What to do if my NuTone SFDB-DE power unit stops suddenly?
- DDarren BeltranAug 8, 2025
If your NuTone Vacuum Cleaner's power unit stops suddenly, there are several potential causes. First, the power unit overcurrent protector might have been activated; turn the unit off, check the overcurrent protector button on the left side of the unit (push to reset), and then turn the unit back on. Another possibility is that the thermoprotector has been activated; in this case, turn the unit off and wait 30 minutes for it to cool down before turning it back on. Also, check the house electrical panel for a blown fuse or tripped circuit breaker and replace the fuse or reset the breaker. Finally, a defective inlet or hose could be the cause, requiring replacement of the defective wall inlet or hose as needed.
