MODEL OVERVIEW
About this model: GE PVM1790DRWW
PVM1790DRWW is a white GE Profile 1.7-cu-ft convection microwave above a range, with 1000-watt microwave output, two racks and a three-speed exhaust. Its sensor alert has specific door and steam causes.
A white Profile unit that also bakes
PVM1790DRWW is the white-on-white member of GE Profile's PVM1790 convection family. Its exact product listing gives a 1.70-cubic-foot cavity, 1000 watts of microwave output, a stainless interior and a removable 13.6-inch glass turntable. It hangs above a cooking range and has an externally vented hood with three fan speeds; the halogen lamp below it illuminates the burners. The panel combines touchpads with a selector dial, while an automatic night light and scrolling clock serve ordinary kitchen use. These details distinguish this unit from a white basic microwave sharing the same installation position. The linked owner's booklet prints CVM1790 and PVM1790 on the cover, so the DRWW suffix is established by GE's exact product link. For food that does not fit a preset, Time Cook I sets a time; Time Cook II can change power partway through cooking. Fish is among the listed sensor choices.
Use racks according to the active heating mode
The two supplied wire racks make this microwave a small heated-air oven as well. Page six reserves them for Convection Bake, Convection Roast and combination Fast Bake, and explicitly excludes them from ordinary microwave cooking. Convection uses an element and moving hot air to develop browning; Auto Recipe Conversion can lower a conventional recipe's entered temperature for that mode. Fast Bake also applies microwave energy, so its cookware limits differ from a pure convection bake: metal trim can arc, and glass or glass-ceramic is the recommended choice. Arrange one rack low for routine baking and allow space around the dish for air movement; a second rack serves two-level heated-air cooking. The Warm control holds food already cooked and hot at serving temperature, rather than cooking a cold meal. Choosing the mode before selecting rack and dish prevents a common configuration error.
Why a recently baked oven refuses sensor cooking
Sensor microwave cooking works from humidity released by food, not from an exact cooking time entered in advance. Keep the dish exterior and cavity dry, use a vented cover and do not open before the countdown. The manual warns that running a sensor program twice on one serving can burn it; if the first pass leaves it underdone, finish with Time Cook. Convection adds an important restriction on this particular machine. When the cavity exceeds 200 degrees Fahrenheit after Bake, Roast or Fast Bake, the display can say OVEN TOO HOT FOR SENSOR COOKING and offer an alternate timed method. Cooling the cavity restores sensor availability. That message is a temperature interlock, not evidence that the sensor has broken. The oven's fan may start automatically to protect components from cooking heat, so a running hood is not by itself a failure sign.
Read each panel message on its own terms
The troubleshooting table uses SENSOR ERROR for two separate events: the door opened before steam was detected, or steam did not arrive within the maximum sensing time. Keep the door shut until a countdown appears; for an underheated dish, add measured time with Time Cook. Neither event identifies a failed electronic part on its own. CONTROL LOCKED is another distinct display state; holding Clear/Off for about three seconds releases it. A blank clock after roughly thirty idle seconds is also described as the designed standby-saving behavior, so check whether opening the door wakes the display before assuming lost power. If the oven will not start, confirm the door closes firmly, Start/Pause was pressed and a required time or food type was entered. When seeking service, report the precise message, preceding cooking mode and whether the cavity was still hot.
