Timer & Controller Repair in Brownsville, TX
The controller, often called the timer, is the brain of your sprinkler system. When it fails or loses its settings, zones run at the wrong time, run too long or do not run at all. We troubleshoot the controller, the wiring and the valves, then set a schedule that fits the season.
Signs you need timer or controller repair
- A zone will not turn on, or will not shut off
- The display is blank, frozen or shows an error
- The system runs at times you did not program
- Settings reset after a power outage or storm
- The rain sensor never seems to stop a cycle
- You want to switch to a Wi-Fi smart controller you can run from your phone
What we do
Controller problems are often wiring or valve problems in disguise. We check the whole chain.
- 1
Look
We review the current program with you and run each zone from the controller.
- 2
Diagnose
We test the controller's output, the field wiring and the solenoid on each valve to find where the signal stops.
- 3
Explain the price
We tell you whether a repair, a reset or a new controller makes the most sense, and what each one costs.
- 4
Repair and test
We fix the wiring or valve, repair or replace the controller, program a seasonal schedule and run every zone to confirm it.
Smart timer installation
A Wi-Fi smart controller connects to your home network and adjusts watering based on local weather. You can pause it from your phone when rain is coming, check that every zone ran, and make changes without standing in the garage.
We install smart controllers from several makers and pick one based on your zone count, your Wi-Fi signal where the controller hangs and how hands-on you want to be. We set it up, connect it to the valves and walk you through the app.
A smart controller is not required for a healthy lawn. A standard timer set correctly for the season does the job too. We will tell you honestly which fits your yard.
Many older controllers have more than one program, often labeled A, B and C, and leftover start times in a program nobody uses are a common reason a system runs at odd hours. Clearing those out is one of the first things we check.
If the controller is fine but a valve still will not open, the problem is usually in the field. We trace the wire from the controller terminal to the valve, test the solenoid and repair the splice or the part that failed.
Outdoor controllers need a cabinet that keeps out rain, dust and insects. Ants and wasps like the warmth inside a controller box in the Valley, and their nests can short out the terminals. If yours is mounted outside, we check the cabinet, seal and wiring entry while we are there. If the controller hangs in a garage that bakes in summer, we may suggest a cooler spot when replacing it.
Quick checks before you call
- Check that the controller has power and the display shows the correct date and time.
- Look at the rain sensor switch or setting. If it is set to active and the sensor is stuck, nothing will run.
- Write down which zones misbehave and when. A short note helps us find the cause faster.
Controllers in the Brownsville climate
Heat and humidity are hard on electronics mounted outdoors or in a hot garage. Corroded terminals and failing transformers show up often in older controllers here. Power flickers during summer storms can scramble programs, so a controller with battery or memory backup is worth having.
Brownsville's watering needs also shift through the year. Summer heat calls for more water, while cooler months need far less, even though the lawn stays green. The Brownsville Public Utilities Board can put water-use limits in place during drought, so we set schedules that respect whatever stage is in effect and show you how to adjust when it changes.

Timer & Controller Repair: common questions
Why will one zone not turn on?
The most common causes are a broken wire, a failed solenoid on the valve or a stuck valve. Less often, the controller itself has a dead output. We test each piece to find the real cause.
Why does my system keep running after the cycle should end?
A valve stuck open will keep that zone watering even with the controller off. Debris in the valve or a torn diaphragm is usually to blame.
What is a rain sensor?
A rain sensor is a small device mounted on a fence or roof edge. It tells the controller to skip watering after enough rain falls. Many stop working over time, and a quick test shows whether yours still does.
Do I need a smart controller?
No. It is a convenience that can save water by reacting to weather. A standard timer that is programmed well for the season also works.
Can you program my timer to follow BPUB drought rules?
Yes. Tell us your address and we will set the schedule to match the drought stage in effect and show you how to change it later.
