Hot Rod sometimes works sometimes not

[Hansfanz]

Hi,

Living in the Netherlands with a Traeger Pro 22. And now my hot rod fails.
Sometimes it works sometimes not. It depend per session. Nothing else.

I replaced it already, but connectiong it directly to the net confirmed that it still works fine.

I can change my controller, but I need the Celcius version. Does anybody know how to solve or get a controller in Celcius?

Thanks,

Hans
