  Heather Hester DDSAug 5, 2025
  If the Nidec Engine motor isn't spinning or is running abnormally, here are a few things to check: * Make sure the thermostat is calling for activity. * Check the circuit breaker to make sure it hasn't tripped or been accidentally shut off. * Ensure the wiring harnesses are securely connected to the control connectors. * Look for any shorts or detached wiring. * Inspect the control for any broken or loose connectors, moisture, excessive dirt, or other damage.

  If the Nidec Engine motor rattles or makes excessive noise, inspect the following: 1. Motor and blower for accumulated dirt, internal debris, or other signs of damage. 2. Blower fan for bent or missing blades, misaligned shaft, or unsecured mounting to the shaft. 3. Blower housing for cracks, dents, or corrosion. 4. Blower housing for secure mounting to the system chassis. 5. Shaft, and verify that the motor shaft spins freely without effort or assisted means in both directions.
