Does the HUSQVARNA QC500 charger need to display indicator lights and run a fan when plugged in?

Question

Accepted Answer

When you plug the HUSQVARNA QC500 charger into an electrical outlet, it is normal for the charge LED to blink once. This blinking indicates that the charger is powered on and ready to operate. This is the standard behavior of the QC500 when powered on.

Once you connect the HUSQVARNA battery to the charger, the charge LED lights up continuously to indicate that the battery is charging. During normal charging, this LED remains lit. When the battery is fully charged (after about 1 hour), you can press the battery indicator button to check its charge status.

However, the fan should not turn on simply by plugging in the charger. If you notice that the fan is running when plugging in or during the charger’s standby mode, this indicates abnormal operation or an internal issue.

If the fan is running abnormally, first check that the charger is operating under the recommended conditions: the ambient temperature should be between 5°C and 40°C. An environment that is too hot may trigger the fan or cause failures. Also, visually inspect the charger and its cable for any visible damage, and clean it with a dry cloth if necessary.

If the problem persists despite following the usage conditions, the charger likely has an internal malfunction and should be checked or replaced. Contact your HUSQVARNA dealer to have the QC500 inspected.
