Sprinkler Controller & Timer Repair in Winter Garden, FL
When the system runs at 3am, skips days it should water, or does nothing at all, the controller is where diagnosis starts. Central Florida is hard on controllers — lightning season, power blinks, and garage heat all take a toll — and half of "broken controller" calls turn out to be programming tangles around the local watering rules.
Repair vs. reprogram
The split is real: dead displays, zones that never fire from any program, and post-storm failures are hardware — transformers, fuses, lightning-cooked boards, or the controller itself. Wrong-time watering, skipped days, double-running zones, and mystery schedules are programming — often three overlapping programs left by three previous owners. The visit sorts which one you have in minutes, because replacing a controller to fix a programming tangle is the expensive way to not fix it.
What storm season does
Lightning does not need a direct hit; surges down the power line or the valve wires cook solenoid outputs one zone at a time. The pattern — zones dying one by one over a summer — is the signature. Repair ranges from a fuse to a new controller, and a surge-protected outlet is cheap insurance worth mentioning while the panel is open.
Programming around the watering rules
Every controller in West Orange County should be programmed around the local day-of-week watering restrictions — wrong-day watering is the most common code-enforcement letter a lawn can earn. Reprogramming to the current allowed days, with seasonal run times and a sane start hour, is part of any controller visit, not an extra.
Rain sensors and smart upgrades
A working rain sensor is required equipment for automatic systems in Florida and pays for itself in skipped cycles; a failed one quietly waters through thunderstorms. Sensor repair and replacement is routine. Smart controllers — weather-based scheduling, phone control — are a worthwhile upgrade conversation when an old unit dies, presented as the option it is rather than the upsell it is not.
System watering at random hours?
Bring the symptom, not a diagnosis — 'it ran twice last night' is enough. Controller visits usually wrap up in the same visit, reprogrammed around your watering days.
Frequently asked questions
My controller display is blank. Dead unit?
Maybe just power — outlet, transformer, fuse, or a tripped GFCI in the garage. That chain gets checked before any replacement talk; blank-display calls split about evenly between power and unit.
Is wrong-day watering really enforced?
Yes — Central Florida districts and counties enforce day-of-week restrictions, and wrong-day watering is a common violation letter. Reprogramming to your allowed days is part of the visit.
My rain sensor never seems to do anything. Broken?
Possibly — sensors fail stuck-dry (waters through storms) or stuck-wet (never waters). A quick test tells, and replacement is inexpensive relative to the water it manages.
