How to fix a Hitachi RCUE180AG1 Chiller when the condenser fan does not operate?
- YyclarkAug 19, 2025
If the condenser fan on your Hitachi Chiller isn't working, there are several potential causes: * The current to the unit may be shut off. Try resetting the power supply line. * The fuse for the operation circuit might be blown or have faulty contact. Check for shorted components or loose connections, and tighten or replace as needed. * The contactor holding coil could be burned out or have faulty contact. Identify the cause and repair or replace the coil. * The overcurrent relay may be tripped. Remove the cause and reset the relay. * There might be low voltage. Verify the unit's voltage rating. * The motor or terminals could be shorted. Inspect the motor and terminals, repairing or replacing them if necessary.
