Irritrol Rain Dial RD1200 Button Failures – Panel Replacement

Irritrol RD1200: Semi‑Auto, Manual, and +/- Buttons Not Working

An Irritrol Rain Dial RD1200 runs on automatic, but semi‑auto start, manual start, and +/- buttons (held down) fail. All buttons worked for years; other functions are fine.

Diagnosis & Fix

Remove battery, disconnect power for one minute, restore power without battery. Test buttons. If they still fail, the button contacts are worn. Replace the front panel or the entire controller.
