Einleitung

A faulty temperature sensor can leave your oven stone-cold or turn it into a cremator. Replacing the sensor restores accurate heat control so your food bakes as intended. Follow this procedure to swap the plug-type sensor found in many built-in ovens and the capillary-tube thermostat used in older freestanding stoves.

Was du brauchst

Schritt 1 Disconnect power and remove the built-in oven

Pull the power cord from the mains before working on the appliance.
Slide the built-in oven out of the cabinet to expose the back panel.

Schritt 2 Remove rear housing screws

Remove every black screw securing the rear housing panels.
Beware of sharp sheet-metal edges that can cut skin.

Schritt 3 Disconnect the temperature sensor plug

Unplug the temperature sensor connector located on the back wall.

Schritt 4 Release and extract the sensor

Remove one sensor retaining screw completely and loosen the other slightly.
Pull the sensor straight out of the oven cavity.

Schritt 5 Install the new sensor

Insert the new sensor through the opening until its eyelet seats flush.
Tighten both retaining screws to secure the sensor.
Reconnect the sensor plug to the wiring harness.

Schritt 6 Reassemble the built-in oven

Reinstall the rear panels with their screws.
Push the oven back into the cabinet in its original position.

Schritt 7 Remove knob and record thermostat orientation

Pull off the temperature control knob on the freestanding stove.
Take a photo of the shaft so the flat side faces the same way during reassembly.

Schritt 8 Detach the thermostat from the control panel

Unscrew and remove the thermostat from the control panel.

Schritt 9 Lift the cooktop for interior access

Undo the screws on both sides that hold the cooktop.
Lift the cooktop slightly and support it to gain access without disconnecting wiring.

Schritt 10 Remove the analog sensor and capillary tube

Inside the oven, loosen the screw securing the sensor bulb and withdraw it.
Carefully guide the capillary tube out along its original path.
Do not bend or kink the tube because it can crack.

Schritt 11 Disconnect the tube from the thermostat

Photograph the capillary connection at the thermostat.
Disconnect the tube and remove the old thermostat from the stove.

Schritt 12 Fit the new thermostat and sensor

Lightly attach the new thermostat to the control panel.
Route the capillary tube gently to the oven cavity following the original path.
Seat the sensor bulb and tighten its retaining screw.
Fully tighten the thermostat mounting screws when alignment is correct.

Schritt 13 Close the stove housing

Lower the cooktop and reinstall its side screws.
Push the control knob back onto the thermostat shaft in the recorded orientation.

Schritt 14 Restore power and test operation

Plug the stove back in and test that the oven heats and regulates properly.
If temperature control is still incorrect, recheck all connections and routing.

Abschluss

With a new temperature sensor fitted, your oven should now reach and hold the set temperature, ending under- or over-baked meals. Always unplug the appliance before future work, and treat sharp panels and fragile capillary tubes with care to keep both you and the stove in good shape.
