Symptoms
- Motor doesn't spin when trigger is pressed
- Motor spins but little or no air comes out
- Device stops after a few seconds of use
Likely causes
- CommonBattery not chargedThese devices often need a full charge before first use and can drain quickly with heavy use.
- CommonNozzle or intake blocked with debrisDust pulled in from cleaning tasks can clog the intake filter or nozzle.
- PossibleOverheat protection triggeredContinuous heavy use can trigger a thermal shutoff to protect the motor.
- Less commonTrigger switch faultA worn or dirty trigger switch may not engage the motor reliably.
What to do
- Charge the device fully before testing, especially if it's new.
- Check and clean the intake filter or screen for dust buildup.
- Inspect the nozzle for any visible blockage and clear it.
- Let the device cool down for several minutes if it just shut off after heavy use.
- Use in shorter bursts rather than continuous long runs if overheating is an issue.
- Try wiggling or cleaning around the trigger switch if it feels inconsistent.
- Contact the manufacturer if the motor won't run at all on a full charge.
