Can this be repaired or does it have to be replaced?

Generally I'd say that they would replace the entire unit. Even it was repairable (assume a chip went bad and could be replaced) the unit would still have to be taken out and put back in after repair, and you'd have "diagnostics" and labor for the fix on top of that. Might actually cost more to repair and take longer on top of it.
