hey actually im going through something similar with mines. Its a vaporizer extreme i got about 1 and a 1/2 years ago. Last night it started making the continuos beeping noise, i thought i could put up with the noise, but then the vaporizer would no longer heat passed a couple hundred degrees F. Im not getting the error messege mentioned. I must admit I havent taken the "best" care of my vape and it has been mistreated a bit. Great product dont know about their customer service reputation though. i just emailed them a few minutes ago, did they respond to your email? Website says the heater has a lifetime warranty
