Unpleasant Smells
A strange or fishy odor is one of the first warning signs of a faulty electrical appliance, and it could indicate that some components within the device are overheating. This is due to the fact that most electrical wires are made of heat-resistant chemicals that, when burned, begin to smell like fish.
If you smell something strange coming from an electrical outlet, unplug everything in the outlet right away. Don't use it again until an electrician has thoroughly inspected it. You should check the terms and conditions of your home warranty to see if electrical issues are covered. If you're in the market for a new policy, look for one that addresses these concerns.
