Irritrol RD-900 Blinking Display: Replace Panel or Repair

Blinking display on RD-900 after manual zone attempt = known age-related panel failure. One component on the board fails.

Options

• Local irrigation shop may repair panel.
• Buy new panel (snaps in) — cheaper than full controller.
• Internal fuse exists but requires panel hinge-out; usually not the cause.

Reset Not Effective

This isn't a software glitch — it's hardware degradation.
