Richdel 476 Pri Station 4 Short Run: Voltage Test and Solenoid Check

Station 4 Runs Only 5 Minutes Despite 12‑Minute Setting

1. Disconnect the station 4 wire and the common wire from the controller.
2. Activate station 4 and measure voltage at the station 4 terminal (should be 24 VAC).
3. If voltage holds >5 min, the controller is fine—inspect the solenoid for cracks where wires enter; replace solenoid (~$8).
4. If voltage drops, the controller output is failing.
5. If solenoid and controller are good, the valve itself may be faulty—clean/rebuild.
