Oven Thermostats.
An oven or cooker thermostat controls the temperature inside the oven cavity by switching power to the element within a +/-10-15% tolerance.
Fault Diagnosis
When a thermostat is faulty, symptoms are typically binary: the oven won’t heat at all, or it constantly heats and fails to cut out, resulting in burnt food. Safety thermostats operate similarly but are preset to a single cut-off temperature to prevent overheating.
Technical Testing
Almost all thermostats “break” the live supply once set temperature is reached. If the oven is overheating, the circuit remains closed regardless of setting. If it won’t heat, the thermostat fails to “make” the circuit to power the element.
Electrical Safety Warning
Oven thermostats carry live mains power. They must never be worked on while power is applied to the oven or cooker. Always isolate the appliance from the mains before inspection or replacement.
Sourcing Requirements
When buying a thermostat, precision is crucial. While they often appear identical, they vary significantly in temperature ranges, fitments, and knob offsets.
Can't Find The Thermostat You Need?
We strive to simplify the process. If you encounter difficulties, our team is here to assist. Use our contact page or email as a first resort; we can lookup the exact part and identify cost-effective compatible options for you.
IMAGES AND SIZES ARE FOR ILLUSTRATION ONLY
Parts may vary in shape and size to the images shown as parts are model-specific and subject to change or alteration at any time without notice. This spare part will only fit the models as described in the listing unless specifically advised otherwise by us.
NOTE: Many oven thermostats can be used in different positions and are very specific to the make and model fitting. Please take care when ordering and don't rely solely on images as they largely all look the same!

Experts In
Smeg Spare Parts.
Smeg appliances are design icons, but their internal components are often shared with other brands. We use this overlap to save you money.
The Alternative Part Advantage
Smeg parts are frequently used across multiple brands. We identify when an "alternative" part is actually the exact same component from the same factory, just without the Smeg-branded packaging. This allows us to offer some of the lowest prices in the UK.
Fast Dispatch
Most common Smeg spares are stocked in the UK and ready for quick dispatch.
Specialist factory orders typically arrive within 7-10 working days, but some may take longer as advised.
Smeg Identification Requirements
Increasingly, Smeg requires the Service Index and Serial Number to determine the exact component revision. We cannot guarantee accuracy without these.
Understanding Smeg "Compatible" Spares
While some "pattern" parts are sometimes low-cost knock-offs, many of our compatible Smeg spares are Equivalent Replacements. That is to say, the same part only in different packaging.
Often, these are the original parts sourced directly from the component manufacturer (like Plaset, Askoll, or EGO) without the Smeg branding on the box.
Let Us Guide You
Trying to fathom which alternative is safe can be a challenge. We will always be honest with you: if a compatible part is high quality, we'll offer you both the original and the saving. If it's junk, we won't sell it.

Contact us with your model details. We can usually supply Smeg parts cheaper than most UK suppliers by leveraging our cross-brand technical knowledge.
