[Fire button won't work and it is auto-firing]

Thank you. The joints aren't touching so I'll clean everything with ISO alcohol, I guess. Is that what I should be using, or is there some special cleaner I should get?

[Fire button won't work and it is auto-firing]

My positive pin "out" connection came loose, so I re-soldered it back on. It did not want to go back on very easily, but eventually with enough Flux, it made connection. I hooked the battery back up and the fire button is non responsive and when I use the temp up and down buttons, it start auto-firing. Help!!!! I'm leaving on a trip at the end of the week, plus this is my daily driver.
