Why does my range hood turn on by itself?

Some models of range hoods have a sentry feature that monitors the air temperature above the cooktop. If the temperature gets hot enough to trip the sentry system, the exhaust fan turns on to cool the cooktop area.

When does a sentry fan turn on and off?

The sentry system uses a temperature sensor to monitor air temperature. If the fan turns on when the area above the cooktop is at room temperature, test the temperature sensor by using a multimeter to check its resistance.

The cooling fan relay is an electromagnetic switch that controls the power supply to the engine’s cooling fans. It ensures that the energy-intensive devices only run when needed, usually when the vehicle is immobile. When the engine temperature approaches unsafe levels, the vehicle’s computer or temperature switch turns on the cooling fan relay.

When do you turn on the cooling fan on a Mini Cooper?

When the engine coolant temperature reaches 108 degrees Celsius (due to heat soak), the cooling fan will activate until the coolant temperature drops below 105 degrees Celsius. During this period, the fan has a maximum run time of 900 seconds (15 minutes) due to power management. Ambient or oil temperature has no effect on this run time. 2.
