I'm getting lots of the temp light issue now though I feel my Pax is thoroughly clean. Haven't tried the lube yet (and not fond of the idea), but yet I gotta hold the mouthpiece super still and just so for the heater to actually warm up (and after warm it usually quits acting up so horribly).
I still haven't actually got the spring out to clean, though I've tried to follow the hints others have left, though I don't have the MFLB brush some have had success with.
Any last minute suggestions before calling Ploom? For this much money the on/off functionality shouldn't be this broke..
I don't have a pax yet so i am not in as much of a place to speak, but I noticed you mentioned you haven't even taken out the spring to clean it yet? Look at page 331. Look at the picture of how dirty the spring is. If you clean off the spring it and it works again let us know!
My whole purchase of a used Pax is a bet on hoping that keeping it 100% clean will keep it running well without needing to get replaced! Hope I don't lose it
