A:Answer Thermal Protector has been designed into your cleaner to protect it from overheating. When the thermal protector activates the cleaner will stop running. If this happens proceed as follows:
1. Turn cleaner off and unplug it from the electrical outlet.
2. Empty the dirt cup.
3. Inspect the nozzle inlet, hose connector, hose, dirt cup inlet, pre-motor filters, and HEPA filters for any obstructions. Clear obstructions if present.
4. When cleaner is unplugged and motor cools off for 30 minutes, the thermal protector will deactivate and cleaning may continue.
