5. If the temperature display shows "E7": there is connection problem with the sensor in the cooling
compartment. Replace the sensor.
6. If the temperature display shows "E8": there is a problem with the sensor in the cooling
compartment short circuiting. Replace the sensor.
If the display shows 37°C, 99F or a "continuous" symbol on some models that have an old version of
the control panel, replace the sensor.
7. If the temperature display shows "HI" (with regard to: AV143X3Z): "HI" on the display indicates
that the device's internal temperature is above 23°C after ten hours of operation.
Complete the following checks:
1. Connect and disconnect the device to the wall socket.
Adjust the temperature of the top and centre compartments to 5°C, the lower compartment
to 12°C (on models with three areas) or the top one to 5°C and the lower one to 12°C
(models with two areas).
2. Leave the device to operate empty for two to three hours.
After having completed these tasks:
1. If the external ventilator and the compressor are working correctly but the two or three
areas are not reaching the previously stipulated temperatures there is a gas leak or an
obstruction on the circuit.
2. If the higher compartment reaches the required temperature (on models with three areas) or
the other compartments (on models with two areas) cannot reach the temperature despite
all of the ventilators working correctly, the refrigeration valve is causing the problem and in
this instance should be replaced.
Inconsistent symbols on the display (compression cabinets):
Start by disconnecting the device for several minutes by removing the plug from the power supply
and then plugging it in again.
Sometimes this is enough to reboot the device.
Please note that if the power supply is disconnected for a prolonged period, the factory settings are
restored.
Otherwise replace the control and display panels. (Only to be completed by specialist technicians)

If the temperature display shows “EH or EL” the sensor is faulty. Replace the sensor.
