Common Signs Your Stabilizer Is Faulty A Guide by A&E Dunamis
A voltage stabilizer is your home or business’s first line of defense against dangerous voltage fluctuations. But like every electrical device, stabilizers can develop faults over time. Ignoring these warning signs can lead to serious appliance damage and expensive repairs.
At A&E Dunamis, we want you to know the common signs your stabilizer is faulty so you can take quick action and protect your investments.
1. Unstable Output Voltage
If your stabilizer is no longer giving a steady output voltage, your appliances may still be at risk.
- Symptom: Lights flickering, TV screen distortion, fridge making unusual sounds.
- Cause: Faulty internal circuitry, damaged relays, or worn-out voltage control components.
2. Overheating
A stabilizer should get warm during operation, but excessive heat is a red flag.
- Symptom: Outer casing feels unusually hot, sometimes with a burning smell.
- Cause: Overloading, poor ventilation, or internal short circuits.
- Risk: Can lead to complete unit failure or even fire hazards.
3. Frequent Tripping
If your stabilizer keeps switching off or resetting itself:
- Symptom: Sudden loss of power to connected appliances.
- Cause: Overload protection activating too often, faulty sensors, or poor wiring.
- Solution: Reduce connected load and have it inspected immediately.
4. Unusual Noises
A healthy stabilizer operates quietly.
- Symptom: Loud humming, buzzing, or clicking sounds.
- Cause: Faulty transformer, damaged servo motor, or loose internal parts.
5. Delay Timer Not Working
Many A&E Dunamis stabilizers have a delay start function to protect appliances from sudden power surges.
- Symptom: Appliances start instantly instead of after the set delay.
- Cause: Defective delay circuit or damaged control board.
6. Physical Damage or Burn Marks
Never ignore visible signs of wear.
- Symptom: Cracks in the casing, burnt smell, melted plastic, or scorched
