Whirlpool Range N N Oven is too hot

This mechanical oven thermostat controls cavity temperature. It senses heat with an attached capillary bulb and cycles the heating source to reach and maintain the set temperature for consistent, reliable baking performance.

• Regulates oven temperature by opening/closing internal contacts based on sensor bulb feedback
• Helps restore accurate preheat and steady cooking temperatures
• Common failure symptoms: won't reach set temperature, runs too hot, wide temperature swings, or continuous heating
• Provides direct temperature control on knob-operated models

• Disconnect power at the breaker before servicing; allow the oven to cool completely
• Handle the capillary tube carefully—avoid kinks or sharp bends
• Route and clip the sensor bulb exactly as originally installed for proper sensing
• Restore power and verify operation with an oven thermometer
