Your associate gave me an alternate part AP2140257. I would appreciate verification of the part number and also how I can remove the capillary tube from the bottom inside of the oven.
Yes the correct thermostat for your unit is part number 5303212745. To install this part you will need to pull the unit out from the wall. Remove the thermostat knob, and unplug the unit. Remove the rear cover over the control panel and the back of the unit. Open the oven door and remove the thermostat from the clip. Remove the screws on the control panel for the thermostat and disconnect the wires one at a time and put on the new thermostat. Once this is done then you will screw the new thermostat to the control panel to hold in place. You will then pull the thermostat probe out from the back of the unit and install the new one and attach to the clip. Reassemble the unit.
