Table 8-4 Fan troubleshooting

Fault

Type

Possible Cause

Solution

The fan

does not

rotate.

Check whether the

power supply voltage

meets the

requirements.

Check the power supply voltage.

Open phase occurs.

The voltage is less

than the lower

threshold or greater

than the upper

threshold.

A short circuit exists

between the fan and

the ground.

Check the power cable and voltage of the

motor.

The coil is short-

circuited or the

motor is burnt.

Replace the fan. If there is a beam for

hoisting the fan in the air exhaust section,

before removing the fan, use a hook to

secure the fan to the beam to prevent the

fan from falling.

The overtemperature

protection function

of the motor is

triggered (the motor

is overheated).

Check whether the air circulation is normal.

Clear foreign matters if necessary.

The fan blade is blocked or dirty.

Check the ambient temperature of the fan.

Check the voltage.

The fan blade is

blocked or dirty.

Power off the motor and prevent it from

being connected again.
● Check whether the motor is powered off.
● Clear foreign matters or contaminants.

The airflow direction

is incorrect (the

direction of the

motor is opposite to

that of the high-

speed airflow).

Check the airflow direction (rotation caused

by airflow reversal).

The fan

rotates

slowly.

Fan blade friction/

collision

Clear foreign matters or dirt in the fan if

necessary.

The active

temperature

management

function is enabled

Check whether the air circulation is normal.

Clear foreign matters if necessary.

The fan blade is blocked or polluted.
