Irrigation Controller Not Running a Program

A controller that does not run its schedule may still have power and a working manual test. Check schedule state, clock, seasonal settings, sensors, and station outputs in that order.

Symptoms to compare

• Manual station tests work but automatic start never occurs.
• The display time, day, or program is incorrect.
• A sensor icon, rain delay, or bypass setting suppresses watering.

Free diagnostic checks

1. Confirm clock, day, start time, program, run times, and allowed days.
2. Check seasonal adjustment, rain delay, off state, and sensor indicators.
3. Run the program manually and note whether it stops at one station.

What the result usually means

• A disabled program or incorrect clock prevents a start.
• A sensor or rain delay suppresses automatic cycles.
• A station output or field-wire fault affects one zone in the sequence.

Free diagnosis boundary. Do not open the controller primary-voltage compartment unless qualified; use low-voltage controls for routine diagnosis. Use the matching Repair Guide for the protected repair procedure, parts list, testing, and verification.
