Why did the outside weatherproof outlets quit working?
This outlet is GFCI protected and is located in the weather proof cover on the outside of your home. In some cases the outlet is protected by the GFCI in the garage. Remember that if the inoperable outlet is up high, such as a Christmas eve outlet, there is often a light switch in the garage for them. The switch needs to be “on” in order for the outlet to work. Weatherproof outlets are not dedicated outlets; they are easily overloaded by outside appliances such as electric garden tools.
