MODEL OVERVIEW
About this model: GE JVM3162RJSS
GE JVM3162RJSS is a 950-watt, 1.6-cubic-foot over-range microwave whose brief Loc display signals Control Lock-Out; the guide also covers its cooking and ventilation controls.
Match the 950-watt stainless/black configuration
The exact GE JVM3162RJSS is a stainless-and-black over-range microwave with a 1.6-cubic-foot cavity and a stated 950-watt output. GE also specifies a two-speed, 300-CFM vent fan, bright/night/off cooktop lighting and a 12.5-inch turntable. Those figures distinguish it from nearby GE models with different power or tray sizes; keep the complete RJSS suffix when ordering a part or looking up a manual. The PDF linked directly from this product page names JVM3162 on its cover alongside JNM3163. Its cooking-control drawing shows the relevant Cancel/Off key labeled Lock Controls, so the lock instructions belong to this control layout. The guide warns that some features vary across the two-model family, and its optional recirculating charcoal filter kit is not evidence that a particular JVM3162RJSS installation already has that kit.
Interpret the brief Loc message before testing power
A key clue on this panel is Loc, not a numbered fault code. The owner guide says that while Control Lock-Out is active, Loc appears briefly whenever a button is pressed. Hold Cancel/Off for about three seconds to unlock, then try a normal command. Another part of the same family guide calls this condition LOCKED in its troubleshooting table; that wording describes the locked state rather than a second simultaneous screen readout. The p20 table also distinguishes an entirely unpowered oven from a lit control panel that will not begin cooking. With a lit panel, check whether Start/Pause was actually pressed, whether the door is securely closed, and whether an earlier selection needs Cancel/Off. If the panel itself is dead, its fuse, breaker, plug and surge rows are a different branch. Replacing a board merely because a protected key produced Loc would misread the documented lock feature.
Use staged cooking and defrost deliberately
JVM3162RJSS combines ten power levels, Express Cook one through six minutes, Add 30 Sec and weight-or-time defrost. The manual says the Express number pads start immediately at level ten, while Add 30 Sec can extend a running countdown or start an immediate short cycle. Cook Time II can chain two timed stages with different power levels, which is more precise than repeatedly starting a high-power burst for a dish that needs gentler finishing. For defrosting, one press on Defrost selects weight and two select time; the guide calls for turning food and shielding already thawed parts where appropriate. Level two or three is given for delicate thawing, while full level ten is used for fast heating. The turntable may be turned off for a large dish, but this guide says it automatically returns to ON after Cook Time or Express Cook. A newly rotating plate after the next cycle is therefore expected behavior.
Separate fan, timer and display behavior
The display can show either a separate minute-timer countdown or the active cooking countdown; the guide identifies the keys that switch between them. That matters when someone thinks a number is a heating time but is actually watching the independent timer. Its sound control can mute ordinary beeps, yet the manual explicitly says fault beep signals cannot be disabled. The vent fan has manual high and low choices and may also start automatically as protection from excessive heat rising from the cooktop. It can stay on while the microwave cools even after cooking controls are off. A warm cavity floor caused by the cooktop light is separately called normal in the troubleshooting table. Note the exact displayed word, whether the fan is running, and whether a timer or Cook Time was selected before treating noise or a changing display as a fault; those observations distinguish several normal functions of this specific panel.
