780 Pro "cold weather start up"??

[Rockhead]

My Traeger is about 9 months old..about 40 smokes.
Cleaned it the other day as usual with the shop vac.
Tonight went to start it up and it showed "cold weather start up"...It did that for about 15 mins, then went to "igniting" for another 15 minutes. Then went to "pre-heating" for another 15 minutes and finally to "low temperature warning" The probe never went on and it was 75 degrees outside.
Any ideas??

Start by gently cleaning the rtd. It should look like this

And if that don't work, can you turn off the unit, unplug, and restart

Mine was dirty so I cleaned it. I noticed that mine is missing the conical tip at the end...

You need to replace your RTD probe.
