Compatibility
-
Nordyne / Intertherm single-speed air handlers and furnaces
-
Common in E4EB, B6, FM, and GMH series models
-
Requires matching 4–5 μF run-type capacitor (verify exact value per system)
Technician Notes
-
Verify rotation: confirm CCWLE by viewing shaft end; mounting orientation matters.
-
Match capacitor: use a 4–5 μF, 370 VAC run capacitor—undersized values reduce torque.
-
Inspect shaft play: radial and axial movement should be under 0.003 in to avoid vibration.
-
Clean blower wheel: remove dust and debris to prevent imbalance and noise.
-
Apply anti-seize on mounting bolts; torque to OEM specs (typically 18–22 in-lb).
-
After installation, measure full-load amps; acceptable range is 85–120% of nameplate.
-
Listen for unusual noise during first cycle; reseat wheel if necessary.
-
Photograph wiring harness before removal; match wire colors and connector positions.
