a grinding type of buzz? Sounds like something might be getting caught up in the mechanism that opens the valve on your solenoid. I haven't found a good one that will last me a long time yet, have gone through 3 of them, albeit 2 were used. Link to comment Share on other sites More sharing options...
Fazio92 January 26, 2011 Author Share January 26, 2011 It sounds like a very loud electrical buzz, so i'm not exactly sure if it is or is not actually electrical. Link to comment Share on other sites More sharing options...
davelin315 January 26, 2011 Share January 26, 2011 Hmmm... try seeing what kind of current it is drawing. They run off of low current from my limited understanding of electronics (you should be able to see what the wattage is by looking at the solenoid itself, I think mine has it stamped on on a metal plate or sticker). Maybe it's drawing too much and is a hazard. Link to comment Share on other sites More sharing options...
Coral Hind January 26, 2011 Share January 26, 2011 It sounds like the valve spring is compressed. You can pull the unit apart and stretch the spring back out. Link to comment Share on other sites More sharing options...
Coral Hind January 26, 2011 Share January 26, 2011 I figured you probably need more detail then that. Disconnect the power, shut off CO2 tank. Remove the regulator from the CO2 tank. Remove the nut and ring at the buttom of the solenoid. Slide the solenoid off. Remove screws at the base of the valve. The valve is a metal rod with a rubber tip and a spring. Stretch that spring back out. Put it all back together and give it a try. Link to comment Share on other sites More sharing options...
Fazio92 January 26, 2011 Author Share January 26, 2011 lol, you figured right! I will give it a try. hopefully that fixes it. I figured you probably need more detail then that.

Fazio92 January 26, 2011 Author Share January 26, 2011 So i took it apart, put it back together and the same thing. I is definitely coming from the magnet part where the electrical current comes in. I have it on one of the low power outlets on the DC8. Link to comment Share on other sites More sharing options...
Fazio92 January 26, 2011 Author Share January 26, 2011 I switched it to one of the regular DC8 outlets, same thing but not as loud, i think Link to comment Share on other sites More sharing options...
DaveS January 26, 2011 Share January 26, 2011 probably a bad electromagnet around the solenoid. Link to comment Share on other sites More sharing options...
Fazio92 January 26, 2011 Author Share January 26, 2011 Does that mean i need a whole new solenoid? probably a bad electromagnet around the solenoid. Link to comment Share on other sites More sharing options...
DaveS January 26, 2011 Share January 26, 2011 Yes. That electromagnet is the black square that the spring and piston valve goes into. Basically the wires from the plug go into the black square and wrap around a piece of ferrous metal. Apply electricity and it becomes a magnet (opposite polarity than the magnet that the piston valve) pushing the piston valve out. Link to comment Share on other sites More sharing options...
dandy7200 January 27, 2011 Share January 27, 2011 Hit the solenoid with a metal wrench. HARD. Link to comment Share on other sites More sharing options...
