Questions and answers
I work at a school that has an SPL 4213. The fan buzzes when we flip the switch but the blades won't spin unless we assist them. I called a few days ago and was told to blow the motor out. Tried that but still the same. Any other suggestions?
If the HEAT BUSTER SPL 4213 fan buzzes but does not spin, follow these troubleshooting steps:
1. Check for power issues:
- Ensure the power cord is plugged in.
- Check the fuse or circuit breaker.
2. Inspect the switch:
- A faulty switch may prevent the fan from operating. Replace the switch if needed.
3. Check the motor:
- A defective motor can cause buzzing without spinning. Replace the motor if it is not functioning.
These steps address common causes such as faulty switches, motor issues, or lack of power.
