Oven Thermostats

Oven thermostats play a critical role in temperature regulation and cooking performance. They control the heating element based on the temperature setting you select, ensuring your oven reaches and maintains the correct heat throughout the cooking cycle. When a thermostat fails, you might notice issues like the oven overheating, underheating, or not heating at all, even if the elements themselves are fine.

Common signs your oven thermostat might need replacing include:

• Inconsistent or inaccurate cooking temperatures
• Food burning or staying undercooked despite correct settings
• The oven staying cold or failing to cycle on and off properly
• Heat continuing even after the oven is switched off

We stock replacement thermostats for a wide range of electric oven brands, including Westinghouse, Simpson, Electrolux, Fisher & Paykel, Elba, DeLonghi, Bosch, Smeg, Robinhood, Ariston, Indesit, ILVE, Whirlpool, Samsung, and Parmco. Whether you’re replacing a simple control thermostat or a more complex multi-sensor unit, each part is selected for compatibility and reliability.

Most oven thermostats are accessed by removing the back panel or control section of the oven, and installation generally requires a basic understanding of wiring—though many home DIYers can handle the job with care and the power switched off at the wall.

If you’re unsure which thermostat your oven uses, just send us your model number (usually found on the oven frame) and we’ll help you identify the right part.
