Keep your ICP N4A342AKA300 central air conditioner running efficiently with genuine OEM replacement parts from Repair Clinic. The N4A342AKA300 is a 3.5-ton single-stage cooling-only condensing unit in ICP’s N4A series. ICP (International Comfort Products) markets this platform under the Heil, Tempstar, WeatherKing, and Arcoaire brand designations as well; parts ordered under any of these ICP brand channels at the same 3.5-ton N4A342 configuration are interchangeable. The n4a342aka300 tonnage is 3.5 tons, confirmed from the 342 capacity tier in the model number. Parts most frequently replaced include the run capacitor, contactor, condenser fan motor, and fan blade. Use the N4A342AKA300 parts list and browse the full ICP central air conditioner parts catalog.
N4A342AKA300 on the ICP Platform: 3.5-Ton Output Class, Tonnage Confirmation, and AKA vs AKN Revision
The ICP N4A342AKA300 model number encodes the unit’s configuration: N4A identifies the condensing unit series, 342 indicates the 3.5-ton (approximately 42,000 BTU) capacity tier, AKA identifies the design revision, and 300 is the cabinet suffix. The n4a342aka300 tonnage is 3.5 tons; this is the largest common single-stage output class in the ICP N4A series at the 342 capacity tier. The N4A342AKN300 is an alternate revision designation within the same 3.5-ton N4A342 output class; many components are interchangeable between the AKA and AKN revisions, but confirm part numbers for control boards and wiring harnesses against the N4A342AKA300 specific listing before ordering from the AKN designation. The N4A342AKA300 manual documents refrigerant charge specification and electrical data. For diagnostic guidance, visit the ICP air conditioner troubleshooting section.
N4A342AKA300 Component Failures at the 3.5-Ton Output Class
N4A342AKA300 Capacitor and 3.5-Ton Compressor Startup Stress
The N4A342AKA300 capacitor is a dual-run unit serving the 3.5-ton compressor and condenser fan motor. At 3.5-ton output, the compressor draws higher locked-rotor amperage during startup than 2-ton or 3-ton units; a degraded capacitor produces a proportionally larger current overload per startup cycle. Annual microfarad testing before cooling season is essential; replace the capacitor when either section reads more than five percent below the rated value. Browse ICP central air conditioner capacitor parts.
ICP N4A342AKA300 Contactor and 3.5-Ton Switching Load
The contactor on the ICP N4A342AKA300 switches line voltage to the 3.5-ton compressor and condenser fan motor. At 3.5-ton output the contactor handles higher switching loads than 2-ton or 3-ton configurations, accelerating contact face erosion. Inspect the contact faces at each annual service; replace the N4A342AKA300 contactor when any pitting or erosion is visible, or proactively every four to five years in warm climates. Find compatible options at the ICP air conditioner contactor page.
N4A342AKA300 Fan Motor 3.5-Ton Output Class and Bearing Inspection
The N4A342AKA300 fan motor is sized for the 3.5-ton condenser coil’s airflow requirement. Bearing wear reduces operating RPM and coil airflow; replace the motor at the first sign of bearing noise. Confirm the 342 output class designation when ordering; motors from smaller N4A configurations are not interchangeable with the 3.5-ton motor. Browse ICP central air conditioner fan motor parts.
N4A342AKA300 Fan Blade Annual Inspection and 3.5-Ton Airflow Specification
The N4A342AKA300 fan blade is pitched for the 3.5-ton coil airflow requirement. Inspect the blade annually for physical damage and replace alongside the motor when damage is found. Confirm the blade diameter, pitch, and hub bore from the N4A342AKA300 parts list before ordering. Browse ICP central air conditioner fan blade parts.

ICP N4A342AKA300 Central Air Conditioner Parts FAQ
What is the N4A342AKA300 tonnage?
The n4a342aka300 tonnage is 3.5 tons (approximately 42,000 BTU). The 342 capacity tier in the model number identifies the 3.5-ton output class. Fan motors and blades must be specified for the 342 (3.5-ton) output class and are not interchangeable with N4A components from other capacity tiers in the same series.
Are N4A342AKA300 and N4A342AKN300 parts interchangeable?
Most N4A342AKA300 parts including the run capacitor, contactor, fan motor, and fan blade are interchangeable with the N4A342AKN300 within the same 3.5-ton N4A342 output class. Control boards and wiring harnesses may carry revision-specific part numbers; confirm the AKA revision is covered in the specific listing before ordering these components from the AKN designation.
What ICP brand parts are interchangeable with the N4A342AKA300?
Heil, Tempstar, WeatherKing, and Arcoaire are ICP brand channels sharing the same manufacturing platform. Parts for the N4A342AKA300 under any of these designations at the same 3.5-ton configuration are identical and interchangeable with no modification required.
Why does my N4A342AKA300 cool in mild weather but struggle at peak afternoon heat?
A unit that satisfies the thermostat at moderate temperatures but fails at peak afternoon temperatures has reduced heat rejection capacity typically caused by a degraded N4A342AKA300 capacitor reducing compressor and fan motor efficiency, an eroded contactor dropping supply voltage to the compressor, or condenser coil debris restriction. Test these three components in order before considering refrigerant charge as the cause.
