Temp stuck reading only at 188°F?

Didnt have this issue a few days ago, but everytime I start my sled it reads only 188°F.
Any ideas?

Is it on fire? Just Kidding check connection to gauge and also regulator

Un plug sensor see if it changes should either read low temp or high temp. If changes then most likely needs a new sensor.
