I'll provide my feedback here in case it is helpful, but I agree that you should contact Dynavap about this. If you hold the cap close to your ear and shake it you should hear a small rattling sound...I'm guessing you will hear this since your cap is clicking, but check anyway. Regarding the 3 clicks: I may know what you're talking about here. On my caps I've noticed sort of a pre-click...it's not really a "click" but there is a subtle sound I can hear when it is almost ready to click, perhaps this is what you are hearing. Because sometimes I hear the pre-click, then the click, and then the second click, so 3 there. As far as it never clicking, well that is just not right...what kind of Lotus are you using? Maybe it is heating up so fast and the clicks are being masked by the sound of the torch? Try going with a slower heat up, hold flame further away, and try to feel the click in your hand. When I'm playing music loud or something, sometimes I need to feel the click instead of hear it.
When I first got my cap I always tried to wait for the second click before hitting, but I soon realized that was a mistake, because I was frequently combusting. One click is all you need...a real click, not a "pre-click". There is also a difference in sound between all 3 clicks...the pre-click is super quiet and the first click is usually quieter than the second.
