## Blower Motor FAQs
**Q: How do I know if my blower motor is failing?**
A: Warning signs include:
- Motor won't start or hums
- Squealing or grinding noises
- Overheating/burning smell
- Intermittent operation
- Weak airflow from vents
- Motor runs continuously
- Tripped breaker or blown fuse
**Q: Can I replace a belt drive motor with direct drive?**
A: Maybe. Requires new blower wheel and housing modifications. Usually better to replace with same type.
**Q: What's better - PSC or ECM motor?**
A: ECM motors are more efficient (saves $100+/year on electricity), quieter, and provide better comfort. PSC motors are less expensive upfront.
**Q: Can I install an ECM motor in my old furnace?**
A: Often yes. Many ECM motors can retrofit into PSC applications. May need compatible control board.
**Q: Do I need to replace the capacitor with the motor?**
A: Yes, recommended. Old capacitors can damage new motors. Always install fresh capacitor.
**Q: What if my motor has 5 wires but the new one has 4?**
A: Universal motors often have different wiring. Use wiring diagram provided with new motor. We can help!
## Installation Guidelines
**Safety First:**
1. Turn off all power (breaker and furnace switch)
2. Verify power is off with voltage tester
3. Take photos of all wire connections
4. Label wires if needed
5. Note wire colors and terminal positions
**Direct Drive Motor Installation:**
1. Remove blower assembly from furnace
2. Remove old motor mounting screws
3. Slide blower wheel off old motor shaft
4. Install blower wheel on new motor (same depth!)
5. Mount new motor in blower housing
6. Connect wires per diagram
7. Install new capacitor if applicable
8. Test motor rotation direction before reassembly
**Belt Drive Motor Installation:**
1. Loosen motor mounting bolts
2. Remove belt from pulleys
3. Disconnect wires (photos first!)
4. Remove old motor
5. Mount new motor in same position
6. Connect wires per diagram
7. Install and tension belt properly
8. Test and adjust as needed
**Post-Installation:**
- Verify proper rotation
- Check for vibration or binding
- Measure amp draw
- Test all speeds if multi-speed
- Ensure adequate airflow from vents
- Listen for unusual noises
## Troubleshooting Common Issues
**Motor Hums But Won't Start:**
- Bad capacitor (most common)
- Seized bearings
- Bad start winding
- Incorrect wiring
**Motor Runs Backwards:**
- Reversed wiring connections
- Swap appropriate wires per diagram
**Motor Overheats:**
- Dirty blower wheel (causes motor strain)
- Restricted airflow (dirty filter)
- Wrong voltage or speed
- Failed capacitor
- Overloaded motor (undersized)
**Intermittent Operation:**
- Loose wire connections
- Faulty control board
- Thermal overload tripping
- Bad capacitor
## Blower Motor Maintenance
Extend motor life with regular maintenance:
- Keep blower wheel clean
- Replace air filters monthly
- Lubricate motor bearings annually (if applicable)
- Check and tighten all connections
- Verify proper belt tension (belt drive)
- Test capacitor annually
- Keep area around furnace clean
## When to Upgrade to ECM
Consider upgrading from PSC to ECM motor if:
