I have a circuit in the house we just moves into that controls the outside
lights, light over the front door, light on post, light over garage, and an
outdoor GFCI receptacle that low voltage lights along the walkway are plug
In anticipation of winter I went and bought a timer switch so these lights
would be on when I came home. After I put the switch in everything worked
except for the GFCI outlet. There is an orange light on it and pushing the
reset does nothing. I have to believe that the installation of the switch
had something to do with this as it all worked fine before.
What could I have done wrong? House is 1970's vintage with old/new electri
cal in it.
What brand/model is the timer switch and the GFCI?
The GFCI manual would tell you the meaning of the light. Or use a multi
meter to measure the voltage going into the GFCI and to make sure the
polarity is correct.
To prove the new timer switch is the cause, remove it and see. Some
timers contain SS components which can cause problem like that. Is the
switch before the GFCI or after? That makes difference too. All our
outside lights are dusk to dawn light sensor controlled.
Assuming that this GFCI receptacle is on the load side of this timer,
like all the other things mentioned. As gfretwell said, the power must
be on when you attempt to reset a newer GFCI receptacle. You could have
reversed the polarity to the GFCI receptacle, when installing the timer,
or it could have just gone bad.
Some GFCI outlets can provide protection for additional non-GFCI
outlets. The outlet has a "Line" end where power from your breaker box
is connected. If needed, additional outlets would be connected to the
"Load" end of the GFCI outlet.
One reason your GFCI outlet will not reset, might be that you connected
power from your breaker box to the "Load" end of the outlet.
As others mentioned, power must be present for a GFCI to reset.
