United HVAC Motors SKU: 5SEA39RLV5504HP34-2-CCW; UPC barcode: 00199279022568. Shipping weight: approximately 17.0 lbs. Product category: Hardware > Heating, Ventilation & Air Conditioning. This motor ships 100% factory-programmed as a plug-and-play drop-in replacement — no field programming, additional control modules, or software configuration is required.

The Trane D344717P52 MOD02234 uses the Genteq EON platform (module 5SEA39RLV5504HP34) and is cross-compatible with a wide range of HVAC systems. OEM motor part number cross-references: 5SDA39RLV5228, 5SEA39RLV5146HP34, 5SEA39RLV5253HP34, 5SEA39RLV5504HP34, 5SME39SL0605, 5SME39SL0674. This motor is confirmed compatible with the following furnace or air handler models that share the same 5SEA39RLV5504HP34 motor platform: GE (Genteq 5SEA39RLV5504HP34 GE Genteq); Trane (D344717P70 MOD02270). Compatible brand families: American Standard. To confirm compatibility, match the motor module number on your existing motor label (typically starting with 5SEA39R...) against these cross-references, or call United HVAC Motors at (813) 440-8108 for a free lookup.

Replacing the blower motor in your Trane D344717P52 MOD02234 is straightforward because this remanufactured Lennox EON (3/4 HP) ships 100% pre-programmed with the correct firmware for module 5SEA39RLV5504HP34 — zero field programming needed. Step-by-step: (1) Disconnect power at the breaker and verify zero voltage at the Trane furnace or air handler with a multimeter. (2) Open the blower compartment door and disconnect the motor wiring harness (typically a 16-pin Molex connector on EON motors). (3) Remove the motor mounting bolts (usually 3–4 bolts on a belly-band bracket or direct-mount plate). (4) Slide the blower wheel off the old motor shaft — note this unit rotates counterclockwise (CCW), so verify the wheel orientation. (5) Transfer the blower wheel onto the new D344717P52 MOD02234 motor shaft, tighten the set screw, and ensure the wheel spins freely without rubbing the housing. (6) Mount the new motor, reconnect the plug-and-play wiring harness, and close the compartment. (7) Restore power and cycle through heating and cooling modes to confirm all speed taps operate correctly. Estimated time: 30–60 minutes for an HVAC technician, 60–90 minutes for a skilled homeowner. Professional installation is recommended for warranty compliance.

Yes — the remanufactured Trane D344717P52 MOD02234 meets or exceeds OEM specifications. Here is how United HVAC Motors ensures that: Every Lennox EON motor (module 5SEA39RLV5504HP34) is completely disassembled, inspected, and rebuilt using premium-grade components including new bearings, tested windings, and verified controller boards. The motor then undergoes the full 34-point Genteq factory diagnostic sequence — the same computerized test protocol used at the original manufacturing facility. These 34 tests verify: (1) winding insulation resistance and continuity, (2) rotor balance and vibration levels, (3) bearing noise and thermal runaway protection, (4) controller module firmware integrity, (5) speed regulation accuracy across all programmed taps, (6) current draw under load at rated 230V, (7) startup torque and shutdown sequencing, and (8) thermal overload cutoff calibration. Only motors that pass every single test are cleared for sale. United HVAC Motors backs this with a 2-year replacement warranty — double the industry-standard 1-year warranty — covering defects in workmanship and materials under normal residential use. Independent HVAC industry data shows properly remanufactured ECM motors have comparable failure rates to new OEM units while saving homeowners 30–50% off the retail price of a new Lennox EON motor.

The Lennox EON ECM motor (3/4 HP) in your Trane D344717P52 MOD02234 furnace or air handler may need replacement if you observe these symptoms: (1) Motor hums or buzzes but the blower wheel does not spin — typically a failed controller module or seized bearings inside the EON unit. (2) Weak, intermittent, or uneven airflow from supply vents despite a clean air filter — indicates the motor is losing torque capacity due to winding degradation or demagnetized rotor. (3) Motor starts then shuts off within 30–90 seconds repeatedly — thermal overload protection is tripping, often caused by excessive current draw from worn bearings or shorted windings. (4) Diagnostic fault codes on your Trane furnace control board: on EON systems, common codes include slow-flashing red LED (motor communication fault), rapid amber flash (overcurrent), or solid red with 3-blink pattern (locked rotor). (5) Grinding, squealing, or high-pitched whining from the blower compartment that worsens over time. (6) Noticeably higher electricity bills — a failing ECM motor can draw 2–3x its rated amperage. Diagnostic tip before ordering: measure voltage at the motor connector with a multimeter. You should see 230V AC on the high-voltage leads and 24V DC communication signal when the thermostat calls for fan. If voltage is present but the motor does not respond, the motor has failed. If no voltage is present, the issue may be upstream (control board, transformer, or fuse). Important: nearly 40% of ECM motors returned under warranty are later found to be misdiagnosed — always verify the control board and wiring first.
