Keep your Rheem RRKA-A030 packaged Unit/RTU operating efficiently with genuine OEM replacement parts from Repair Clinic. The RRKA-A030 is a 2.5-ton cooling-only packaged rooftop unit from Rheem’s RRKA commercial series, designed for rooftop installation on commercial and light-commercial buildings. As a cooling-only unit the RRKA-A030 does not include a built-in heating section and must pair with a separate building heating system. The dual run capacitor, contactor, and blower motor account for the majority of RRKA-A030 field service calls. Repair Clinic stocks genuine Rheem OEM parts for the RRKA-A030 including the Rheem capacitor parts, Rheem contactor parts, Rheem blower motor parts, and Rheem control board parts.

RRKA-A030: Rheem 2.5-Ton Cooling-Only Commercial Packaged Rooftop Unit Service
The Rheem RRKA-A030 is a cooling-only packaged unit, distinct from the Rheem gas-electric RTU models that include a gas furnace section in the same cabinet. The RRKA series serves the cooling function only, and building heating is provided by a separate system. Because the RRKA-A030 operates continuously throughout the cooling season on rooftop installations exposed to direct sunlight and ambient heat, the dual run capacitor accumulates proportionally more thermal stress than in ground-mounted split-system applications.
Most Replaced Parts on the Rheem RRKA-A030
Dual Run Capacitor for the Rheem RRKA-A030
The dual run capacitor provides starting and running torque for both the compressor and the condenser 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 with every cooling cycle. On a rooftop unit exposed to direct sunlight, capacitor thermal stress is higher than in shaded split-system applications. Annual testing before the cooling season is the most cost-effective preventive step.
Contactor for the RRKA-A030
The contactor closes the 240-volt or higher compressor power circuit at every cooling cycle start. Pitted or burned silver-alloy contact surfaces increase circuit resistance and generate heat that transfers to the compressor motor terminals. On a commercial rooftop unit that cycles frequently throughout the business day, contactor contact erosion accumulates faster than in residential applications.
Blower Motor for the Rheem RRKA-A030
The blower motor circulates conditioned air through the building ductwork. Test the run capacitor before ordering a replacement motor. A failed capacitor produces identical slow-start symptoms at a fraction of the motor replacement cost.
Control Board for the RRKA-A030
The control board manages the cooling sequence, safety switch monitoring, and thermostat interface on the RRKA-A030. Read any available diagnostic outputs or LED codes before ordering a replacement board to confirm the board rather than a low-voltage wiring fault is responsible for the symptom.

- 365-Day Returns: Return any uninstalled Rheem part within a full year of purchase with no restocking fees.
Rheem RRKA-A030 Packaged Unit Parts FAQ
What is the Rheem RRKA-A030 and what does the model number decode to?
The Rheem RRKA-A030 is a 2.5-ton cooling-only packaged rooftop unit. RRKA identifies the Rheem commercial packaged cooling-only series, A identifies the efficiency revision, 030 identifies 30,000 BTU 2.5-ton cooling capacity, and A identifies the cabinet and electrical configuration suffix.
What is the difference between a cooling-only packaged unit and a gas-electric packaged unit?
A cooling-only packaged unit like the RRKA-A030 provides only air conditioning with no built-in heating source. It must be paired with a separate heating system such as a gas furnace or electric heat strips installed in the building ductwork. A gas-electric packaged unit contains both a cooling system and a gas furnace section in the same cabinet.
Why is my Rheem RRKA-A030 running but not cooling the building?
A packaged unit that runs but does not cool is most commonly caused by a failed dual run capacitor preventing the compressor from starting, burned contactor contacts interrupting the compressor power circuit, a low refrigerant charge, or a failed compressor. Test the capacitor first using a digital capacitance meter before proceeding to other diagnoses.
How do I access the components inside the Rheem RRKA-A030 for service?
The RRKA-A030 is a rooftop unit with removable service panels on multiple sides of the cabinet. Access the electrical controls and contactor through the control access panel. Access the compressor and refrigerant connections through the compressor compartment panel. Always disconnect power at the unit disconnect switch before opening any access panel.
