My Repair & Advice
Replaced the Thermistor ($9) and the Thermostat ($19). It was a 60 minute fix by the time you pull out the oven and put it back. The oven times out and errors with an F9 code when the temperature does not reach a minimum 150 degrees.
First, turn off the breaker and pull out the oven (I had 6 screws into the cabinet). Take off the back panel for the upper and/or lower oven, depending on the fix. Mark the screws before unscrewing the back panel. Otherwise, you will not remember the correct holes (more holes than screws in the back panel). Replace the thermistor (unscrew in oven first), and then replace the thermostat (a 5 minute step). Both have quick wire release attachments. Replace the back panel and re-install oven. NOTE: It is easier if you can slide the oven completely out at the same height. The oven is very heavy and it may help you relocate the wires (in my case flex tube) so the oven fits snuggly back in its place without the wires getting caught. Test the oven before you re-attach to the cabinet. Don't EVER use the Clean Cycle AGAIN! NOTE: Re-attached all molding with double stick velcro in case I need to repair again. This way I won't worry about breaking he molding around the oven (when it happens again). FYI - saved about $400 in service.
