This is what the f1 is telling you.You either have a bad touch pad or the computer board is bad.
* Here is a simple test that you can do to determine whether the clock or the touchpad are defective when the display reads F1: - Disconnect power to the range.- Gain access to the back of the ERC (electronic range control, or "clock"). - Unplug the touch pad ribbon connector from the ERC. This will be a flat wire about 1 ½" to 2" wide.- Make sure everything is clear and will not short out when power is turned back on. Replace any covers removed to gain access to the ERC.- Turn the power back on to the range. - Watch for the F-1 and listen for the beep. - If you get the F-1 and beep, replace the ERC. - If after approximately 60 Minutes you do not get the F-1 fault, replace the touch pad. NOTE: Some models incorporate the touch pad and the clock control as one part so F1 = bad clock control. Warning: If you do not feel comfortable doing this test or making this repair please contact a qualified appliance repair technician.
