Richdel Timer Switches Malfunctioning: Replace Controller

Richdel controller switches move on their own or won't stay in position; tape needed to hold them.

Verdict

Controller is 10+ years old. Mechanical switch failure is not repairable. Replace with an Irritrol Rain-Dial (6, 9, or 12 station, $100–130). Installation labor $50–75, or DIY.
