Hello Gene,
I was rudely awakened last night by incessant “beeping” of my rangetop.
I showed the “Fault Code” F1-8. I would appreciate some assistance in diagnosing what the problem might be. Also a readable wiring diagram would be of assistance.
Appliance - Jennair Rangetop/Oven
Model # - JGS8850ADS
Serial # 16900361GC
Approx 5 years old
Thank you in advance for you help.
Paul

Your error indicates a stuck key.
Usually this is the key pad but can be the control board.
The only way to confirm it is to use a meter and test the keys on the keypad (see the tech sheet).
Sometimes disconnecting/reconnecting and cleaning the ribbon cable (see below) will solve this but it usually it only works for open keys not shorted keys, so is a long shot
Unplug the unit
Open it up
Remove the ribbon cable from the keypad to the control board at the control board.
Clean the edge connector.
If it is the type where there is not a connector just the insulation is removed, it can be cleaned with a pencil eraser. Do not use an ink eraser as it is too abrasive.
Check the tracks in the ribbon cable for hairline cracks. A magnifying glass helps here.
Would not hurt to clean the connector on the board. Use electronics contact cleaner or isopropyl alcohol and a tooth brush. Be gentle and do not reconnect till all the solvent evaporates.
Reconnect everything and give it a try.
