MODEL OVERVIEW
About this model: GE JB655SKSS
JB655SKSS is GE's stainless-and-gray 30-inch convection range with a 5.3-cu-ft oven, radiant glass top and No Preheat Air Fry. Its JB655 guide documents F-plus-character errors.
Map the stainless and gray cooking surface
GE specifies JB655SKSS as a thirty-inch freestanding electric convection range with a 5.30-cubic-foot oven and stainless-steel/gray appearance. Its cooktop is gray patterned ceramic glass over radiant elements. The left front has a 9/6-inch 3100-W Power Boil element, while the right front has a 12/9-inch 3000-W dual element. Match each ring to a pan's flat base rather than choosing only by the name Power Boil. A six-inch 80-W center-rear zone is for holding already hot food, not bringing a cold dish to cooking temperature. The JB655 owner PDF is shared by finishes, so those precise colors and element positions come from this exact GE page. A HOT COOKTOP lamp can remain after switches are off until glass drops near 150°F. Cycling of an element can also reflect its protective temperature limiter, particularly with an empty, warped or badly positioned pan.
Choose Convection Bake or No Preheat Air Fry
The exact SKSS listing confirms both Convection Bake and No Preheat Air Fry in this 5.3-cu-ft cavity. They need different setup. Convection Bake moves heated air around multiple racks and the guide calls for preheating; cakes and cookies may benefit from a temperature set about 25°F lower when multiple racks are used. Leave space between pans instead of blocking airflow. Air Fry instead uses one rack without preheat, with a stated 300–500°F setting range. The guide favors position three and a single layer of food; crowded pieces trap moisture and brown unevenly. GE lists an Air Fry basket, JXAFTRAY1VSS, as optional. Its absence does not mean the oven lacks the mode, and a dark sheet pan can be used according to the cooking guide. Check the actual food temperature before serving.
Interpret F and door messages at the oven display
Electronic touchpads and a digital temperature display are confirmed on JB655SKSS, making the linked page-25 diagnostic relevant. A flashing F followed by a number or letter is called a function error, but the guide does not translate a particular suffix into a failed part. Press Cancel/Off, allow one hour for cooling and try again. If it recurs, GE instructs a full power disconnect for at least thirty seconds, then service if the error repeats. Record the full characters and what mode was running. LOCK DOOR means Self Clean was chosen while the door was not properly closed or latched. That differs from an F pattern. An ordinary Timer only counts down, while Cook Time ends oven operation at the programmed interval; confusing those controls can look like a heat fault.
Care for the actual stainless and glass surfaces
This model lists Self Clean, a removable full-width storage drawer and a stainless overlay on its oven door. Before self-cleaning, the manual calls for wiping heavy grease, removing cookware and shiny racks, then waiting for the door to unlock after cooldown. Never force the latch. The stainless surface should be wiped with the grain and appropriate mild or stainless cleaner; GE's separate black-slate finish advice is not a substitute for checking the SKSS material. For the radiant glass, use a ceramic cooktop cleaner after cooling and a pad intended for that surface. Avoid sliding rough-bottomed pans, which can leave metal marks or scratches. The storage drawer is for storage; if it binds after service, the troubleshooting section also mentions an obstructing cord or mis-seated drawer rail.
