    A restaurant I maintain had not ran their system all year and the grass was really burning up due to no rain and 105+ temps every day. I talked to the manager and she said it was broke. I told her I would look at it, so she showed me where it was. I took the plug out of the wall, hit the reset button on the GFCI and wa-la!
    So the lesson of the day is controllers and GFCI's are not best friends!

    Anyone else had a easy fix like this?

    I don't have many GFI issues. Necessary evil of our electrical codes.

    check fuses
    check rain sensors
    check for band solenoids
    check breaker
    check wiring inside the clock
    test output voltage
    open up valve boxes and clean them out check wiring

    Mega lesson of the day. Never ever plug a clock into a GFI circuit.
    The electricians can give you power ahead of the GFI at any outlet.

    That right there is our #1 "warranty" call. We NEVER plug straight into a GFI, but code here calls for garage and exterior recepts to be GFI-protected. They always wire them on one circuit, so we always get the "It says POWER OFF" call. Depending on their location, my mood, and/or my bank balance, I may tell them how to "fix" it, or I may show up and collect for a service call.

    I wash the windows before we take the Airstream out.

    I think this GFCI was code because it is in the hot water closet. No other outlet available and not sure if it could be different.

    This was one of the old Dial type rain bird controllers. No digital display or anything so it appeared to be "broke"

    I don't give a rat where anyone ties in, get in front of the GFI.

    Many installations are using wallwarts and indoor controllers, in garages and basements, so there is no non-gfi option.
