A sprinkler controller that shows a schedule but nothing runs — or one that runs at the wrong time, skips zones, or displays error codes — is one of the most frustrating irrigation problems in Calgary. This guide covers the most common controller issues and repair costs.
Controller Troubleshooting — Calgary Quick Diagnosis
| Problem | What to Check First | Likely Fix | Cost |
|---|---|---|---|
| Controller screen blank | Power supply, outlet, and transformer fuse | Replace transformer or check circuit breaker | $40-$120 |
| Program saved, no zones run | Rain sensor in bypass mode, program start AM vs PM | Disable rain sensor bypass; check start time AM/PM | Free (DIY) |
| Zone 1 runs but others do not | Individual zone terminals on controller board | Test each zone manually from controller | $60-$280 |
| Error: short circuit | Wiring fault — disconnect zones one at a time | Identify and repair shorted wire or solenoid | $80-$250 |
| Controller loses programming after power outage | Backup battery dead or missing | Replace 9V backup battery inside controller | $5-$10 (DIY) |

When to Replace vs Repair a Calgary Sprinkler Controller
Replace if: the controller is 10+ years old, shows recurring error codes, or lacks smart features. Repair if: the issue is a single zone failure, wiring problem, or minor component. A new Hunter Hydrawise or Rachio 3 controller installed by J.G. Irrigation runs $180-$550 and includes smart weather scheduling that reduces water bills by 30-50%.
