Heating elements stay on continuously and oven temperature far exceeds the dial setting — thermostat has lost the ability to cycle the circuit off.
Oven bake element fails to reach set temperature or barely heats; thermostat is not closing the circuit to energise the element.
Oven temperature is consistently 50°F or more above or below dial setting, causing undercooked or burnt food despite correct time and temperature selection.
Oven swings between very hot and very cool during a single bake cycle; faulty thermostat cycling causes wildly inconsistent heat delivery.





💡 Pro Tip: How to Know Your Oven Thermostat Has Failed
Your part is likely the culprit if you notice any of the following:
⚠️ Oven runs noticeably hotter or cooler than the dial setting (more than 25°F off)
⚠️ Heating elements never cycle off — oven overheats to full power at any temperature setting
⚠️ Oven produces little or no heat even when elements are confirmed good
⚠️ Temperature fluctuates wildly during a bake cycle — food burns on outside while raw inside
🔍 Technician tip: Before replacing, test the oven temperature sensor (probe) for resistance — it should read approximately 1,080 Ω at room temperature. If sensor checks out and the oven still overheats or underheats, the thermostat body itself is the fault. Transfer wires one terminal at a time to avoid miswiring.
