Possible Causes
Loose battery connection, Weak battery cells, Overheating motor, Faulty thermal cutoff switch
How to Fix / Troubleshooting
Safety first: Remove the battery before inspecting connections.
Steps to try:
- Check battery latch: Ensure the battery clicks firmly into place. If the latch is worn, the battery may lose contact during use.
- Test while holding battery: Run the vacuum while gently pressing the battery into the housing. If it stays on longer, the contacts or latch are the issue.
- Clean contacts: Wipe the battery and vacuum contacts with a dry cloth to remove dust or oxidation.
- Allow cool-down: If the body feels warm, let it cool for 30 minutes and then test again. Repeated quick shutoffs may indicate a failing motor or thermal switch.
- Replace suspect part: If a new battery does not resolve the issue, replace the motor assembly or main body module.
