Daikin Commercial Chiller Repair – Condenser Fan Motor & Filter-Drier Replacement – Austin, TX 11.01.26
Setpoint Services performed commercial water chiller repairs at Bull & Bowl in downtown Austin, Texas, servicing a Daikin Applied AGZ210 air-cooled chiller operating on R-410A refrigerant. The service involved replacing a failed condenser fan motor and all six liquid-line filter-drier cores, with three filter-drier cores installed on each refrigeration circuit.
Following the replacements, our technicians verified condenser fan operation and performed refrigerant leak inspections at both filter-drier assemblies. No leaks were detected at the serviced connections. Significant debris accumulation was discovered inside the removed filter-drier assembly, indicating the need for additional refrigerant system evaluation and acid testing.
Further diagnostic testing identified refrigerant leaks at the Circuit 2 liquid-line ball valve and the discharge Rotalock connection on a Circuit 1 compressor. The Circuit 2 sight glass also exhibited flashing during operation, and the controller's alarm history showed previous high condenser pressure and low evaporator pressure faults.
Additional inspection revealed a water distribution pump that had tripped and required resetting, along with pump-down controls that were not functioning as expected. The remaining pump maintained water circulation during the service visit.
The approved condenser fan motor and liquid-line filter-drier replacements were completed. Additional refrigerant leak repairs, acid testing, water pump diagnostics, and pump-down control repairs were identified for further evaluation and separate authorization. This service was part of ongoing commercial chiller maintenance and refrigeration system troubleshooting at Bull & Bowl in Austin, Texas.
