  If all stations fail to turn on, there might be a few reasons: * The transformer might be defective or not properly connected. Check the connections and the outlet. If there's still no A/C power, replace the transformer. * The programming could be incorrect. Verify the Start Time and Watering Days settings. * The timer might be in OFF mode. Ensure the dial is turned to AUTO.

  If one or more stations aren't turning on, consider these potential causes: * A faulty solenoid may be the issue. If so, replace the solenoid. * There might be a broken or disconnected wire. Repair the wire and check all connections. * The flow control stem could be screwed down, shutting the valve off. Turn the flow control stem counter-clockwise to achieve the desired flow. * The programming might be incorrect. Ensure the station in question is set to water with a program.

  If stations are turning on when they shouldn't, it could be due to: * High water pressure. Consider installing a pressure reducer. * Multiple start times programmed. Reduce the number of start times for that program. * Stations set to water with both programs. Set the station duration to 0 for the program you don't want it watering with.
