MODEL OVERVIEW
About this model: GE PEB7226DFWW
PEB7226DFWW is GE's white 2.2 cu ft countertop microwave with 1,100 W output, a 16-inch turntable and optional built-in trim kits. Its exact-model listing confirms Popcorn and Reheat sensor controls. The linked manual prints this full SKU in its accessory table and explains SENSOR ERROR when steam is not detected as expected during sensor cooking.
Size, finish and installation choices
GE's exact product page describes PEB7226DFWW as a white microwave with 2.20 cubic feet of capacity and 1,100 watts of IEC-705 output. Its overall width is 24 1/8 inches, and GE lists a 16-inch turntable. Those are different measurements: the outside width matters for a counter location or opening, while the turntable diameter describes the rotating support for a dish. A large cavity figure does not by itself guarantee that every oversized container can turn freely. Read the complete model number, including DFWW, before selecting an accessory or replacement.
The GE listing permits countertop use and also describes the model as built-in capable. The linked manual gives unusually direct variant evidence: its optional-accessory table prints PEB7226DFWW beside JX7227DFWW for a 27-inch installation and JX7230DFWW for a 30-inch installation. Those kits are not interchangeable merely because the microwave body is the same. Compare the actual cabinet opening and the intended trim width with the relevant installation instructions. The manual names other PEB7226 finishes on that page, so the white suffix matters when matching visible trim rather than relying only on the family designation.
Why SENSOR ERROR appears
GE's page for this exact SKU lists Popcorn and Reheat among its sensor cooking controls. The linked manual explains that sensor cooking follows rising humidity from the food and adjusts time accordingly. On its Popcorn instructions, opening the door while POPCORN is still displayed produces SENSOR ERROR; the Reheat instructions give the same warning while REHEAT remains on the display. Reheat's remaining-time countdown begins only after steam is sensed. The display message therefore describes a sensor-cycle interruption or lack of expected steam, not proof that the humidity detector itself needs replacement.
The troubleshooting table separates two routes to SENSOR ERROR: the door was opened before steam could be detected, or steam was not detected within the maximum time. For the first, keep the door closed during an appropriate sensor program until the phase described by the manual completes. For the second, GE directs users to Cook Time for additional heating. The sensor section also warns against running sensor cooking twice in quick succession on the same portion and calls for microwave-safe containers with vented coverings. The condition of the food and the way steam escapes can matter to the reading.
Manual controls after an interrupted cycle
PEB7226DFWW has electronic touch controls on its product listing, while the linked manual gives two direct alternatives to a sensor program. Express Cook starts a one- to six-minute interval from the matching number pad, and Add 30 Sec extends a running interval by thirty seconds for each press. Those controls change time without asking the oven to interpret a new steam signal. After a SENSOR ERROR caused by missing steam, the troubleshooting chart specifically says to use Cook Time for more heating. Choose the prescribed manual-time setting rather than treating every unfinished portion as a reason to repeat Popcorn or Reheat immediately.
The same manual distinguishes SENSOR ERROR from a locked panel. If LOCKED appears, the chart says to hold Cancel/Off for about three seconds to unlock; that is a separate display state, not an explanation for steam sensing. The SENSOR ERROR row also says the message scrolls until Cancel/Off is pressed after an early door opening. Note the exact words shown, whether the door was opened, and whether a countdown had started before cancelling. Those observations help select the correct manual row without inferring a component failure from one message.
Care and a useful source check
The owner's manual says the glass turntable and its support must be seated when the oven operates; GE's exact-model page identifies the turntable as 16 inches. Remove it only according to the care instructions, and avoid putting the hot glass immediately into water. The manual calls for mild, nonabrasive detergent on the surfaces where the door seals against the oven. That cleaning point is distinct from the sensor's need for suitable, vented cookware. Keeping the contact area clean is routine care, not a substitute for following the manual's SENSOR ERROR branch.
This PDF is tied to PEB7226DFWW in two ways: GE links it from the exact product page, and page eleven prints the full SKU beside its white trim-kit numbers. Its cover uses the broader PEB7226 family name, so equipment that differs between finishes should still be checked against the exact product listing. The model page independently confirms the Popcorn and Reheat sensor controls involved in the manual's error explanation. For this variant, the actionable distinction is whether the door interrupted steam detection or no steam appeared in time; the manual gives Cook Time for the latter case.
