I always suspected our outdoor grill thermometer was whacked. It always seemed to read high to me, but I thought maybe it was because of its location in the hood over the burners.
Nope.
It was whacked.
I bought a new replacement that was highly recommended and put both the old one and the new one in a 425* oven to test. The old one is on the left and the new one on the right.
The old one reads 540* in a 425* oven…that’s fubar.
Needless to say, the new one is now installed on the grill.
