Fan Motor1 Fault
F031
1. Motor is in locked-rotor state
2. Wire connection between DC-
fan motor module and fan motor
is in bad contact
1.
Change a new fan motor
2.
Check the wire connection and
make sure they are in good contact
Low ATProtection
TP
Ambient temp is too low
Fan Motor Fault
F032
1. Motor is in locked-rotor state
2.Wire connection between DC-
fan motor module and fan motor
is in bad contact
1.
Change a new fan motor.
2.
Check the wire connection and
make sure they are in good contact.
