Repair if: The clock motor hums but turns, the metal casing is intact, and you only need 4 stations. Replacement gears and transformers are available on eBay.
Upgrade if: You have lost the station pin wheel, the plastic is brittle, or you want Wi-Fi control (look at the Rain Bird ESP-TM2 or ST8-WiFi).
| Problem | Likely Solution | |---------|----------------| | Timer won’t turn on | Check power cord/outlet. Ensure transformer is plugged in. | | No watering at set time | Dial must be in AUTO. Check start time pins are pushed in. | | Watering runs too long/short | Recheck SET WATERING TIME dials. | | Watering happens on wrong days | Adjust skipper pins in SET DAYS BETWEEN. | | Manual mode runs briefly then stops | Turn dial to AUTO after manual start; the timer may be mid-cycle. |
