Restore efficient cooling from your Ruud UAKB-024JAZ central air conditioner with genuine OEM replacement parts from Repair Clinic. The UAKB-024JAZ is a 2-ton single-stage cooling-only condensing unit in Ruud’s UAKB series, one capacity class below the 2.5-ton UAKB-030JAZ. The serial prefix 6950 in the UAKB-024JAZ/Serial: 6950 designation identifies the production date range; for most service components including the run capacitor, contactor, fan motor, and fan blade, this serial prefix does not affect parts compatibility. Because Ruud and Rheem share a manufacturing platform, UAKB-024JAZ parts and equivalent Rheem RAKA-024-series components at the same 2-ton class are interchangeable. Parts most frequently replaced on the UAKB-024JAZ include the run capacitor, contactor, fan motor, and fan blade. Use the UAKB-024JAZ/Serial: 6950 parts list and the full Ruud central air conditioner parts catalog to confirm fit.
UAKB-024JAZ at 2 Tons: Output Class Differences from the UAKB-030JAZ and Serial Date Context
The Ruud UAKB-024JAZ is a 2-ton (24,000 BTU) condensing unit, one capacity class below the 2.5-ton UAKB-030JAZ. While both share the UAKB platform generation, the fan motor, fan blade, and condenser coil are sized for their respective tonnage outputs and are not interchangeable between the 024 and 030 configurations; always confirm the 024 designation when ordering motors or blades for the UAKB-024JAZ. The serial prefix 6950 in the UAKB-024JAZ/Serial: 6950 designation encodes the production week and year. For run capacitors, contactors, fan motors, and fan blades, the serial date has no impact on parts selection. For control boards and wiring harnesses, confirm that the serial range is covered in the listing before ordering. Ruud and Rheem share a manufacturing platform, and equivalent Rheem RAKA-024 components at the same 2-ton output class are interchangeable with UAKB-024JAZ parts.

UAKB-024JAZ Failure Patterns at the 2-Ton Output Class
UAKB-024JAZ Run Capacitor Microfarad Loss and Compressor Overload Symptoms
The run capacitor on the UAKB-024JAZ is a dual-run unit serving the compressor and condenser fan motor from a single housing. At 2-ton output, the compressor motor is smaller than in 3-ton or 4-ton units, which means it has less thermal mass to absorb the elevated amperage draw that a degraded capacitor produces during each start. A 2-ton compressor running against a degraded capacitor trips its internal thermal overload protector sooner and more frequently than a larger compressor under the same capacitor degradation level. If the UAKB-024JAZ starts and then shuts off within minutes of beginning a cooling cycle on a hot day, test the capacitor before any other component; this is the most common cause of this symptom pattern at the 2-ton output class. Browse Ruud central air conditioner capacitor parts for the correct 024-class replacement.
UAKB-024JAZ/Serial: 6950 Fan Motor and 2-Ton Airflow Matching
The UAKB-024JAZ fan motor is sized for the 2-ton condenser coil’s airflow requirement. A fan motor from the UAKB-030JAZ configured for a larger coil will not produce correct airflow balance in the 024 cabinet, potentially over-pressurizing the coil and reducing heat rejection efficiency. Confirm the motor’s rated RPM, horsepower, and blade diameter specification from the UAKB-024JAZ/Serial: 6950 parts list before ordering a motor replacement. A motor with degraded bearings running below rated RPM in the 024 configuration has a proportionally larger impact on cooling capacity than the same bearing degradation in a larger 3-ton or 4-ton unit, because the 2-ton system has less heat rejection margin. Browse Ruud central air conditioner fan motor parts.
UAKB-024JAZ Fan Blade Replacement: Balance, Pitch, and Hub Specification
The fan blade on the UAKB-024JAZ/Serial: 6950 drives airflow through the 2-ton condenser coil and must be correctly balanced and pitched for the fan motor’s rated RPM. A blade with a bent tip, surface corrosion along a vane, or a crack at the hub creates imbalance that vibrates the motor shaft bearing, shortening bearing life from the typical several years to a matter of months under sustained vibration. Inspect the blade whenever the fan motor is being serviced and replace it if any damage is found. Confirm the blade diameter, pitch angle, and hub bore dimension from the UAKB-024JAZ/Serial: 6950 parts list before ordering; a blade matched to diameter but with incorrect pitch produces inadequate airflow despite physical installation. Browse Ruud central air conditioner fan blade parts.
Contactor Switching Cycle Accumulation on the Ruud UAKB-024JAZ
The contactor on the UAKB-024JAZ Central Air conditioner switches line voltage to the compressor and fan motor at every thermostat cooling cycle. Arc erosion on the contact faces builds progressively through the operating life of the unit, increasing contact resistance and dropping the effective voltage delivered to the compressor motor below nameplate specification. A 2-ton compressor receiving reduced voltage due to a worn contactor runs at higher winding temperature and trips its thermal overload more readily than it would at correct voltage. Inspect the contactor contact faces at each annual service and replace when any pitting or face erosion is visible, regardless of the unit’s age. Find compatible parts at the Ruud air conditioner contactor page.
Condenser Coil Cleaning Frequency on the 2-Ton UAKB-024JAZ
The condenser coil on the UAKB-024JAZ rejects compressor heat to the outdoor air stream. In a 2-ton unit, the coil surface area is smaller than in 3-ton or 4-ton configurations, meaning that an equivalent debris load on the fins has a proportionally larger impact on airflow restriction and condensing pressure elevation. Annual coil cleaning at the start of cooling season is the minimum recommended interval; in locations with heavy cottonwood, pet hair, or dense landscaping adjacent to the unit, cleaning every 90 days during the cooling season maintains the heat rejection efficiency the 2-ton compressor requires to operate within its design pressure range.

Ruud UAKB-024JAZ Central Air Conditioner Parts FAQ
Can I use a UAKB-030JAZ fan motor or fan blade in my UAKB-024JAZ?
No. The UAKB-024JAZ fan motor and fan blade are sized for the 2-ton (024) condenser coil’s airflow requirement. A motor or blade from the 030-class (2.5-ton) configuration is not matched to the 024 coil surface area and will produce incorrect airflow, potentially raising condensing pressure above the 2-ton compressor’s design operating range. Always confirm the 024 designation when ordering motors and blades for the UAKB-024JAZ.
What does the Serial: 6950 prefix mean for UAKB-024JAZ parts ordering?
The 6950 serial prefix identifies the production week and year of manufacture for this specific unit. For run capacitors, contactors, fan motors, and fan blades, the serial prefix has no impact on parts compatibility within the UAKB-024JAZ model. For control boards and wiring harnesses, confirm the serial range is covered in the specific part listing before ordering to ensure the correct production generation component.
Why does the UAKB-024JAZ shut off quickly on hot days even after the capacitor was replaced?
If the UAKB-024JAZ still shuts off quickly on hot days after a capacitor replacement, inspect the condenser coil for debris restriction reducing airflow and elevating condensing pressure, the contactor for face erosion dropping supply voltage to the compressor, and the fan blade condition and seating on the motor shaft. A blade that is not fully seated wobbles at speed, reducing effective airflow below what a correctly seated blade produces even with a new motor.
Is the Ruud UAKB-024JAZ the same unit as a Rheem RAKA-024 condensing unit?
Yes. Ruud and Rheem are the same manufacturer producing units under two brand labels. The UAKB-024JAZ and its Rheem RAKA equivalent at the 2-ton output class are the same physical unit. Run capacitors, contactors, fan motors, and fan blades are interchangeable between the two brand designations at the same output class with no modification required.
