One set of christmas lights was plugged into the garage gji plate.
Christmas lights stopped working after rain. Customerreply replied 13 years ago. Last Sunday I put up about the same amount of lights in the same manner as I have for about 15 years. Examine the plastic closely on the side of this box and in between the prongs for a cover you can slide or pry open.
Consider using insulated fasteners to secure the lights in place. Outside Outlets Not Working After Rain Storm Hello i have recently moved into a new house and during a rain storm all of my Christmas lights shut off. You might try spraying some WD-40 into the ends of the extension cords and on the plug end of each light stringer.
Using the handy Light Keeper Pro I was able to quickly fix a lot of the lights on this lighted Christmas reindeer. Test the lights by plugging them in. Plug a little lamp into it to check.
It could be that moisture wet snow ice or rain has caused the issue. I have an outside porch light that loses power after a heavy rain as does the entry light fixture inside the house which shares the circuit. I would check all of your extension cords and connections.
A bulb has burnt out and has created a cascading outage. The circuit isnt carrying power. Open the fuse case.
Check the light again to see if any of the bulbs work. If the lights still dont work you can use the tools detector according to the manufacturers instructions to locate the problem area then replace the bulb here. Store your lights in a plastic storage container or bag and keep them free from moisture rain and humidity.
