Restore your UAND-048JAZ central air conditioner running efficiently with genuine OEM replacement parts from Repair Clinic. The UAND-048JAZ is a four-ton R-22 residential outdoor condensing unit using R-22 refrigerant. Ruud and Rheem are sister brands under the same parent company. The UAND series is related to the Rheem RAKA series at similar tonnage, with the UAND designation identifying a specific Ruud cabinet configuration. The dual run capacitor, contactor, and outdoor fan motor account for the vast majority of service calls. Repair Clinic stocks genuine Ruud OEM parts for the UAND-048JAZ including the Rheem capacitor parts, Rheem contactor parts, Rheem fan motor parts, and Rheem high-pressure switch parts.

UAND-048JAZ: Four-Ton R-22 Outdoor Condensing Unit Service
Annual capacitance testing of the dual run capacitor before the cooling season is the most cost-effective preventive maintenance step for the UAND-048JAZ. Match all microfarad values from the installed capacitor label before ordering a replacement. The central air conditioner repair help section covers capacitor testing and contactor diagnosis for this platform.
Most Replaced Parts on the UAND-048JAZ
Dual Run Capacitor for the UAND-048JAZ
The dual run capacitor provides starting and running torque for both the compressor and outdoor fan motor. A reading more than 10% below the rated value causes the compressor to hard-start. Match all three microfarad values from the installed capacitor label before ordering.
UAND-048JAZ Contactor
The contactor closes the 240-volt compressor circuit at every cooling cycle start. Pitted or burned contacts generate heat that transfers to the compressor motor terminals. Replace a contactor with visibly eroded contacts before compressor winding damage occurs.
Outdoor Fan Motor for the UAND-048JAZ
The outdoor fan motor pulls air through the condenser coil. Test the run capacitor before ordering a replacement motor, as a failed capacitor produces identical slow-start symptoms at a fraction of the motor replacement cost.
High-Pressure Switch for the UAND-048JAZ
A high-pressure switch that trips repeatedly under normal ambient conditions points to a blocked condenser coil, failed fan motor, or refrigerant overcharge rather than a failed switch diaphragm.

UAND-048JAZ Parts FAQ
What is the UAND-048JAZ and what ton size is it?
The UAND-048JAZ is a four-ton R-22 residential outdoor condensing unit using R-22 refrigerant. Ruud and Rheem are sister brands under the same parent company. The UAND series is related to the Rheem RAKA series at similar tonnage, with the UAND designation identifying a specific Ruud cabinet configuration.
Why does my UAND-048JAZ hum but not start?
A unit that hums but does not start has most commonly failed at the dual run capacitor. Test the capacitor with a digital capacitance meter before testing any other component.
Is the Ruud UAND-048JAZ related to a Rheem equivalent unit?
Yes. Ruud and Rheem are sister brands under the same parent company. The UAND-048JAZ and its Rheem equivalent at the same four-ton R-22 configuration share the same platform engineering with interchangeable service components.
How often should I test the capacitor on the UAND-048JAZ?
Test the capacitor annually before the cooling season. A reading more than 10% below the rated microfarad value indicates a weakening capacitor that should be replaced before it fails under peak summer load.
