Possible Causes

Shorted or open door lock coil, Damaged lock wiring, Control board lock driver failure, Incorrect replacement lock installed

Safety first: Disconnect power before servicing.

Verify correct part: Ensure any recently replaced door lock assembly matches the original part number.
Inspect wiring: Check the harness from the lock to the control for shorts, burns, or breaks.
Test lock coils: Measure resistance of the lock coils with a multimeter. Replace the lock if readings are out of spec.
Control board: If the lock and wiring are good, the control board's lock driver may be damaged and require replacement.
