i was smugly thinking yesterday how trouble free my pax has been and sure enough i turn it on and get the temp light issue for the first time. I tried wiping the mouth piece section down with iso applying the lube and no joy. It took soaking it in the iso then the lube to work
The temp light issue comes and goes in mine. For some bizarre reason it usually happens to me right after I clean the Pax. It is really not a major issue for me, I'm used to it. The first thing you should try any time you get the problem is to remove the mouthpiece and blow through the stem. I have no idea why this works, it doesn't make any sense to me at all, and I didn't believe it would when I read about it, but it works for me about 90% of the time.
