MODEL OVERVIEW
About this model: GE JGB660SPSS
GE JGB660SPSS combines a 5.0-cu-ft self-clean gas oven, 18,000-BTU Power Boil burner and included nonstick griddle with separate F, LOC ON and LOCKED signals.
Verify the JGB660 equipment against the shared manual
JGB660SPSS is GE's stainless 30-inch gas range with one 5.0-cubic-foot oven, five sealed burners, a storage drawer and electronic touch controls with a digital temperature display. Its exact GE product page links a 70-page owner PDF whose cover names JGB660 and JGB670 self-cleaning ranges. That cover does not prove every pictured button belongs to this SKU. On page eleven the common panel marks Convection, Air Fry and WiFi as features of some models; GE's exact JGB660SPSS specification instead lists traditional cooking technology. The same exact record supports Self-Clean, an included nonstick griddle, control lock and an audible preheat signal. Read the product fields beside the common manual before choosing a program. The lower drawer here is for storage, not the separate broiler drawer found on other GE gas designs. Two oven racks come with the appliance; remove the appropriate items before a high-temperature clean rather than assuming that all racks may stay inside.
Tell three display conditions apart
The display can show three related-looking but different conditions. F followed by a number or letter is identified on page twenty-nine as a function error. Press Cancel/Off, allow the oven to cool for an hour and retry. If the code repeats, cut all power for at least thirty seconds before reconnecting; call service if it returns again, recording the full suffix. The manual gives no universal failed-part meaning for an unspecified F character. LOC ON means the touch controls have been deliberately locked. Holding Lock Controls for three seconds unlocks them, and Cancel/Off remains active during lockout. LOCKED is the separate door-status light associated with high-temperature self-clean: it can remain on while the cavity cools below the safe unlocking temperature. Do not force the door. LOCK DOOR is another prompt that can flash when a self-clean selection is made before the door is closed. Describing the exact displayed words is more useful than calling every locked state an error.
Prepare the actual self-clean cycle
This exact oven is specified as self-cleaning, so page twenty-two's high-temperature instructions apply. Start only from a room-temperature cavity and wipe away excessive grease and heavy spills beforehand. The guide recommends about three hours for moderate soil and five for heavy soil. Remove items other than any explicitly self-clean-rated black racks or compatible grates; ordinary silver nickel-plated racks should come out. Select Self Clean on the panel and press Start after closing the door. It remains locked throughout the cycle and during subsequent cooling, which is why an illuminated LOCKED light is often expected. Wait for the latch to release rather than pulling the handle; only after cooling wipe residual ash. Move pet birds to a separate well-ventilated room because the manual warns of sensitivity to self-clean fumes. The shared guide also describes Steam Clean as optional on some models, but this SKU's exact cleaning specification lists Self-Clean, not an assured steam setting.
Use Power Boil and the nonstick center griddle
The surface combines continuous cast-iron grates with a center oval burner and an included integrated nonstick griddle. GE rates the left-front Power Boil position at 18,000 BTU, the left-rear Precise Simmer unit at 5,000 and the center oval at 10,000; the right burners are 9,500 and 12,000 BTU. Match pan size to flame and use the small simmer position for delicate sauces. The griddle belongs above the center burner only. Page ten recommends preheating it for five minutes on High before food, then reducing to an appropriate cooking setting. The manual covers optional cast-iron accessories as well, but the exact product record names the included piece as nonstick. Do not overheat that plate empty or attack its coating with sharp metal tools. After it and surrounding grates cool, remove food residue and grease beneath it. A dirty burner port or displaced cap can cause ignition trouble without implying an oven F-code fault.
Set traditional oven functions and protect the control
For everyday oven cooking, use Bake or Broil from the traditional-mode section and wait for Start after entering the temperature. Keep the door shut while broiling and monitor fatty food closely. Cook Time can stop eligible heating at a programmed end, whereas the ordinary timer only signals and leaves the oven running. Delay Bake is present on the exact specification, but foods that spoil should not wait in a warm kitchen for an extended period before heating. The control lock can protect touch keys while wiping the panel; switch it off before attempting to cook. Exterior cleaning uses a soft cloth and mild soap or vinegar solution rather than abrasive powder. If a burner fails to light, inspect household power, gas availability and correctly seated cooled burner parts before calling service. Those ordinary checks are separate from the prescribed F-code reset. The JGB660SPSS should be described by its own self-clean, nonstick-griddle equipment, without borrowing optional convection or Air Fry instructions from the JGB670 pages.
