It is not typical for a hairdryer to suddenly go dead silent for a few minutes and then spark, scream loudly, and blow at a significantly higher speed. Such behavior would indicate a malfunction or a serious electrical issue with the hairdryer, which could pose a safety hazard.
If you encounter this kind of situation with a hairdryer or any electrical device, it is important to immediately unplug it from the power source to prevent further damage or potential harm. Here are a few possible explanations for the described scenario:
Internal Fault or Short Circuit: The sudden silence could be due to an internal fault or short circuit that caused the hairdryer to stop working temporarily. The subsequent sparking, loud noise, and increased speed may indicate a sudden release of built-up electrical energy or a component failure within the hairdryer.
Overheating or Overload: Hairdryers have safety features to prevent overheating or overloading, such as thermal fuses. However, if these fail or are bypassed, the hairdryer's motor could overheat, resulting in unusual behavior such as sparking, loud noises, and increased speed.
Wiring or Connection Issues: Faulty wiring or loose connections within the hairdryer can lead to unpredictable behavior. Loose wires or faulty connections could cause intermittent loss of power, followed by sudden power surges, sparking, and loud noises.
Regardless of the cause, it is crucial to stop using the hairdryer immediately and have it inspected or repaired by a qualified professional. Continuing to use a malfunctioning electrical device can be dangerous and may result in electrical shocks, fires, or further damage to the appliance.
