How to Fix / Troubleshooting

Safety first: Unplug the machine and allow it to cool fully before working on it.

Restore airflow: Replace the filter bag if near full. Remove and inspect pre-motor and exhaust filters; replace if dirty. Clear any blockages in the hose, wand, and nozzle.
Check cooling vents: Inspect the body for dust build-up on cooling vents. Use a soft brush and vacuum to clean them.
Test run: After cleaning and reassembly, run the machine and monitor. If it still shuts off quickly, the motor may be overheating due to internal faults.
Professional service: Repeated thermal trips indicate a failing motor or incorrect current draw. Have a technician test and replace the motor if necessary.

Do not bypass or short the thermal protector; it is a critical safety device.
