It should do! Mallard Ducks lay a few eggs every year around 1-7 or even 8! Just take your duck to the vet if it lays one , unhealthy egg!
It is unlikely you can salvage the hatch once the incubator fails unless you can bring the eggs back up to ideal temperature quickly. A cooling down of more than 6 hours will severely affect the hatch rate. You could supplement the temperature loss with heat lamps temporarily but replacement of the incubator or the thermo-wafer is recommended.
