Are you sure you didn't turn it off? I think if you hit one of the buttons
the correct number of times the display turns off?
If you get wildly wrong temperature readings, it needs a new sensor. If
the display is blank and it's not turned off, you need a new unit. But
first, check the fuses and wiring!
