Cleanliness, proper ventilation and cooling, avoiding moisture to seep through the equipment, would keep it work for you longer. Make sure that water or liquid should never get inside the parts of the machinery that is strictly prohibited; it prevents accidents and protects the home appliance.
Keeping a vigil eye on the moving parts of the electrical and electronic devices periodically, so that dust particles won’t be deposited around the moving parts and jam its movability. Approximately 95 per cent of maximum damages are found out during the visual inspection process. Wires, plugs, sockets and connectors are observed carefully and the worn out parts need instant replacement.Blown out fuses, require immediate replacement before you start using the electronic or electrical unit again.
For proper maintenance make sure, never to plug in outlets than are meant for lesser power than the equipment is designed to be. Plugging in high voltage requiring outlets with lower voltage sockets may burn the machinery and cause fire hazards. Have a proper neutral system that would dissipate the overloading electricity and protect all the electronics and electrical instruments inside the house. The commercial electronics equipment run the same way and electronics suppliers insist on following the safety measures, after installation of the products.
