Hotpoint RVM5160DHWW 1.6 cu ft Over-the-Range Microwave with 1000 Watts and Sensor Cooking MECH-NOPOWER Error Fix: No Power — Display Completely Blank

The microwave has no power at all — the display is dark, no buttons respond, and the interior light does not work — check that the outlet has power (for OTR models, the outlet is usually inside the cabinet above the microwave); if power is confirmed at the outlet, the most likely cause is a blown internal line fuse (a ceramic fuse inside the microwave cabinet); the fuse can blow from a power surge, door interlock switch failure, or a shorted component; WARNING: the high-voltage capacitor inside a microwave can retain a LETHAL charge (approximately 4,000 volts DC) even when the unit is unplugged — do NOT open the microwave cabinet unless you are trained in microwave repair and know how to safely discharge the capacitor
