I've only had the Yocan UNI for 2 days and I cant get it to work. When I turn it on it blinks 3 times and everytime I press the button it blinks 3 times and does not heat up?

Hi @atktd22
Thanks for your post.
As for your UNI blinks 3 times, please check the cartridge connection with the battery, to make sure connected correctly.
Three lights flash 3 times means short-circuit protection.

During the manufacturing process, there can be some tolerance in extrusion on the center pin, and the UNI Mod does not have a spring-loaded center pin on the magnetic 510 adapters. So, when you press the button and get blinking lights, one of two things is happening:
  • The cartridge center pin is recessed and not making sufficient contact, the UNI mod can’t load the cartridge correctly, and flash 5 times.
  • The cartridge center pin is extruded and getting pushed in, causing a short, the UNI mod flash 3 times.
So, there are two ways to fix UNI Mod flash issues: switch cartridge or loosen the adapter.

Mine is also doing this. Very frustrating. Any suggestions to troubleshoot the connection or improve it? I've tried isopropyl alcohol. I've also tried two oil cartridges and a concentrate oven both with and without the air flow insert.

Mine is doing the same thing. Worked great for like a week. Then nothing, tried different carts. As far as I can tell the connection is fine. I loved this UNI for the one week it worked. Guess its time to look for something new.

Same problem here. It's 2 weeks old and I'm not a heavy smoker- a few puffs a day and it should not need cleaned so often. Starting to look like a defect.

On the contact, I put my cartridges in my pocket, and the electrode collects lint. When it screws in, fuzzies follow.
Just saw NO to the Fuzz.

you have the cart screwed too tightly to the adapter. loosen it up a bit
