Hi,
ICE is potential freeze condition warning. Should not relate to the pump issue.
Is your new motor same Amperage as old one?
Is the wet end(pump) on the new pump the same horse power as the one it replaced?
Lack of ventilation for the motor, or clogged motor vents.
Check for undersized wiring or poor electrical connections.
Check if your pump has a thermal overload, this safety mechanism will turn the motor off when it gets too hot. The pump should restart once it cools down.
Remove the intake plumbing and visually inspect the impeller, observe for impeller failure. Spin the impeller to see if it turns without impedance.

Before you inspect the pump turn of the power to avoid electrical shock!
