Before you order, use Confirmed Fit
For advice and repair topics like this one, the biggest buying mistake is ordering on appearance alone. Search by the exact model number wherever possible, because small appliance revisions can use different seals, filters, motors, pumps, lamps, shelves, or trims.

Safety First
Disconnect the oven from the mains before starting. The thermostat capillary tube is delicate, so remove it carefully and route the replacement in the same position as the original.
Typical Replacement Steps
- Remove the control knob and access the rear of the thermostat assembly.
- Note the wire positions and mounting screws.
- Release the thermostat sensor or capillary from inside the cavity.
- Withdraw the old thermostat and route the new capillary in the same path.
- Reconnect wires, refit panels, and test operation.
When the Thermostat Is Suspect
- The oven overheats and burns food.
- The temperature swings are extreme or inconsistent.
- The oven never seems to reach or hold the selected heat correctly.

Do I need the full model number before ordering the replacement part?
Use the full model number exactly as shown on the rating plate. When Spares2Repair matches that model to a compatible part we call it Confirmed Fit. Similar-looking parts can differ across revisions, production runs, and variants, so model matching is the safest route before ordering.
What should I check before stripping the appliance down?
Confirm the fault symptoms first, isolate the appliance safely, and make sure the replacement part is model-matched before taking the appliance apart any further.
