Unplug the Whirlpool oven from the electrical wall outlet. Many homes today use anti-tip brackets that are installed in the floor and attached to the rear legs of the oven. Push the oven toward the wall slightly, and tip the rear of the oven up to clear the rear legs from the anti-tip brackets. Pull the oven forward so that you can access the rear of the oven.
Remove the screws that secure the back panel to the oven using a Phillips head screwdriver. Pull the back panel off the oven, and set it out of the way. Pull the knob off the thermostat on the face of the control panel.
Use the screwdriver to remove the two screws that secure the thermostat to the control console. The screws are on the face of the control console. Pull the thermostat off the inside of the control console. Use needle nose pliers to disconnect the wires attached to the thermostat terminals.
Go to the front of the oven, and open the oven door. Locate the thermal bulb that is mounted on the left wall of the oven. Unsnap the thermal bulb from the clips that secure the thermal bulb to the side wall, and push the thermal bulb through the hole in the back wall of the oven.
Go back to the rear of the oven, and finish pulling the thermal bulb out of the back wall of the oven. The thermal bulb connects to the thermostat using a capillary tube. The thermostat, thermal bulb and capillary tube are replaced as one unit. Take the thermostat and thermal bulb with you to an appliance repair shop to purchase a new set. Make sure that the new ones match the ones you pulled out of the oven.
Insert the thermal bulb through the back of the oven wall. Go around to the front of the oven, pull the thermal bulb through and snap the bulb into the retaining clips. Close the oven door, and go back to the rear of the oven.
Connect the wires to the oven thermostat by pushing the wire leads over the terminals. Place the thermostat into position on the inside of the control panel. Secure the thermostat to the control panel using the retaining screws. Reattach the control knob back onto the thermostat shaft from the control panel face.
Reattach the rear panel of the oven using the retaining screws. Go to the front of the oven, and slide the oven back against the wall and plug the oven power cord back into the wall outlet.
