Irritrol KwikDial Two Solenoids Per Station Fail After 3 Years: Voltage Drop Under Load

Stations 2 and 3 Each Drive Two Solenoids; Work Individually, Fail Combined

After 3 years, combined solenoids don't actuate. Single works.

Cause

Insufficient voltage at solenoids when two wired in parallel (wire gauge too small for distance, or connections degraded).

Checks

  • Verify both hot wires from controller connect to both solenoids (parallel).
  • Check wire gauge — may need larger wire for distance.
  • Solenoids likely OK since they work singly.
