“E2” When this occurs, there are also two
possible situations. The first and most likely is
that the probe circuit has a discontinuity. This
may occur as a result of a cut cable, bad
termination at the circuit board or damaged
sensor. Check the cable terminal making sure
the wires are correctly inserted into the
connector on the board. Secondly, “E2”
represents an over range reading, meaning the
temperature at the sensor has risen above the
measurable specified limit of the unit.
