Voltage fluctuations are small changes in electric power that come and go in many homes.
Though they don’t look serious, but over time they slowly damage appliances in ways people don’t notice.
When voltage is too high, it pushes extra current into the appliance. Parts inside like motors, compressors, and circuits begin to heat up more than normal. This extra heat weakens them little by little until they fail.
When voltage is too low, appliances struggle to work properly. The fridge tries harder to cool, and a fan may turn slowly but it will still draw power. This strain also reduces their lifespan.
The damage is not always immediate. It builds up slowly over months or years. That is why many people think an appliance “just stopped working,” but the real cause is long-term stress from unstable power.
Some appliances are more sensitive than others, especially fridges, TVs, and washing machines. Even small fluctuations can affect their performance.
Using a stabilizer or surge protector can help reduce this risk. Also, unplugging appliances during unstable power supply is a simple way to protect them.
In the end, steady power keeps appliances healthier and helps them last much longer in any home.
