Microwave drawer will not open, close or stay closed

Rule out an obstruction, an overloaded drawer, the control lock and a power interruption, then reset at the breaker. Persistent faults point to the position/sensing switch, drawer motor, slides or the control; check for oversized mounting screws on new installs.

Microwave starts by itself or will not stop

A microwave that heats on its own is a fire hazard: unplug it and do not use it. The usual cause is a stuck relay or shorted triac on the control. On OTR units, a fan that starts by itself is often normal heat protection, and a light that stays on can be moisture.

Microwave has display/clock but won't start

Rule out user settings first (control lock, demo mode, Start not pressed, shipping spacer). If those are fine, the control is not seeing a closed door or is not driving its relays: door switches, latch, or control board.
