Microwave Door Won't Latch

Why a Microwave Door Won't Latch

A microwave door that won't latch keeps the unit from starting at all, since the control board requires a confirmed closed-and-locked door before it energizes the magnetron. A broken door latch hook, the small plastic or metal piece the door presses against to engage the lock, is the most common cause and typically breaks from repeated daily use or a door slammed shut. A misaligned door, often from a bent hinge or a frame that's shifted slightly, can prevent the latch from lining up with the hook even when both parts are intact. A failed door switch assembly can also report a false open reading to the control board even when the door is physically closed and latched correctly. These three causes require different repairs, so inspecting the latch, hinge alignment, and switch assembly together is the only way to isolate which one is actually failing.
