Jeez Don, pay attention. Just as I was finishing building a smoker here I noticed it was getting a little stuttery, in hindsight it had also started throwing the circuit breakerer in the shed. I took it down to the big smoke to the manufacturer for a service. Yeah, I know, "manufacturing" means make not sell, well they "pit them together" there out of components made in low cost jurisdictions, how's that? Anyway, they told me the repair guy wasn't back for a fortnight and there was already a big backlog (and you know that if there's a shortcut I'm on it)....so I left it for repair, and bought a new fancy one. I'm an idiot.
