MODEL OVERVIEW
About this model: GE PVM1870DMWW
GE Profile PVM1870DMWW is a white 1.8-cu-ft, 1,100-W over-the-range microwave with sensor programs, a 14.25-inch turntable and external venting. Its linked guide defines SENSOR ERROR as a cooking-cycle issue.
Identify this white Profile microwave
PVM1870DMWW is the white GE Profile Spacemaker XL1800 microwave, with 1.80 cubic feet of cavity capacity and 1,100 watts of rated microwave output. The exact product page lists a 14.25-inch recessed glass turntable that can be turned on or off, ten power levels and electronic touch controls. Its sensor menu includes beverage, popcorn, reheat, vegetables, chicken and fish; the family manual also describes time cooking and auto defrost. This is an over-the-range model with an exhaust feature, and GE specifies external venting for the exact SKU. The shared PDF cover says Microwave Oven rather than printing the full sales suffix, so the model-specific product listing is essential for confirming the white finish, power, programs and ventilation arrangement.
Understand what the sensor actually reads
A sensor program does not use a fixed time in the same way as Time Cook. The manual explains that it watches humidity rising from food and then determines the remaining cooking interval. That is why it tells you to use a microwave-safe container with a lid or vented wrap, keep the outside of the dish and oven interior dry, and avoid tightly sealed plastic. Droplets already on the container can confuse steam detection. Opening the door before the display starts counting down interrupts the information the program needs. The guide also warns against repeating a sensor cycle immediately on the same portion because it may overcook or burn food. This matters on PVM1870DMWW because the exact SKU really does have the listed sensor controls.
Handle SENSOR ERROR without guessing a part
On physical PDF page 39, the troubleshooting chart prints SENSOR ERROR and lists two relevant conditions: the door was opened before steam could be detected, or steam did not appear within the program's maximum allowed time. The prescribed response is to keep the door closed until steam is sensed and a countdown appears, then use Time Cook for additional heating if needed. The message does not say that a humidity sensor has failed. Note which sensor pad was used, what food and cover were present, and whether the door opened during sensing. CONTROL LOCKED or LOCKED on that same page has a different cause: the control panel was deliberately locked. A warm oven floor caused by the cooktop light is likewise treated as normal rather than a sensor fault.
Choose time and defrost controls deliberately
If sensor conditions are unsuitable, the ten manual power levels give a separate way to control cooking. The guide explains that level 10 supplies full power, while lower levels cycle microwave energy and give heat time to spread inward; use Time Cook to select a duration instead of rerunning a failed sensor program. Auto Defrost uses the entered food weight and can signal Turn Food Over twice, which is a normal instruction rather than an error. The product's Quick Defrost and Time Defrost are other choices with different inputs. The minute timer can count while the oven operates but does not start heating by itself. A FOOD IS READY reminder after a completed cycle is also a status message. Distinguishing these texts prevents a normal prompt from being mislabeled as a fault.
Care for the vent and distinguish display states
For the hood function, the exact listing says externally vented; GE offers JX81B as an optional charcoal kit for recirculation setups, so do not assume a charcoal cartridge is already installed. The linked manual says the reusable metal grease filter must remain in place when the hood runs and should be washed about monthly or when dirty. Keep the recessed turntable and support installed for cooking, and let the glass cool before washing. The control panel should be wiped with a damp cloth rather than sprayed directly. If SENSOR ERROR recurs despite an appropriate covered dish and a closed door, record the program and circumstances for service instead of inferring a replacement part from the display alone.
