Cause
Check method and remedy
(1)
Overcurrent relay (51F) trip
Check the fan for proper rotation. Check for worn bearings and pulley contacts.
Check the V-belt for proper tension. (Check for over-tightening.)
Check the motor for proper rotation.
51F malfunction (with the test switch being left to ON)
(2)
Blown fuse (F1)
Check for blown or loose fuses.
(3)
Auxiliary relay (X4) fault
Loose lead wire, broken wire, miswiring
Coil fault, contact failure
(4)
Broken wire
Check for broken wires.
(5)
Loose connector
Check the connectors for proper contact.
(6)
Indoor unit control board
(I.B.) fault
If the above items are all normal and the problem persists, circuit board failure is
suspected.
4115
Cause
Check method and remedy
(1)
Power supply error
Check the voltage of the power supply terminal
block (TB1).
(2)
Noise filter problem
Coil problem
Circuit board failure
Check the coil connections.
Check for coil burnout.
Confirm that the voltage at the CN3 connector is
198 V or above.
(3)
Faulty wiring
Check fuse F01 on the control board.
(4)
Wiring failure
Between noise filter CN3 and noise filter CN2 and con-
trol board CNAC
Confirm that the voltage at the control board con-
