RN4081 atty.

[Jim Davis]

Hey guys,

I'm playing with a RN4081 atty that went cold on me. I thought I'd check it out before I dissect it.

It has continuity, so I believe the coil is still good.
The new attys show me 3.5 ohms.
The dead one gives me 85k ohms, leading me to believe that the coil may be shorted with excessive gunk.

Sound right to you?

Your atomizer is going to die just by you trying to get it to produce vapor. Not being an electrical engineer, it seems that something is impeding the flow of current through the atomizer coil. I have an NJOY atomizer going back to NJOY just for this reason.

If you are unable to return the atomizer for replacement under a warranty, try some of the less aggressive cleaning procedures in various threads on this forum. When I kill and atomizer, it is dead. So, I cannot recommend a cleaning/revitalizing procedure.

85k ohms is a burned out atomizer.

They start at about 3.5 ohms when new
as they get older the resistance can increase causing poor function.

I have enough spares, but I like to make sure it's totally dead. If so, I'll disect it, and see what I can find. I won't throw it away if I know I can get one more puff out of it.

I suspected as much. I guess I won't get that extra puff out of it.

Nice to know!

at 85k ohms it sounds like the connection is broken at the coil and the reading is just through the carbon buildup. Just a guess but that is a lot of ohms.

Hey Jim, did the new bunch of atty's you got have a large hole or a small one. I noticed a big difference in the two different kinds. My original was the big hole, probably why I love my 4081 so much. I am looking for spares to order but I don't want the tiny holes.

That's exactly what happened. I pulled the bridge, and the coil was broken inside the gunk. I put it aside. When I get a chance, I'll wind a new coil, and see how hard it is to get that tiny thing in the atty. I think replaceable coils would be the answer.

Actually never paid attention. I'll have to check mine out the next time I make it home. I got 25 more waiting for me at the house.
