My external temperature sensor display has been playing up lately. It's been reading anywhere up to 59 deg C, when the outside temperature has been down to - 8 deg C. The display has now stopped functioning altogether and is now completely blank.
Does this indicate that the external sensor is faulty, or perhaps there is an open circuit / high resistance between the sensor and the display ?
Has anyone had a similar experience ?
