The significance of the red LED (fig. 2 2, page 3)
When operational faults occur the LED flashes a number of times. The number of
pulses depends on the type of fault.
Each flash lasts for one quarter of a second. After the series of impulses a pause
follows. The sequence for the fault is repeated every four seconds.
Number of
Fault
flashes
1 Supply voltage
2 Excessive fan current
3 The motor doesn't start
4 Speed too low
5 Overheating of the
electronics unit
Continuous Temperature not measurable
Interior temperature too low in temperature level "1"
Fault
Compressor runs
constantly
Compressor runs for a
long time
30
Possible cause
Faulty thermostat
Large quantities have been frozen in
the freezer compartment
RC10.4 70, RC10.4 90
Possible cause
The supply voltage is outside of the set
range.
The fan loads the electronics unit with
more than 1 A.
The rotor is jammed.
The pressure difference in the cooling
system is too high (> 5 bar).
If the cooling system is overloaded, the
minimum speed of the motor of
1850 RPM cannot be maintained.
If the cooling system is loaded too
heavily or if the temperature is too high,
the electronics can overheat.
NTC sensor is faulty.
Remedy
Change the thermostat
