UAKB-018JAZ: One-And-A-Half-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 UAKB-018JAZ. 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 UAKB-018JAZ
Dual Run Capacitor for the UAKB-018JAZ
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.
UAKB-018JAZ 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 UAKB-018JAZ
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 UAKB-018JAZ
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.

UAKB-018JAZ Parts FAQ
What is the UAKB-018JAZ and what ton size is it?
The UAKB-018JAZ is a one-and-a-half-ton R-22 residential outdoor condensing unit using R-22 refrigerant. Ruud and Rheem are sister brands under the same parent company. The UAKB-018JAZ is the smallest standard tonnage in the Ruud UAKB series, with all service components fully interchangeable with the Rheem equivalent.
Why does my UAKB-018JAZ 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 UAKB-018JAZ related to a Rheem equivalent unit?
Yes. Ruud and Rheem are sister brands under the same parent company. The UAKB-018JAZ and its Rheem equivalent at the same one-and-a-half-ton configuration share the same platform engineering with interchangeable service components.
How often should I test the capacitor on the UAKB-018JAZ?
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.
