Temp probe not ready right?

[Danbow]

Smoked some pheasant breast and they never reached IT of 160. Took them off after 3 hrs at 151 and they never got to 160. Needless to say they were toast. I figured maybe its the temp probe. Anyone have this experience? If it is the temp probe should I call Steve and get another one?

Maybe do a boiling water test (just the tip) and see what it reads.  It won't be instant so give it a few minutes to climb.
