Keep your RAKA-048JAZ central air conditioner running efficiently with genuine OEM replacement parts from Repair Clinic. The RAKA-048JAZ is a four-ton R-22 residential outdoor condensing unit. The unit uses R-22 refrigerant requiring EPA 608 certified technicians for any refrigerant circuit service. Rheem and Ruud are sister brands under the same parent company, and all service components are interchangeable between both brand designations at the same configuration. The dual run capacitor, contactor, and outdoor fan motor account for the vast majority of service calls. Repair Clinic stocks genuine Rheem OEM parts for the RAKA-048JAZ including the Rheem capacitor parts, Rheem contactor parts, Rheem fan motor parts, and Rheem high-pressure switch parts.

RAKA-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 RAKA-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 RAKA-048JAZ
Dual Run Capacitor for the RAKA-048JAZ
The dual run capacitor provides starting and running torque for both the compressor and outdoor fan motor in a single can. A capacitor reading more than 10% below its rated microfarad value causes the compressor to hard-start, accumulating heat in the motor windings. Match all three microfarad values from the installed capacitor label before ordering.
RAKA-048JAZ Contactor
The contactor closes the 240-volt compressor power circuit at every cooling cycle start. Pitted or burned contact surfaces 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 RAKA-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 RAKA-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.

RAKA-048JAZ Parts FAQ
What is the RAKA-048JAZ and what ton size is it?
The RAKA-048JAZ is a four-ton R-22 residential outdoor condensing unit from Rheem’s RAKA series. The unit uses R-22 refrigerant requiring EPA 608 certified technicians for any refrigerant circuit service.
Why does my RAKA-048JAZ hum but not start?
A unit that hums but does not start has most commonly failed at the dual run capacitor, which cannot provide adequate starting torque to the compressor or fan motor. Test the capacitor with a digital capacitance meter before testing any other component.
How does the Rheem RAKA-048JAZ differ from the RAKA-042JAZ?
The RAKA-048JAZ is a four-ton unit while the RAKA-042JAZ is a three-and-a-half-ton unit in the same Rheem RAKA R-22 product line. The dual run capacitor carries different compressor-section microfarad ratings between the two tonnages. Never substitute capacitor specifications between the 048 and 042 configurations.
How often should I test the capacitor on the RAKA-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.
