At Monogram’s largest dual-fuel size, the ZDP48N6DDSS still isolates each oven cavity’s heating elements and sensors from the other, so a single-cavity problem doesn’t require replacing the shared control board unless that board itself tests as the actual point of failure.

On an all-gas range like the ZGP304LRSS, both the cooktop and the oven rely on gas ignition, so a technician confirms the gas supply and checks both ignition systems as part of a single visit rather than treating them as unrelated complaints.

Dual-fuel ranges like the ZDP304NTSS pair a gas cooktop with an electric convection oven under one control system, so a no-heat complaint on the oven side is diagnosed separately from a burner-ignition complaint on the cooktop side, even though both live in the same unit.

A self-clean lockout on the electric oven side of the ZDP30L4DSS is resolved the same way as on any Monogram wall oven — letting the cavity fully cool before the lock disengages — while the gas cooktop side is unaffected by that cycle entirely.
