KitchenAid KMHS120ESS

Model # KMHS120ESS · current generation

The KMHS120ESS is KitchenAid’s current over-the-range microwave, doing double duty as both a microwave and the range hood ventilation for the cooktop below it. Because those two functions share the same housing, a ventilation complaint and a microwave-electronics complaint are diagnosed as separate systems even though they’re both reported as “the microwave.”

FAQ

KitchenAid KMHS120ESS FAQ

Not necessarily — the ventilation fan motor and the microwave's cooking electronics are separate systems, so a weak or noisy fan doesn't indicate a cooking-power fault.

Gentle, consistent door handling and keeping the latch area free of grease buildup meaningfully reduces wear over time.
