MODEL OVERVIEW
About this model: GE JNM6171DFWW
GE JNM6171DFWW is a white recirculating over-range microwave with a programmable night light and LOCKED display; this guide separates those behaviors from faults.
Identify the recirculating white model
JNM6171DFWW is GE's white 1.7-cubic-foot over-range microwave specifically sold with recirculating venting. The exact specification gives 1,000 watts of microwave output, a two-speed 300-CFM fan, two incandescent cooktop bulbs and a recessed 11.5-inch glass turntable. These details identify the appliance more reliably than a generic JVM-family picture: the linked owner PDF covers JVM6170, JNM6171 and JVM6172, while the JNM prefix on the exact product page identifies this recirculating variant. The family illustration shows a touch panel and the underside light, but also labels an oven shelf as applying to some models. No shelf is assumed here. When describing a symptom, distinguish the white microwave's cooking cavity, its underneath lamps and its fan; one unit houses all three, but their states do not necessarily diagnose one another.
Understand the scheduled light and independent fan
The Auto Night Light is a particularly useful JNM6171DFWW feature. GE lists it for the exact SKU, together with a programmable night lamp. The linked guide says to set the clock and calendar first, then enter separate lamp-on and lamp-off times with AM/PM. Its Night indicator stays lit to remind you the schedule is active. An underside lamp that switches on later in the evening may therefore be following your stored times rather than suffering a stuck relay. Review the programmed schedule before treating the lamp as a fault. The fan is another circuit: one Vent Fan press chooses high, a second low, and a third off. The guide also says the fan may turn on automatically at low speed when cooktop heat is excessive and remain on after the surface controls are turned off while internal parts cool. A running fan, a lit Night indicator and the microwave cooking program are distinct observations.
Read the scrolling display before diagnosing a fault
This model has a scrolling digital clock, Display On/Off and a control lock on its exact product listing. In the owner guide, holding AM/PM about three seconds opens scroll-speed choices from one through five. Holding the zero key for about three seconds instead hides or restores the clock display while idle. Holding Cancel/Off for about three seconds controls Child Lock-Out. Only the last of these produces LOCKED on the display and prevents accidental operation. A dark idle clock is therefore a different case from a visible LOCKED message. If someone reports that the oven ignores a button, note whether the clock was intentionally hidden or the lock deliberately engaged before calling it a power failure. The independent Timer On/Off can also count minutes without microwave energy, while Start/Pause stops cooking without erasing the displayed program.
Handle cooking and no-start observations carefully
For a cooking complaint, start with the documented control state rather than a code copied from another microwave. The exact product page lists Reheat, but its family PDF also carries a generic SENSOR ERROR row on the troubleshooting page; that row alone does not establish sensor cooking on JNM6171DFWW. This article therefore assigns the model its verified LOCKED indicator, not an unproven sensor fault. The guide recommends leaving the turntable moving for ordinary results and permits stopping it for a large dish. If the unit will not start after unlocking, its table separates a breaker or fuse, a power surge, a partly inserted plug and an incompletely closed door. A floor warmed by the cooktop lamp is listed as normal. Before cleaning, unplug as directed, and describe the exact displayed word, fan/light state and attempted program if qualified service is needed.
Verified model details
The programmed Night indication means the underside lighting schedule is set.
