JMW9530AAB ERROR CODE F1

SOURCE: F1-1 error on Jenn-Air Range

if it is the stove that is in the picture the fault codes are in the door under the oven door.

Slone, F4 is the code for a shorted temperature sensor. This is the temp probe in the oven. There are 2-quarter inch screws holding it on. It should pull out through the insulation until the quick connect comes through. If you want to make sure, the sensor should ohm out at 1143 ohms at 100 degrees. I think you can be pretty sure that this is the problem. The part number I have is 704657. Catriver.

As indicated by others, the best solution for most people is to replace the touch pad assembly.
I went the cheap - time consuming route.

Using the information from this forum and others I decided that the F1-7 error message was due to the touch pad. When I saw the price of the assembly which includes the touch pad I decided to take a look inside. With the power off :-) I disconnected the touch pad ribbon connector from the socket. Using a tool fabricated from a broken hacksaw blade hot bent 90 degrees about 4mm from the end, re-hardened and sharpened to form a knive edge, I carefully loosened the touch pad around the perimeter. The touch pad is applied to the frame with a flexible adhesive, so I was able to pull it off slowly without permanent deformation.
I softened the adhesive with odorless mineral spirits and was able to remove the adhesive from the touch pad with paper towels. upon examination of the touch pad I noticed several breaks in the the printed traces. I carefully pulled away the laminate near the breaks, which were near the flexible ribbon connector from the touch pad. I used a the copper powder paint from a Permatex rear window defogger repair kit to (tediously) paint traces to complete the gaps in the printed traces. The outer trace, which runs around the periphery of the pad kept showing a very high resistance (> 5 megohms) until I scraped away a short light colored section of the printed trace and replaced that with the repair paint. The trace then showed a resistance of just under 1meg. I temporarily re-attached the touch pad with tape and the error code did not reappear. I set the clock and successfully tested several buttons.
Next step - seal the area around the trace repairs so I can get some more years out of the stove, until the next repair.
The cause of this is an obvious design flaw. The printed traces were all compromised in the area where there is no discernable protection over the traces, allowing moisture (I assume) to react with the conductive material in the traces.
