The 230VAC contactor has momentarily dropped out. This could be due to wiring issues, voltage glitches, or a damaged inverter drive. The system will revert to a 5-minute cycle delay.
Click steps to track your progress.
Verify the contactor harness from the ODU control for loose connections, stripped wires, shorts, and proper connection at control board and contactor.
If voltage glitches or low line voltages are persistent, contact your power provider for assistance.
If wiring checks out, the inverter drive may be damaged and require replacement.
