Possible Causes

Failed clock circuit on control board, power interruptions without battery backup, incorrect time-of-day setting, defective internal capacitor

How to Fix / Troubleshooting

Safety first: Disconnect power before removing the control cover.

  • Set correct time: Re-enter the correct time-of-day and regeneration time. Monitor for 24 hours to see if the clock drifts or resets.
  • Check power stability: Ensure the outlet is not controlled by a switch or subject to frequent outages. Use a surge protector if power quality is poor.
  • Inspect control board: Look for corrosion or damage around the clock circuitry. If the clock loses time even with stable power, the board is failing.
  • Replace control board: Install a new Fleck SXT/XTR control board if the clock cannot maintain accurate time.
