Error description
Possible cause or solution

 
E03.0-

Fan malfunction
(excessive
temperature in the
motor winding)
 thermoprotection
contact has tripped
 Fan 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) F10 fuse (6,3 A or 10 A for
floor models) has tripped
e) Thermoprotection contact in the motor winding
(bi-metallic strip) defective or interrupted
