After using the self cleaning function of the range we heard 3 long beeps and got an F-1 error code, I pressed clear and about 20 min's, later 3 beeps and F-1, I looked-up code and was directed to unplug wait 10 mins' or so, power up and see if code re-occurs it did, went to the next step and disconnected blue ribbon cables, repowered waited over an hour and no F -1 code, reset all connectors and reassembled controller assembly and repowered and F-1 code came back. From the manual it seems to indicate a faulty key pad, but in reading your info you indicate a thermistor might be the culprit, one other thing that may help is that pushing on the oven door will sometimes clear the F-1 code. Hope this is enough information to diagnose this problem.

ANSWER Hello Mike, The F1 error code indicates that the oven sensor is open. The first thing that you want to do is check your oven sensor 6322B62214Aresistance. The resistance should be 1090 ohms plus or minus 5 percent. If this is not correct then replace the oven sensor. If the oven sensor checks ok then check your wiring for the sensor up to the PCB EBR74632601. If this checks ok then replace the main PCB.
