Jon for Model Number JGS8850ADS Have whirlpool JGS8850ADS range. Started beeping and malfunctioning showing error code F1-8. Repair man tested separating touch control from clock then a F1-7 showed up. He replaced clock assembly put together tested unit running a combination of different oven operations bake, broil, convection,dry etc... for an hour and 15-20 min. just fine. Unit went back into F1-8. He also noted the cooling fan (upper right corner rear) never came on to circulate air over electronics. Tested fan motor and associated wiring found it all good. Now unit shows F1-8 and F1-7 when touch pad ribbon is disconnected. He also cleaned contacts on touch pad ribbon. Should he try a touch pad now? Thanks Jon
Answer Jon, Yes, you will need to replace the WP74005739 control panel assembly (blk). The error codes: F1-8 Shorted key (pad) in membrane switch. F1-7 Membrane disconnected, indicates that the keypad is the problem area. The part is in stock and available at this time. Thanks, Read More...
