flash on the screen
Causes
The temperature detected by
the evaporator probe is lower
than the established value.
The temperature detected by
the cold room probe is higher
than the established value.
There has been a power
failure.
The temperature detected by
the condenser probe is higher
than the established value.
The temperature detected by
the condenser probe is higher
than the established value.
Causes
 The wrong type of probe is
installed.
 The probe is faulty.
 The probe – circuit board
connection is incorrect.
 The temperature detected
by the probe is out of the
limits accepted by the cold
