Hi...I want to know if i can leave the 3 racks inside for cleaning at the same time as the oven is cleaning

Not usually recommended, although the owner's manual says they CAN be. The internal oven temperatures often exceed 700 degress F during the self clean cycle and lasts over 4 hours. Temperatures of this extreme will not only discolor the oven racks, but may also cause them to warp and bend, which makes them harder to slide in and out of the oven. If the model number is correct, this information can be found on page 25 of your owner's manual. If you no longer have an owner's manual, you can obtain a FREE copy at managemylife.com. Just type in your model number under their "Manuals" link. For your convenience, here is a direct link:

If you have any questions, please post back and let me know. I hope this helps you.

It depends on the rack type. Do not leave the metal racks inside the oven during a self-clean cycle. They can be warped at the temperature of the cleaning cycle. If your oven has the porcelain-coated shelves, they can stay in the oven.

Clean large spills by hand with a non-abrasive cleanser before starting the self-clean cycle.

The manual for the JGBP90MEHBC and the JGBP90MEBBC is available from GE: http://products.geappliances.com/MarketingObjectRetrieval/Dispatcher?RequestType=PDF&Name=49-85131.PDF .

The manual for the older JGBP90MEA is available here: http://genet.geappliances.com/DocSearch/Dispatcher?REQUEST=ShowPDF&FileName=49-80036.PDF .

I hope this helps.
