The 10ACC-048-230-2 is a four-ton R-22 residential outdoor condensing unit from Lennox’s 10ACC series. The run capacitor, contactor, and outdoor fan motor account for the vast majority of 10ACC-048-230-2 service calls. Annual capacitance testing before the cooling season is the most cost-effective preventive maintenance step on this platform. Repair Clinic stocks genuine Lennox OEM parts for the 10ACC-048-230-2 including the Lennox capacitor parts, Lennox contactor parts, Lennox fan motor parts, and Lennox high-pressure switch parts.

10ACC-048-230-2: Lennox Four-Ton R-22 Outdoor Condensing Unit Service
The Lennox 10ACC-048-230-2 is a four-ton R-22 outdoor condensing unit at the top of the 10ACC tonnage range. At four-ton capacity the compressor-section capacitor microfarad rating is larger than on lower-tonnage 10ACC configurations. Match all microfarad values from the installed capacitor label before ordering. The 10ACC-048-230-2 uses R-22 refrigerant requiring EPA 608 certified technicians for refrigerant circuit service. Annual capacitance testing before the cooling season catches a weakening capacitor before it fails under peak summer demand. The central air conditioner repair help section covers 10ACC capacitor testing and contactor diagnosis.
Most Replaced Parts on the Lennox 10ACC-048-230-2
Run Capacitor for the Lennox 10ACC-048-230-2
The run capacitor provides starting and running torque for both the four-ton compressor and outdoor fan motor. A capacitor reading more than 10% below its rated microfarad value causes the compressor to hard-start. Match all microfarad and voltage values from the installed capacitor label before ordering.
Lennox 10ACC-048-230-2 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 10ACC-048-230-2
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 10ACC-048-230-2
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.
Why Choose Repair Clinic for Lennox 10ACC-048-230-2 Parts
- Genuine Lennox 10ACC OEM Components: Four-ton run capacitors, contactors, and fan motors confirmed for the 10ACC-048-230-2 R-22 platform Lennox central air conditioner parts.
- 10ACC-048 vs 10ACC-036 Capacitor Distinction: The four-ton 048 and three-ton 036 capacitor microfarad ratings differ. The catalog differentiates these to prevent cross-tonnage substitution within the 10ACC series.
- R-22 Refrigerant Circuit Context: The 10ACC-048-230-2 uses R-22 refrigerant. Refrigerant circuit service requires EPA 608 certified technicians with access to reclaimed R-22.
- 365-Day Returns: Return any uninstalled Lennox part within a full year of purchase with no restocking fees.
Lennox 10ACC-048-230-2 Parts FAQ
What is the Lennox 10ACC-048-230-2 and what ton size is it?
The Lennox 10ACC-048-230-2 is a four-ton R-22 residential outdoor condensing unit from Lennox’s 10ACC series. The 048 identifies 48,000 BTU four-ton capacity, 230 identifies the 230-volt power configuration, and 2 identifies the production revision within the 10ACC-048-230 platform.
Why does my Lennox 10ACC-048-230-2 hum but not start?
A unit that hums but does not start has most commonly failed at the run capacitor, which cannot provide adequate starting torque to the compressor or fan motor. Test the capacitor with a digital capacitance meter before testing the contactor or compressor.
What refrigerant does the Lennox 10ACC-048-230-2 use?
The 10ACC-048-230-2 uses R-22 refrigerant. R-22 is no longer produced for new equipment and requires EPA 608 certified technicians for any refrigerant circuit service using reclaimed R-22 supplies.
How does the Lennox 10ACC-048-230-2 differ from the 10ACC-036-230?
The 10ACC-048-230-2 is a four-ton unit while the 10ACC-036-230 is a three-ton unit in the same Lennox 10ACC R-22 product line. The run capacitor carries different compressor-section microfarad ratings between the two tonnages. Never substitute capacitor specifications between the 048 and 036 configurations.
