Outlets can stop working for many reasons. One common cause is tripped circuit breakers, which cut off power to the outlet. Faulty wiring within the outlet or in the electrical system can also lead to non-functioning outlets. Loose connections, damaged outlets, or short circuits can also disrupt the flow of electricity. Outlet failure can also occur due to overloading the circuit or using incompatible devices. In some cases, there may be internal damage caused by electrical surges, moisture exposure, or aging components.
