Service your Ruud UANL-037JAZ central air conditioner with genuine OEM replacement parts from Repair Clinic. The UANL-037JAZ is a 3-ton condensing unit in Ruud’s UANL series. The serial designation 7840 in some search queries refers to the production serial range for this unit and does not affect parts compatibility. Because Ruud and Rheem are sister brands sharing the same manufacturing platform, UANL-037JAZ parts are interchangeable with their Rheem equivalents at the same 3-ton UANL configuration. Parts most frequently replaced include the run capacitor, contactor, condenser fan motor, and fan blade. Use the UANL-037JAZ parts list and browse the full Ruud central air conditioner parts catalog.
Ruud UANL-037JAZ Platform: 3-Ton Output Class, UANL Series Context, and Ruud-Rheem Equivalence
The Ruud UANL-037JAZ is a 3-ton (approximately 37,000 BTU) condensing unit in Ruud’s UANL series. The 037 in the model number identifies the output class; this is a nominal 3-ton designation in the UANL series. The UANL series is distinct from the UAKB and UAMB series in Ruud’s condensing unit lineup; component interchangeability between the UANL and adjacent Ruud series at the same nominal tonnage should be confirmed from the UANL-037JAZ specific parts list rather than assumed from tonnage alone. The UANL-037JAZ manual documents the refrigerant charge specification and component locations. For diagnostic guidance, visit the Ruud air conditioner troubleshooting section.
UANL-037JAZ Component Failures and 3-Ton Service Priorities
UANL-037JAZ Capacitor Annual Testing and Dual-Section Diagnosis
The UANL-037JAZ capacitor is a dual-run unit serving the 3-ton compressor and condenser fan motor. Annual microfarad testing before cooling season is essential. A compressor that hums briefly and trips thermal protection while the fan runs normally has a failed compressor section; a fan that fails to start while the compressor runs has a failed fan motor section. Replace the capacitor when either section reads more than five percent below the rated value. Browse Ruud central air conditioner capacitor parts.
Ruud UANL-037JAZ Contactor Inspection at 3-Ton Load
The UANL-037JAZ contactor switches line voltage to the compressor and fan motor. Inspect contact faces at each annual service; replace when any pitting or erosion is visible. Find compatible options at the Ruud air conditioner contactor page.
UANL-037JAZ Fan Motor and 3-Ton Coil Airflow
The UANL-037JAZ fan motor is sized for the 3-ton condenser coil; replace at first sign of bearing noise. Confirm the UANL series output class designation when ordering to prevent substituting a motor from a different Ruud series. Browse Ruud central air conditioner fan motor parts.
UANL-037JAZ Fan Blade Annual Inspection
Inspect the UANL-037JAZ fan blade annually; confirm the blade specification from the UANL-037JAZ parts list before ordering. Browse Ruud central air conditioner fan blade parts.

Ruud UANL-037JAZ Central Air Conditioner Parts FAQ
What tonnage is the Ruud UANL-037JAZ?
The Ruud UANL-037JAZ is a nominal 3-ton condensing unit. The 037 in the model number identifies the approximately 3-ton output class in the UANL series. Fan motors and blades must be specified for the UANL-037 output class and are not interchangeable with components from other Ruud condensing unit series at the same nominal tonnage without confirmation against the UANL-037JAZ specific parts list.
How do I diagnose a dual-section capacitor failure on the UANL-037JAZ?
The UANL-037JAZ dual-run capacitor can fail in either the compressor section or the fan motor section independently. If the compressor hums briefly and then trips its thermal overload while the condenser fan continues to run normally, the compressor section has failed. If the fan fails to start while the compressor runs normally, the fan motor section has failed. Test both sections with a microfarad meter; replace the full capacitor when either section reads more than five percent below the rated value.
Are UANL-037JAZ and Rheem equivalent parts interchangeable?
Yes. Ruud and Rheem are sister brands under Rheem Manufacturing sharing the same manufacturing platform. The UANL-037JAZ and its Rheem equivalent at the same 3-ton UANL configuration are identical units. Run capacitors, contactors, fan motors, and fan blades are interchangeable across Ruud and Rheem brand designations at the same series and output class.
How do I reset the Ruud UANL-037JAZ after a tripped breaker?
After restoring the breaker, allow the UANL-037JAZ to restart normally; most Ruud condensing units have a 3 to 5 minute delay timer that prevents the compressor from restarting immediately after power restoration to allow pressure equalization. If the unit trips the breaker again immediately after reset, do not reset the breaker again; repeated breaker trips indicate a compressor or electrical fault that requires diagnosis before power restoration.
