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.
