• Closes and opens the control circuit to maintain the oven at the selected temperature
• Can correct symptoms such as oven not reaching set temperature, overheating, or excessive cycling
• Works with the oven's control system and heating elements to stabilize bake and broil operations
• Mechanical design — avoid bending or damaging the sensing element/capillary

• One oven thermostat

• Disconnect power to the appliance before starting any service
• Handle the thermostat and sensing element carefully; do not kink or sharply bend the capillary
• Verify proper thermostat mounting and oven cavity seals for accurate temperature control
