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?
