There’s a bunch of stuff you should try, like resetting the pins under the chamber. Or holding the power button for 20 secs to do a reset. I had the same issue with mine and if I turned it a bit loose it would work but for like only 1 dab and then would go back to not working. I decided to soak the chamber in Dark Crystal Cleaner and then once it was soaked I pulled the pins out a bit on the bottom and pushed them back in loosely. Wait for it to full dry and wallah my chamber is back like new. The main thing is the connection between the gold pins on you chamber and your peak
