622686 – ECM BLOWER MOTOR (NORTEK, PWM, PROPRIETARY HARNESS)

If your indoor unit runs but produces weak or no airflow, the blower motor may need replacement. This Nortek-specific ECM has a proprietary wiring harness — NOT a universal motor. Verify your part number before purchasing.

Specs: 1/2 HP, 1050 RPM, 208-230V, 48-frame, ECM variable speed, PWM control, proprietary Nortek harness

Replaces: 622686, 622686R, E7EM-015H2

Fits: Nortek air handlers (includes Frigidaire, Gibson, Nordyne, Westinghouse brands using Nortek components)

Fits these models

• Direct replacement for Nortek / Intertherm / Maytag / Frigidaire ECM blower motors with proprietary PWM harness
• Common applications: Nortek-platform 90%+ AFUE gas furnaces and air handlers
• Does NOT cross over to GE/Genteq universal ECM motors — Nortek uses a proprietary connector and signal protocol

What's the difference between 5860 / 2.0 / 2.3 / EON?

These are GE/Genteq ECM motor generations. 2.0 = first-gen variable speed (1990s-2000s); 2.3 = newer, more reliable; EON = newest tier with built-in diagnostics. They share the 16-pin harness and PWM control protocol — the 5860 universal kit covers all three.

Will this fit my Trane, Carrier, or Goodman variable-speed furnace?

If your existing motor is a GE/Genteq 2.0, 2.3, or EON with a 16-pin connector and PWM control from the board — yes. Nortek/Intertherm proprietary harnesses do NOT cross over. Bring the old motor in if you're unsure.

How do I program the dip switches?

Match the new motor's CFM/torque settings to your tonnage and air handler model. The harness label inside the motor has the dip-switch chart. If yours is missing or faded, look up your air handler's installation manual.

Will an ECM motor lower my power bill?

True variable-speed ECM (this one) runs at lower watts during long, low-demand cycles — typically 25-40% less than a comparable PSC. Best savings come from running fan-only or first-stage cooling for longer, gentler cycles.
