The Fix-It Playbook — Sprinkler Controller Flowchart | Free 1-Page PDF | 2026 Edition

Blank display, wrong schedule, or a dead zone? Most controller fixes cost nothing.

Two questions sort it. Is the same problem on every zone — if it's one zone, the controller is fine and it's that zone's wire or valve. Then hit Manual Run: a zone that comes on means a programming problem, nothing at all means no power, three steps each.

The sheet also carries the transformer multimeter quick-read (24–28 volts healthy, near zero means replace), and a plain line on when to stop and call a pro.

One page. Print it or keep it on your phone. Free instant PDF download, yours to keep.

If the tree sends you deeper: How to Program & Fix Your Sprinkler Controller ($6) adds the zone-by-zone run-time chart, the single-dead-zone walkthrough, and the habits that keep it from happening again. All four irrigation guides come together as the Irrigation Repair Kit ($11), and all 24 year-round guides are in the Core Library ($49).
