Error description
Possible cause or remedy
E03.0-
0-0
Fan malfunction
(excessive
temperature in the
motor winding)
thermoprotection
contact has tripped
• Fan motor has excessive temperature in the winding
a) One phase is missing from the power connection
b) Fan motor is defective
c) One phase is not connected through from the
contactor
d) Microfuse F10 (6.3 A or 10 A for floor models)
has tripped
e) Thermoprotection contact in the motor winding
(bi-metallic strip) defective or interrupted
