Outdoor GFI keeps failing(not tripping)

av8rOctober 3, 2011

I have an outdoor gfi receptacle for outdoor low voltage submersable lights for a fountain. It was installed initially about 6 years ago and has been replaced about 5 times. I have a code keeper cover so I can leave the transformer plugged in. It typically trips a few times over many months(although not initially) and then eventually won't reset at all. I replace it and the whole process starts over again. There is no evidence of water or moisture inside the box and this last time I replaced it with an "outdoor weather resistant" gfi but still got the same results. Any suggestions? Is my transformer causing the gfis to fail?

Thank you for reporting this comment. Undo

Most likely just exposure and condensation.

GFCI devices rely on very small currents to sense the larger current imbalance between the hot and neutral.

A little dust and then some condensation upsets their operation.

The dust and moisture are inside the GFCI device and are not visible without taking it apart (and destroying it).
