Countertop microwaves are simpler to service than an over-the-range model since there’s no shared ventilation system to work around — most faults isolate cleanly to either the magnetron/high-voltage circuit or the door-latch safety switch, with nothing else built into the same housing to complicate diagnosis.

Visible sparking or arcing inside a Kenmore microwave is never something to keep running through — here’s what causes it and why it needs to stop immediately.

The metal grease filter on a Kenmore over-the-range microwave is one of the most neglected maintenance items in the kitchen — and ignoring it causes real problems.

Over-the-range Kenmore microwaves were an extremely common Sears-era product for decades, typically built by Whirlpool or LG depending on model year, and doubling as the range hood’s ventilation. Because cooking and ventilation functions share the same housing, both are checked together during a service visit.
