I own a Rain Bird system and the main controls are located in the garage. At this time of the year... the temps get very high in the garage... pushing 100 degrees at times. What I've been noticing a few times... (last year during July/August) the controls are BLANK. My guess is the power (transformer) supply is over heating? Causing this to happen. One time... the controls went BLANK while the system was on (active) and it kept on watering my lawn for 3 hours straight... Nice water bill... yep I know. I was told that when the system loses power... it should automatically shut down all zones.

My question is... if it is the power supply... and the odd HOT garage temps causing this... what should I do? I tried to call Rain Bird directly... but customer service isn't accepting calls... apparently to the high call volume?

Just wondering if you or any of your friends ever had this happen to them?
